#1 Agentic AI is available for Gemini in Android Studio

Gemini in Android Studio is the AI-powered coding companion that makes you more productive at every stage of the dev lifecycle. At Google I/O 2025 we previewed new agentic AI experiences: Journeys for Android Studio and Version Upgrade Agent. These innovations make it easier for you to build and test code. We also announced Agent Mode, which was designed to handle complex, multi-stage development tasks that go beyond typical AI assistant capabilities, invoking multiple tools to accomplish tasks on your behalf. We’re excited to see how you leverage these agentic AI experiences which are now available in the latest preview version of Android Studio on the canary release channel.

You can also use Gemini to automatically generate Jetpack Compose previews, as well as transform UI code using natural language, saving you time and effort. Give Gemini more context by attaching images and project files to your prompts, so you can get more relevant responses. And if you’re looking for enterprise-grade privacy and security features backed by Google Cloud, Gemini in Android Studio for businesses is now available. Developers and admins can unlock these features and benefits by subscribing to Gemini Code Assist Standard or Enterprise editions.

#2 Build better apps faster with the latest stable release of Jetpack Compose

Compose is our recommended UI toolkit for Android development, used by over 60% of the top 1K apps on Google Play. We released a new version of our Jetpack Navigation library: Navigation 3, which has been rebuilt from the ground up to give you more flexibility and control over your implementation. We unveiled the new Material 3 Expressive update which provides tools to enhance your product's appeal by harnessing emotional UX, making it more engaging, intuitive, and desirable for your users. The latest stable Bill of Materials (BOM) release for Compose adds new features such as autofill support, auto-sizing text, visibility tracking, animate bounds modifier, accessibility checks in tests, and more! This release also includes significant rewrites and improvements to multiple sub-systems including semantics, focus and text optimizations.

These optimizations are available to you with no code changes other than upgrading your Compose dependency. If you’re looking to try out new Compose functionality, the alpha BOM offers new features that we're working on including pausable composition, updates to LazyLayout prefetch, context menus, and others. Finally, we've added Compose support to CameraX and Media3, making it easier to integrate camera capture and video playback into your UI with Compose idiomatic components.

#3 The new Kotlin Multiplatform (KMP) shared module template helps you share business logic

KMP enables teams to deliver quality Android and iOS apps with less development time. The KMP ecosystem continues to grow: last year alone, over 900 new KMP libraries were published. At Google I/O we released a new Android Studio KMP shared module template to help you craft and manage business logic, updated Jetpack libraries and new codelabs (Getting started with Kotlin Multiplatform and Migrating your Room database to KMP) to help you get started with KMP. We also shared additional announcements at KotlinConf.

Learn more about what we announced at Google I/O 2025 to help you build better apps, faster.

Agentic AI takes Gemini in Android Studio to the next level

Android Developers — Mon, 23 Jun 2025 17:00:00 +0000

Posted by Sandhya Mohan – Product Manager, and Jose Alcérreca – Developer Relations Engineer

Software development is undergoing a significant evolution, moving beyond reactive assistants to intelligent agents. These agents don't just offer suggestions; they can create execution plans, utilize external tools, and make complex, multi-file changes. This results in a more capable AI that can iteratively solve challenging problems, fundamentally changing how developers work.

At Google I/O 2025, we offered a glimpse into our work on agentic AI in Android Studio, the integrated development environment (IDE) focused on Android development. We showcased that by combining agentic AI with the built-in portfolio of tools inside of Android Studio, the IDE is able to assist you in developing Android apps in ways that were never possible before. We are now incredibly excited to announce the next frontier in Android development with the availability of 'Agent Mode' for Gemini in Android Studio.

These features are available in the latest Android Studio Narwhal Feature Drop Canary release, and will be rolled out to business tier subscribers in the coming days. As with all new Android Studio features, we invite developers to provide feedback to direct our development efforts and ensure we are creating the tools you need to build better apps, faster.

Agent Mode

Gemini in Android Studio's Agent Mode is a new experimental capability designed to handle complex development tasks that go beyond what you can experience by just chatting with Gemini.

With Agent Mode, you can describe a complex goal in natural language — from generating unit tests to complex refactors — and the agent formulates an execution plan that can span multiple files in your project and executes under your direction. Agent Mode uses a range of IDE tools for reading and modifying code, building the project, searching the codebase and more to help Gemini complete complex tasks from start to finish with minimal oversight from you.

To use Agent Mode, click Gemini in the sidebar, then select the Agent tab, and describe a task you'd like the agent to perform. Some examples of tasks you can try in Agent Mode include:

Build my project and fix any errors
Extract any hardcoded strings used across my project and migrate to strings.xml
Add support for dark mode to my application
Given an attached screenshot, implement a new screen in my application using Material 3

The agent then suggests edits and iteratively fixes bugs to complete tasks. You can review, accept, or reject the proposed changes along the way, and ask the agent to iterate on your feedback.

Gemini breaks tasks down into a plan with simple steps. It also shows the list of IDE tools it needs to complete each step.

While powerful, you are firmly in control, with the ability to review, refine and guide the agent’s output at every step. When the agent proposes code changes, you can choose to accept or reject them.

The Agent waits for the developer to approve or reject a change.

Additionally, you can enable “Auto-approve” if you are feeling lucky

Top 3 things to know for AI on Android at Google I/O ‘25

Android Developers — Mon, 23 Jun 2025 16:59:48 +0000

Posted by Kateryna Semenova – Sr. Developer Relations Engineer

AI is reshaping how users interact with their favorite apps, opening new avenues for developers to create intelligent experiences. At Google I/O, we showcased how Android is making it easier than ever for you to build smart, personalized and creative apps. And we’re committed to providing you with the tools needed to innovate across the full development stack in this evolving landscape.

This year, we focused on making AI accessible across the spectrum, from on-device processing to cloud-powered capabilities. Here are the top 3 announcements you need to know for building with AI on Android from Google I/O ‘25:

#1 Leverage the efficiency of Gemini Nano for on-device AI experiences

For on-device AI, we announced a new set of ML Kit GenAI APIs powered by Gemini Nano, our most efficient and compact model designed and optimized for running directly on mobile devices. These APIs provide high-level, easy integration for common tasks including text summarization, proofreading, rewriting content in different styles, and generating image description. Building on-device offers significant benefits such as local data processing and offline availability at no additional cost for inference. To start integrating these solutions explore the ML Kit GenAI documentation, the sample on GitHub and watch the "Gemini Nano on Android: Building with on-device GenAI" talk.

#2 Seamlessly integrate on-device ML/AI with your own custom models

The Google AI Edge platform enables building and deploying a wide range of pretrained and custom models on edge devices and supports various frameworks like TensorFlow, PyTorch, Keras, and Jax, allowing for more customization in apps. The platform now also offers improved support of on-device hardware accelerators and a new AI Edge Portal service for broad coverage of on-device benchmarking and evals. If you are looking for GenAI language models on devices where Gemini Nano is not available, you can use other open models via the MediaPipe LLM Inference API.

Serving your own custom models on-device can pose challenges related to handling large model downloads and updates, impacting the user experience. To improve this, we’ve launched Play for On-Device AI in beta. This service is designed to help developers manage custom model downloads efficiently, ensuring the right model size and speed are delivered to each Android device precisely when needed.

For more information watch “Small language models with Google AI Edge” talk.

#3 Power your Android apps with Gemini Flash, Pro and Imagen using Firebase AI Logic

For more advanced generative AI use cases, such as complex reasoning tasks, analyzing large amounts of data, processing audio or video, or generating images, you can use larger models from the Gemini Flash and Gemini Pro families, and Imagen running in the cloud. These models are well suited for scenarios requiring advanced capabilities or multimodal inputs and outputs. And since the AI inference runs in the cloud any Android device with an internet connection is supported. They are easy to integrate into your Android app by using Firebase AI Logic, which provides a simplified, secure way to access these capabilities without managing your own backend. Its SDK also includes support for conversational AI experiences using the Gemini Live API or generating custom contextual visual assets with Imagen. To learn more, check out our sample on GitHub and watch "Enhance your Android app with Gemini Pro and Flash, and Imagen" session.

These powerful AI capabilities can also be brought to life in immersive Android XR experiences. You can find corresponding documentation, samples and the technical session: "The future is now, with Compose and AI on Android XR".

I/O 2025: What's new in Google Play

Android Developers — Thu, 22 May 2025 17:51:13 +0000

Posted by Paul Feng, VP of Product Management, Google Play

At Google Play, we're dedicated to helping people discover experiences they'll love, while empowering developers like you to bring your ideas to life and build successful businesses.

At this year’s Google I/O, we unveiled the latest ways we’re empowering your success with new tools that provide robust testing and actionable insights. We also showcased how we’re continuing to build a content-rich Play Store that fosters repeat engagement alongside new subscription capabilities that streamline checkout and reduce churn.

Check out all exciting developments from I/O that will help you grow your business on Google Play. Continue reading or watch the session to dive in.

Helping you succeed every step of the way

Last month, we introduced our latest Play Console updates focused on improving quality and performance. A redesigned app dashboard centered around four developer objectives (Test and release, Monitor and improve, Grow users, Monetize) and new Android vitals metrics offer quick insights and actionable suggestions to proactively improve the user experience.

Get more actionable insights with new Play Console overview pages

Building on these updates, we've launched dedicated overview pages for two developer objectives: Test and release and Monitor and improve. These new pages bring together more objective-related metrics, relevant features, and a "Take action" section with contextual, dynamic advice. Overview pages for Grow and Monetize will be coming soon.

Halt fully-rolled out releases when needed

Historically, a release at 100% live meant there was no turning back, leaving users stuck with a flawed version until a new update rolled out. Soon, you'll be able to halt fully-live releases, through Play Console and the Publishing API to stop the distribution of problematic versions to new users.

You'll soon be able to halt fully live releases directly from Play Console and the Publishing API, stopping the distribution of problematic versions to new users.

Optimize your store listings with better management tools and metrics

We launched two tools to enhance your store listings. The asset library makes it easy to upload, edit, and view your visual assets. Upload them from Google Drive, organize with tags, and crop for repurposing. And with new open metrics, you gain deeper insights into listing performance so you can better understand how they attract, engage, and re-engage users.

Stay ahead of threats with the Play Integrity API

We're committed to robust security and preventing abuse so you can thrive on Play’s trusted platform. The Play Integrity API continuously evolves to combat emerging threats, with these recent enhancements:

Stronger abuse detection for all developers that leverages the latest Android hardware-security with no developer effort required.
Device security update checks to safeguard your app’s sensitive actions like transfers or data access.
Public beta for device recall which enables you to detect if a device is being reused for abuse or repeated actions, even after a device reset. You can express interest in this beta.

Unlocking more discovery and engagement for your apps and its content

Last year, we shared our vision for a content-rich Google Play that has already delivered strong results. Year-over-year, Apps Home has seen over a 25% increase in average monthly visitors with apps seeing a 10% growth in acquisitions and double-digit growth in app spend for those monetizing on Google Play. Building on that vision, we're introducing even more updates to elevate your discovery and engagement, both on and off the store.

For example, curated spaces, launched last year, celebrate seasonal interests like football (soccer) in Brazil and cricket in India, and evergreen interests like comics in Japan. By adding daily content—match highlights, promotions, and editorial articles directly on the Apps Home—these spaces foster discovery and engagement. Curated spaces are a hit with over 920,000 highly engaged users in Japan returning to the comics space monthly. Building on this momentum, we are expanding to more locations and categories this year.

Our curated spaces add daily content to foster repeat discovery and engagement.

We're launching new topic browse pages that feature timely, relevant, and visually engaging content. Users can find them throughout the Store, including Apps Home, store listing pages, and search. These pages debut this month in the US with Media & Entertainment, showcasing over 100,000 shows, movies, and select sports. More localized topic pages will roll out globally later this year.

New topic browse pages for media and entertainment are rolling out this month in the US.

We’re expanding Where to Watch to more markets, including the UK, Korea, Indonesia, and Mexico, to help users find and deep-link directly into their subscribed apps for movies and TV. Since launching in the US in November 2024, we've seen promising results: People who view app content through Where to Watch return to Play more frequently and increase their content search activity by 30%.

We're also enhancing how your content is displayed on the Play Store. Starting this July, all app developers can add a hero content carousel and a YouTube playlist carousel to their store listings. These formats will help showcase your best content and drive greater user engagement and discovery.

For apps best experienced through sound, we're launching audio samples on the Apps Home. A simple tap offers users a brief escape into your audio content. In early testing, audio samples made users 3x more likely to install or open an app! This feature is now available for all Health & Wellness app developers with users in the US, with more categories and markets coming soon. You can express your interest in promoting audio content.

We're enhancing how your content is displayed on the Play Store, offering new ways to showcase your app and drive user engagement.

Helping you take advantage of deeper engagement on Play, on and off the Store

Last year, we introduced Engage SDK, a unified solution to deliver personalized content and guide users to relevant in-app experiences. Integrating it unlocks surfaces like Collections, our immersive full-screen experience bringing content directly to the user's home screen.

We're rolling out updates to expand your content’s reach even further:

Engage SDK content is coming to the Play Store this summer, in addition to existing spaces like Collections and Entertainment Space on select Android tablets.
New content categories are now supported, starting today with Travel.
Collections are rolling out globally to Google Play markets starting today, including Brazil, India, Indonesia, Japan, and Mexico.

Integrate with Engage SDK today to take advantage of this new expansion and boost re-engagement. Try our codelab to test the ease of publishing content with Engage SDK and express interest in the developer preview.

Engage SDK now supports Collections for Travel. Users can find timely itineraries and recent searches, all in one convenient place.

Maximizing your revenue with subscriptions enhancements

With over a quarter-billion subscriptions, Google Play is one of the world's largest subscriptions platforms. We're committed to helping you turn engaged users into revenue growth by continually enhancing our tools to meet evolving customer needs.

To streamline your purchase flow, we’re introducing multi-product checkout for subscriptions. This lets you sell subscription add-ons alongside base subscriptions, all under a single, aligned payment schedule. Users get a simplified experience with one price and one transaction, while you gain more control over how subscribers upgrade, downgrade, or manage their add-ons.

You can now sell base subscriptions and add-ons together in a single, streamlined transaction.

To help you retain more of your subscribers, we’re now showcasing subscription benefits in more places across Play – including the Subscriptions Center, in reminder emails, and during purchase and cancellation flows. This increased visibility has already reduced voluntary churn by 2%. Be sure to enter your subscription benefits in Play Console so you can leverage this powerful new capability.

To help reduce voluntary churn, we’re showcasing your subscriptions benefits across Play.

Reducing involuntary churn is a key factor in optimizing your revenue. When payment methods unexpectedly decline, users might unintentionally cancel. Now, instead of immediate cancellation, you can now choose a grace period (up to 30 days) or an account hold (up to 60 days). Developers who increased the decline recovery period – from 30 to 60 days – saw an average 10% reduction in involuntary churn for renewals.

On top of this, we're expanding our commitment to get more buyers ready for purchases throughout their entire journey. This includes prompting users to set up payment methods and verification right at device setup. After setup, we've integrated prompts into highly visible areas like the Play and Google account menus. And as always, we’re continuously enabling payments in more markets and expanding payment options. Plus, our AI models now help optimize in-app transactions by suggesting the right payment method at the right time, and we're bringing buyers back with effective cart abandonment reminders.

Grow your business on Google Play

Our latest updates reinforce our commitment to fostering a thriving Google Play ecosystem. From enhanced discovery and robust tools to new monetization avenues, we're empowering you to innovate and grow. We're excited for the future we're building together and encourage you to use these new capabilities to create even more impactful experiences. Thank you for being an essential part of the Google Play community.

Android Developers — Thu, 22 May 2025 17:15:07 +0000

Posted by Noam Gefen – Product Manager, Android for Cars, Sole Alborno – Product Manager, Gemini, and Ben Sagmoe – Developer Relations Engineer, Android for Cars

The in-car experience continues to evolve rapidly, and Google remains committed to pushing the boundaries of what's possible. At Google I/O 2025, we're excited to unveil the latest advancements for drivers, car manufacturers, and developers, furthering our goal of a safe, seamless, and helpful connected driving experience.

Today's car cabins are increasingly digital, offering developers exciting new opportunities with larger displays and more powerful computing. Android Auto is now supported in nearly all new cars sold, with almost 250 million compatible vehicles on the road.

We're also seeing significant growth in cars powered by Android Automotive OS with Google built-in. Over 50 models are currently available, with more launching this year. This growth is fueled by a thriving app ecosystem, including over 300 apps already available on the Play Store. These include apps optimized for a safe and seamless experience while driving as well as entertainment apps for while you're parked and waiting in your car—many of which are adaptive mobile apps that have been seamlessly brought to cars through the Car Ready Mobile Apps Program.

A vibrant developer community is essential to delivering these innovative in-car experiences utilizing the different screens within the car cabin. This past year, we've focused on key areas to help empower developers to build more differentiated experiences in cars across both platforms, as we embark on the Gemini era in cars.

Gemini for Cars

Exciting news for in-car experiences: Gemini, Google's advanced AI, is coming to vehicles! This unlocks a new era of safe and helpful interactions on the go.

Gemini enables natural voice conversations and seamless multitasking, empowering drivers to get more done simply by speaking naturally. Imagine effortlessly finding charging stations or navigating to a location pulled directly from an email, all with just your voice.

You can learn how to leverage Gemini's potential to create engaging in-car experiences in your app.

Gemini for cars will be rolling out in the coming months. Get ready to build the next generation of in-car AI experiences!

New developer programs and tools

Last year, we introduced car app quality tiers to inspire developers to create high quality in-car experiences. By developing your app in compliance with the Car ready tier, you can bring video, gaming, or browser apps to run while parked in cars with Google built-in with almost no additional effort. Learn more about Car Ready Mobile Apps.

Your app can further shine in cars within the Car optimized and Car differentiated tiers to unlock experiences while the car is in motion, and also when transitioning between parked and driving modes, while utilizing the different screens within the modern car cabin. Check the car app quality guidelines for details.

To start with, across both Android Auto and for cars with Google built-in, we've made some exciting improvements for Car App Library:

The Weather app category has graduated from beta: any developer can now publish weather apps to production tracks on both Android Auto and cars with Google Built-in. Before you publish your app, check that it meets the quality guidelines for weather apps.

Designing templated apps is easier than ever with the Car App Templates Design Kit we just published on Figma.

Two new templates, the SectionedItemTemplate and MediaPlaybackTemplate, are now available in the Car App Library 1.8 alpha release for use on Android Auto. These templates are a great fit for building templated media apps, allowing for increased customization in layout and browsing structure.

On Android Auto, many new app categories and capabilities are now in beta:

We are adding support for Building media apps with the Car App Library, enabling media app developers to build both richer and more complete experiences that users are used to on their phones. During beta, developers can build and publish media apps built using the Car App Library to internal testing and closed testing tracks. You can also express interest in being an early access partner to publish to production while the category is in beta. See Build a templated media app to learn more and get started.

The communications category is in beta. We've simplified calling integration for calling apps by utilizing the CallsManager Jetpack API. Together with the templates provided by the Car App Library, this enables communications apps to build features like full message history, upcoming meetings list, rich in-call views, and more. During beta, developers can build and publish communications apps to internal testing and closed testing tracks. You can also express interest in being an early access partner to publish to production while the category is in beta.

Games are now supported in Android Auto, while parked, on phones running Android 15 and above. You can already find some popular titles like Angry Birds 2, Farm Heroes Saga, Candy Crush Soda Saga and Beach Buggy Racing 2. To add support for Android Auto to your own app, see Build games for cars and Add support for Android Auto to your parked app. The Games category is in Beta and developers can publish games to internal testing and closed testing tracks. You can also express interest in being an early access partner to publish to production while the category is in beta.

Finally, we have further simplified building, testing and distribution experience for developers building apps for Android Automotive OS cars with Google built-in:

Announcing Jetpack Navigation 3

Android Developers — Wed, 21 May 2025 20:34:52 +0000

Posted by Don Turner - Developer Relations Engineer

Navigating between screens in your app should be simple, shouldn't it? However, building a robust, scalable, and delightful navigation experience can be a challenge. For years, the Jetpack Navigation library has been a key tool for developers, but as the Android UI landscape has evolved, particularly with the rise of Jetpack Compose, we recognized the need for a new approach.

Today, we're excited to introduce Jetpack Navigation 3, a new navigation library built from the ground up specifically for Compose. For brevity, we'll just call it Nav3 from now on. This library embraces the declarative programming model and Compose state as fundamental building blocks.

Why a new navigation library?

The original Jetpack Navigation library (sometimes referred to as Nav2 as it's on major version 2) was initially announced back in 2018, before AndroidX and before Compose. While it served its original goals well, we heard from you that it had several limitations when working with modern Compose patterns.

One key limitation was that the back stack state could only be observed indirectly. This meant there could be two sources of truth, potentially leading to an inconsistent application state. Also, Nav2's NavHost was designed to display only a single destination – the topmost one on the back stack – filling the available space. This made it difficult to implement adaptive layouts that display multiple panes of content simultaneously, such as a list-detail layout on large screens.

Figure 1. Changing from single pane to multi-pane layouts can create navigational challenges

Founding principles

Nav3 is built upon principles designed to provide greater flexibility and developer control:

You own the back stack: You, the developer, not the library, own and control the back stack. It's a simple list which is backed by Compose state. Specifically, Nav3 expects your back stack to be SnapshotStateList<T> where T can be any type you choose. You can navigate by adding or removing items (Ts), and state changes are observed and reflected by Nav3's UI.

Get out of your way: We heard that you don't like a navigation library to be a black box with inaccessible internal components and state. Nav3 is designed to be open and extensible, providing you with building blocks and helpful defaults. If you want custom navigation behavior you can drop down to lower layers and create your own components and customizations.

Pick your building blocks: Instead of embedding all behavior within the library, Nav3 offers smaller components that you can combine to create more complex functionality. We've also provided a "recipes book" that shows how to combine components to solve common navigation challenges.

Figure 2. The Nav3 display observes changes to the developer-owned back stack.

Key features

Animations: Built-in transition animations are provided for changes in destination, including for predictive back. It also has a flexible API for custom animation behavior, allowing animations to be overridden at both the app and the individual screen level.

Adaptive layouts: A flexible layout API (named Scenes) allows you to render multiple destinations in the same layout (for example, a list-detail layout on large screen devices). This makes it easy to switch between single and multi-pane layouts.

State scoping: Enables state to be scoped to destinations on the back stack, including optional ViewModel support via a dedicated Jetpack lifecycle library.

Modularity: The API design allows navigation code to be split across multiple modules. This improves build times and allows clear separation of responsibilities between feature modules.

Figure 3. Custom animations and predictive back are easy to implement, and easy to override for individual destinations.

Basic code example

To give you an idea of how Nav3 works, here's a short code sample.

// Define the routes in your app and any arguments.
data object Home
data class Product(val id: String)

// Create a back stack, specifying the route the app should start with.
val backStack = remember { mutableStateListOf<Any>(Home) }

// A NavDisplay displays your back stack. Whenever the back stack changes, the display updates.
NavDisplay(
    backStack = backStack,

    // Specify what should happen when the user goes back
    onBack = { backStack.removeLastOrNull() },

    // An entry provider converts a route into a NavEntry which contains the content for that route.
    entryProvider = { route ->
        when (route) {
            is Home -> NavEntry(route) {
                Column {
                    Text("Welcome to Nav3")
                    Button(onClick = {
                        // To navigate to a new route, just add that route to the back stack
                        backStack.add(Product("123"))
                    }) {
                        Text("Click to navigate")
                    }
                }
            }
            is Product -> NavEntry(route) {
                Text("Product ${route.id} ")
            }
            else -> NavEntry(Unit) { Text("Unknown route: $route") }
        }
    }
)

Get started and provide feedback

To get started, check out the developer documentation, plus the recipes repository which provides examples for:

common navigation UI, such as a navigation rail or bar
conditional navigation, such as a login flow
custom layouts using Scenes

We plan to provide code recipes, documentation and blogs for more complex use cases in future.

Nav3 is currently in alpha, which means that the API is liable to change based on feedback. If you have any issues, or would like to provide feedback, please file an issue.

Nav3 offers a flexible and powerful foundation for building modern navigation in your Compose applications. We're really excited to see what you build with it.

Google I/O 2025: What’s new in Android development tools

Android Developers — Tue, 20 May 2025 22:54:14 +0000

Posted by Mayank Jain – Product Manager, Android Studio

Android Studio continues to advance Android development by empowering developers to build better app experiences, faster. Our focus has been on improving AI-driven functionality with Gemini, streamlining UI creation and testing, and helping you future-proof apps for the evolving Android ecosystem. These innovations accelerate development cycles, improve app quality, and help you stay ahead in the fast-paced world of mobile development.

You can check out the What’s new in Android Developer Tools session at Google I/O 2025 to see some of the new features in action or better yet, try them out yourself by downloading Android Studio Narwhal Feature Drop (2025.2.1) in the preview release channel. Here’s a look at our latest developments:

Get the latest Gemini 2.5 Pro model in Android Studio

The power of artificial intelligence through Gemini is now deeply integrated into Android Studio, helping you at all stages of Android app development. Now with access to Gemini 2.5 Pro, we're continuing to look for new ways to use AI to supercharge Android development — and help you build better app experiences, faster.

Journeys for Android Studio

We’re also introducing agentic AI with Gemini in Android Studio.Testing your app is now much easier when you create journeys - just describe the actions and assertions in natural language for the user journeys you want to test, and Gemini performs the tests for you. Creating journeys lets you test your app’s critical user journeys across various devices without writing extensive code. You can then run these tests on local physical or virtual Android devices to validate that the test worked as intended by reviewing detailed results directly within the IDE. Although the feature is experimental, the goal is to increase the speed that you can ship high-quality code, while significantly reducing the amount of time you spend manually testing, validating, or reproducing issues.

Journeys for Android Studio uses Gemini to test your app.

Suggested fixes for crashes with Gemini

The App Quality Insights panel has a great new feature. The crash insights now analyzes your app's source code referenced from the crash, and not only offers a comprehensive analysis and explanation of the crash, in some cases it even offers a source fix! With just a few clicks, you are able to review the changes, accept the code suggestions, and push the changes to your source control. Now you can determine the root cause of a crash and fix it much faster!

Improved tools for future-proofing and testing your Android apps

We’ve enhanced some of your favorite features so that you can test more confidently, future-proof your apps, and ensure app compatibility across a wide range of devices and Android versions.

Streamlined testing with Backup and Restore support

Android Studio offers built-in Backup and Restore support by letting you trigger app backups on connected devices directly from the Running Devices window. You can also configure your Run/Debug settings to automatically restore from a previous backup when launching your app. This simplifies the process of validating your app's Backup and Restore implementation and speeds up development by reducing manual setup for testing.

Streamlined testing with Backup and Restore support

Android’s transition to 16 KB Page Size

The underlying architecture of Android is evolving, and a key step forward is the transition to 16 KB page sizes. This fundamental change requires all Android apps with native code or dependencies to be recompiled for compatibility. To help you navigate this transition smoothly, Android Studio now offers proactive warnings when building APKs or Android App Bundles that are incompatible with 16 KB devices. Using the APK Analyzer, you can also find out which libraries are incompatible with 16 KB devices. To test your apps in this new environment, a dedicated 16 KB emulator target is also available in Android Studio alongside existing 4 KB images.

Android’s transition to 16 KB page size

Backup and Sync your Studio settings

When you sign in with your Google account or a JetBrains account in Android Studio, you can now sync your customizations and preferences across all installs and restore preferences automatically on remote Android Studio instances. Simply select “Enable Backup and Sync” while you’re logging in to Android Studio, or from the Settings > Backup and Sync page, and follow the prompts.

Increasing developer productivity with Android’s Kotlin Multiplatform improvements

Kotlin Multiplatform (KMP) enables teams to reach new audiences across Android and iOS with less development time. Usage has been growing in the developer community, with apps such as Google Docs now using it in production. We’ve released new Android Studio KMP project templates, updated Jetpack libraries and new codelabs (Get Started with KMP and Migrate Existing Apps to Room KMP) to help developers who are looking to get started with KMP.

Posted by Ben Trengrove - Developer Relations Engineer, Matt Dyor - Product Manager
To empower Android developers, we’re excited to announce Android Studio’s new Kotlin Multiplatform (KMP) Shared Module Template. This template was specifically designed to allow developers to use a single codebase and apply business logic across platforms. More specifically, developers will be able to add shared modules to existing Android apps and share the business logic across their Android and iOS applications.

This makes it easier for Android developers to craft, maintain, and most importantly, own the business logic. The KMP Shared Module Template is available within Android Studio when you create a new module within a project.

Shared Module Templates are found under the New Module tab

A single code base for business logic

Most developers have grown accustomed to maintaining different code bases, platform to platform. In the past, whenever there’s an update to the business logic, it must be carefully updated in each codebase. But with the KMP Shared Module Template:

Developers can write once and publish the business logic to wherever they need it.

Engineering teams can do more faster.

User experiences are more consistent across the entire audience, regardless of platform or form factor.

Releases are better coordinated and launched with fewer errors.

Customers and developer teams who adopt KMP Shared Module Templates should expect to achieve greater ROI from mobile teams who can turn their attention towards delighting their users more and worrying about inconsistent code less.

KMP enthusiasm

The Android developer community remains very excited about KMP, especially after Google I/O 2024 where Google announced official support for shared logic across Android and iOS. We have seen continued momentum and enthusiasm from the community. For example, there are now over 1,500 KMP libraries listed on JetBrains' klibs.io.

Our customers are excited because KMP has made Android developers more productive. Consistently, Android developers have said that they want solutions that allow them to share code more easily and they want tools which boost productivity. This is why we recommend KMP; KMP simultaneously delivers a great experience for Android users while boosting ROI for the app makers. The KMP Shared Module Template is the latest step towards a developer ecosystem where user experience is consistent and applications are updated seamlessly.

Large scale KMP adoptions

This KMP Shared Module Template is new, but KMP more broadly is a maturing technology with several large-scale migrations underway. In fact, KMP has matured enough to support mission critical applications at Google. Google Docs, for example, is now running KMP in production on iOS with runtime performance on par or better than before. Beyond Google, Stone’s 130 mobile developers are sharing over 50% of their code, allowing existing mobile teams to ship features approximately 40% faster to both Android and iOS.

KMP was designed for Android development

As always, we've designed the Shared Module Template with the needs of Android developer teams in mind. Making the KMP Shared Module Template part of the native Android Studio experience allows developers to efficiently add a shared module to an existing Android application and immediately start building shared business logic that leverages several KMP-ready Jetpack libraries including Room, SQLite, and DataStore to name just a few.

Come check it out at KotlinConf

Releasing Android Studio’s KMP Shared Module Template marks a significant step toward empowering Android development teams to innovate faster, to efficiently manage business logic, and to build high-quality applications with greater confidence. It means that Android developers can be responsible for the code that drives the business logic for every app across Android and iOS. We’re excited to bring Shared Module Template to KotlinConf in Copenhagen, May 21 - 23.

Get started with KMP Shared Module Template

To get started, you'll need the latest edition of Android Studio. In your Android project, the Shared Module Template is available within Android Studio when you create a new module. Click on “File” then “New” then “New Module” and finally “Kotlin Multiplatform Shared Module” and you are ready to add a KMP Shared Module to your Android app.

We appreciate any feedback on things you like or features you would like to see. If you find a bug, please report the issue. Remember to also follow us on X, LinkedIn, Blog, or YouTube for more Android development updates!

On-device GenAI APIs as part of ML Kit help you easily build with Gemini Nano

Android Developers — Tue, 20 May 2025 19:38:53 +0000

Posted by Caren Chang - Developer Relations Engineer, Chengji Yan - Software Engineer, Taj Darra - Product Manager

We are excited to announce a set of on-device GenAI APIs, as part of ML Kit, to help you integrate Gemini Nano in your Android apps.

To start, we are releasing 4 new APIs:

Summarization: to summarize articles and conversations
Proofreading: to polish short text
Rewriting: to reword text in different styles
Image Description: to provide short description for images

Key benefits of GenAI APIs

GenAI APIs are high level APIs that allow for easy integration, similar to existing ML Kit APIs. This means you can expect quality results out of the box without extra effort for prompt engineering or fine tuning for specific use cases.

GenAI APIs run on-device and thus provide the following benefits:

Input, inference, and output data is processed locally
Functionality remains the same without reliable internet connection
No additional cost incurred for each API call

To prevent misuse, we also added safety protection in various layers, including base model training, safety-aware LoRA fine-tuning, input and output classifiers and safety evaluations.

How GenAI APIs are built

There are 4 main components that make up each of the GenAI APIs.

Gemini Nano is the base model, as the foundation shared by all APIs.
Small API-specific LoRA adapter models are trained and deployed on top of the base model to further improve the quality for each API.
Optimized inference parameters (e.g. prompt, temperature, topK, batch size) are tuned for each API to guide the model in returning the best results.
An evaluation pipeline ensures quality in various datasets and attributes. This pipeline consists of: LLM raters, statistical metrics and human raters.

Together, these components make up the high-level GenAI APIs that simplify the effort needed to integrate Gemini Nano in your Android app.

Evaluating quality of GenAI APIs

For each API, we formulate a benchmark score based on the evaluation pipeline mentioned above. This score is based on attributes specific to a task. For example, when evaluating the summarization task, one of the attributes we look at is “grounding” (ie: factual consistency of generated summary with source content).

To provide out-of-box quality for GenAI APIs, we applied feature specific fine-tuning on top of the Gemini Nano base model. This resulted in an increase for the benchmark score of each API as shown below:

Use case in English	Gemini Nano Base Model	ML Kit GenAI API
Summarization	77.2	92.1
Proofreading	84.3	90.2
Rewriting	79.5	84.1
Image Description	86.9	92.3

In addition, this is a quick reference of how the APIs perform on a Pixel 9 Pro:

	Prefix Speed (input processing rate)	Decode Speed (output generation rate)
Text-to-text	510 tokens/second	11 tokens/second
Image-to-text	510 tokens/second + 0.8 seconds for image encoding	11 tokens/second

Sample usage

This is an example of implementing the GenAI Summarization API to get a one-bullet summary of an article:

val articleToSummarize = "We are excited to announce a set of on-device generative AI APIs..."

// Define task with desired input and output format
val summarizerOptions = SummarizerOptions.builder(context)
    .setInputType(InputType.ARTICLE)
    .setOutputType(OutputType.ONE_BULLET)
    .setLanguage(Language.ENGLISH)
    .build()
val summarizer = Summarization.getClient(summarizerOptions)

suspend fun prepareAndStartSummarization(context: Context) {
    // Check feature availability. Status will be one of the following: 
    // UNAVAILABLE, DOWNLOADABLE, DOWNLOADING, AVAILABLE
    val featureStatus = summarizer.checkFeatureStatus().await()

    if (featureStatus == FeatureStatus.DOWNLOADABLE) {
        // Download feature if necessary.
        // If downloadFeature is not called, the first inference request will 
        // also trigger the feature to be downloaded if it's not already
        // downloaded.
        summarizer.downloadFeature(object : DownloadCallback {
            override fun onDownloadStarted(bytesToDownload: Long) { }

            override fun onDownloadFailed(e: GenAiException) { }

            override fun onDownloadProgress(totalBytesDownloaded: Long) {}

            override fun onDownloadCompleted() {
                startSummarizationRequest(articleToSummarize, summarizer)
            }
        })    
    } else if (featureStatus == FeatureStatus.DOWNLOADING) {
        // Inference request will automatically run once feature is      
        // downloaded.
        // If Gemini Nano is already downloaded on the device, the   
        // feature-specific LoRA adapter model will be downloaded very  
        // quickly. However, if Gemini Nano is not already downloaded, 
        // the download process may take longer.
        startSummarizationRequest(articleToSummarize, summarizer)
    } else if (featureStatus == FeatureStatus.AVAILABLE) {
        startSummarizationRequest(articleToSummarize, summarizer)
    } 
}

fun startSummarizationRequest(text: String, summarizer: Summarizer) {
    // Create task request  
    val summarizationRequest = SummarizationRequest.builder(text).build()

    // Start summarization request with streaming response
    summarizer.runInference(summarizationRequest) { newText -> 
        // Show new text in UI
    }

    // You can also get a non-streaming response from the request
    // val summarizationResult = summarizer.runInference(summarizationRequest)
    // val summary = summarizationResult.get().summary
}

// Be sure to release the resource when no longer needed
// For example, on viewModel.onCleared() or activity.onDestroy()
summarizer.close()

For more examples of implementing the GenAI APIs, check out the official documentation and samples on GitHub:

Use cases

Here is some guidance on how to best use the current GenAI APIs:

For Summarization, consider:

Conversation messages or transcripts that involve 2 or more users

Articles or documents less than 4000 tokens (or about 3000 English words). Using the first few paragraphs for summarization is usually good enough to capture the most important information.

For Proofreading and Rewriting APIs, consider utilizing them during the content creation process for short content below 256 tokens to help with tasks such as:

Refining messages in a particular tone, such as more formal or more casual

Polishing personal notes for easier consumption later

For the Image Description API, consider it for:

Generating titles of images

Generating metadata for image search

Utilizing descriptions of images in use cases where the images themselves cannot be displayed, such as within a list of chat messages

Generating alternative text to help visually impaired users better understand content as a whole

GenAI API in production

Envision is an app that verbalizes the visual world to help people who are blind or have low vision lead more independent lives. A common use case in the app is for users to take a picture to have a document read out loud. Utilizing the GenAI Summarization API, Envision is now able to get a concise summary of a captured document. This significantly enhances the user experience by allowing them to quickly grasp the main points of documents and determine if a more detailed reading is desired, saving them time and effort.

Supported devices

GenAI APIs are available on Android devices using optimized MediaTek Dimensity, Qualcomm Snapdragon, and Google Tensor platforms through AICore. For a comprehensive list of devices that support GenAI APIs, refer to our official documentation.

Peacock built adaptively on Android to deliver great experiences across screens

Android Developers — Tue, 20 May 2025 19:38:22 +0000

Posted by Sa-ryong Kang and Miguel Montemayor - Developer Relations Engineers

Peacock is NBCUniversal’s streaming service app available in the US, offering culture-defining entertainment including live sports, exclusive original content, TV shows, and blockbuster movies. The app continues to evolve, becoming more than just a platform to watch content, but a hub of entertainment.

Today’s users are consuming entertainment on an increasingly wider array of device sizes and types, and in particular are moving towards mobile devices. Peacock has adopted Jetpack Compose to help with its journey in adapting to more screens and meeting users where they are.

Disclaimer: Peacock is available in the US only. This video will only be viewable to US viewers.

Adapting to more flexible form factors

The Peacock development team is focused on bringing the best experience to users, no matter what device they’re using or when they want to consume content. With an emerging trend from app users to watch more on mobile devices and large screens like foldables, the Peacock app needs to be able to adapt to different screen sizes. As more devices are introduced, the team needed to explore new solutions that make the most out of each unique display permutation.

The goal was to have the Peacock app to adapt to these new displays while continually offering high-quality entertainment without interruptions, like the stream reloading or visual errors. While thinking ahead, they also wanted to prepare and build a solution that was ready for Android XR as the entertainment landscape is shifting towards including more immersive experiences.

Building a future-proof experience with Jetpack Compose

In order to build a scalable solution that would help the Peacock app continue to evolve, the app was migrated to Jetpack Compose, Android’s toolkit for building scalable UI. One of the essential tools they used was the WindowSizeClass API, which helps developers create and test UI layouts for different size ranges. This API then allows the app to seamlessly switch between pre-set layouts as it reaches established viewport breakpoints for different window sizes.

The API was used in conjunction with Kotlin Coroutines and Flows to keep the UI state responsive as the window size changed. To test their work and fine tune edge case devices, Peacock used the Android Studio emulator to simulate a wide range of Android-based devices.

Jetpack Compose allowed the team to build adaptively, so now the Peacock app responds to a wide variety of screens while offering a seamless experience to Android users. “The app feels more native, more fluid, and more intuitive across all form factors,” said Diego Valente, Head of Mobile, Peacock and Global Streaming. “That means users can start watching on a smaller screen and continue instantly on a larger one when they unfold the device—no reloads, no friction. It just works.”

Preparing for immersive entertainment experiences

In building adaptive apps on Android, John Jelley, Senior Vice President, Product & UX, Peacock and Global Streaming, says Peacock has also laid the groundwork to quickly adapt to the Android XR platform: “Android XR builds on the same large screen principles, our investment here naturally extends to those emerging experiences with less developmental work.”

The team is excited about the prospect of features unlocked by Android XR, like Multiview for sports and TV, which enables users to watch multiple games or camera angles at once. By tailoring spatial windows to the user’s environment, the app could offer new ways for users to interact with contextual metadata like sports stats or actor information—all without ever interrupting their experience.

What's New in Jetpack Compose

Android Developers — Tue, 20 May 2025 19:37:48 +0000

Posted by Nick Butcher – Product Manager

At Google I/O 2025, we announced a host of features, performance, stability, libraries, and tools updates for Jetpack Compose, our recommended Android UI toolkit. With Compose you can build excellent apps that work across devices. Compose has matured a lot since it was first announced (at Google I/O 2019!) and we're now seeing 60% of the top 1,000 apps in the Play Store such as MAX and Google Drive use and love it.

New Features

Since I/O last year, Compose Bill of Materials (BOM) version 2025.05.01 adds new features such as:

Autofill support that lets users automatically insert previously entered personal information into text fields.
Auto-sizing text to smoothly adapt text size to a parent container size.
Visibility tracking for when you need high-performance information on a composable's position in its root container, screen, or window.
Animate bounds modifier for beautiful automatic animations of a Composable's position and size within a LookaheadScope.
Accessibility checks in tests that let you build a more accessible app UI through automated a11y testing.

LookaheadScope {
    Box(
        Modifier
            .animateBounds(this@LookaheadScope)
            .width(if(inRow) 100.dp else 150.dp)
            .background(..)
            .border(..)
    )
}

For more details on these features, read What’s new in the Jetpack Compose April ’25 release and check out these talks from Google I/O:

If you’re looking to try out new Compose functionality, the alpha BOM offers new features that we're working on including:

Pausable Composition (see below)
Updates to LazyLayout prefetch
Context Menus
New modifiers: onFirstVisible, onVisbilityChanged, contentType
New Lint checks for frequently changing values and elements that should be remembered in composition

Please try out the alpha features and provide feedback to help shape the future of Compose.

Material Expressive

At Google I/O, we unveiled Material Expressive, Material Design’s latest evolution that helps you make your products even more engaging and easier to use. It's a comprehensive addition of new components, styles, motion and customization options that help you to build beautiful rich UIs. The Material3 library in the latest alpha BOM contains many of the new expressive components for you to try out.

Learn more to start building with Material Expressive.

Adaptive layouts library

Developing adaptive apps across form factors including phones, foldables, tablets, desktop, cars and Android XR is now easier with the latest enhancements to the Compose adaptive layouts library. The stable 1.1 release adds support for predictive back gestures for smoother transitions and pane expansion for more flexible two pane layouts on larger screens. Furthermore, the 1.2 (alpha) release adds more flexibility for how panes are displayed, adding strategies for reflowing and levitating.

Compose Adaptive Layouts Updates in the Google Play app

Learn more about building adaptive android apps with Compose.

Performance

With each release of Jetpack Compose, we continue to prioritize performance improvements. The latest stable release includes significant rewrites and improvements to multiple sub-systems including semantics, focus and text optimizations. Best of all these are available to you simply by upgrading your Compose dependency; no code changes required.

Internal benchmark, run on a Pixel 3a

We continue to work on further performance improvements, notable changes in the latest alpha BOM include:

Pausable Composition allows compositions to be paused, and their work split up over several frames.
Background text prefetch enables text layout caches to be pre-warmed on a background thread, enabling faster text layout.
LazyLayout prefetch improvements enabling lazy layouts to be smarter about how much content to prefetch, taking advantage of pausable composition.

Together these improvements eliminate nearly all jank in an internal benchmark.

Stability

We've heard from you that upgrading your Compose dependency can be challenging, encountering bugs or behaviour changes that prevent you from staying on the latest version. We've invested significantly in improving the stability of Compose, working closely with the many Google app teams building with Compose to detect and prevent issues before they even make it to a release.

Google apps develop against and release with snapshot builds of Compose; as such, Compose is tested against the hundreds of thousands of Google app tests and any Compose issues are immediately actioned by our team. We have recently invested in increasing the cadence of updating these snapshots and now update them daily from Compose tip-of-tree, which means we’re receiving feedback faster, and are able to resolve issues long before they reach a public release of the library.

Jetpack Compose also relies on @Experimental annotations to mark APIs that are subject to change. We heard your feedback that some APIs have remained experimental for a long time, reducing your confidence in the stability of Compose. We have invested in stabilizing experimental APIs to provide you a more solid API surface, and reduced the number of experimental APIs by 32% in the last year.

We have also heard that it can be hard to debug Compose crashes when your own code does not appear in the stack trace. In the latest alpha BOM, we have added a new opt-in feature to provide more diagnostic information. Note that this does not currently work with minified builds and comes at a performance cost, so we recommend only using this feature in debug builds.

class App : Application() {
   override fun onCreate() {
        // Enable only for debug flavor to avoid perf impact in release
        Composer.setDiagnosticStackTraceEnabled(BuildConfig.DEBUG)
   }
}

Libraries

We know that to build great apps, you need Compose integration in the libraries that interact with your app's UI.

A core library that powers any Compose app is Navigation. You told us that you often encountered limitations when managing state hoisting and directly manipulating the back stack with the current Compose Navigation solution. We went back to the drawing-board and completely reimagined how a navigation library should integrate with the Compose mental model. We're excited to introduce Navigation 3, a new artifact designed to empower you with greater control and simplify complex navigation flows.

We're also investing in Compose support for CameraX and Media3, making it easier to integrate camera capture and video playback into your UI with Compose idiomatic components.

@Composable
private fun VideoPlayer(
    player: Player?, // from media3
    modifier: Modifier = Modifier
) {
    Box(modifier) {
        PlayerSurface(player) // from media3-ui-compose
        player?.let {
            // custom play-pause button UI
            val playPauseButtonState = rememberPlayPauseButtonState(it) // from media3-ui-compose
            MyPlayPauseButton(playPauseButtonState, Modifier.align(BottomEnd).padding(16.dp))
        }
    }
}

To learn more, see the media3 Compose documentation and the CameraX samples.

What’s new in Wear OS 6

Android Developers — Tue, 20 May 2025 19:03:24 +0000

Posted by Chiara Chiappini – Developer Relations Engineer

This year, we’re excited to introduce Wear OS 6: the most power-efficient and expressive version of Wear OS yet.

Wear OS 6 introduces the new design system we call Material 3 Expressive. It features a major refresh with visual and motion components designed to give users an experience with more personalization. The new design offers a great level of expression to meet user demand for experiences that are modern, relevant, and distinct. Material 3 Expressive is coming to Wear OS, Android, and all your favorite Google apps on these devices later this year.

The good news is that you don’t need to compromise battery for beauty: thanks to Wear OS platform optimizations, watches updating from Wear OS 5 to Wear OS 6 can see up to 10% improvement in battery life.¹

Wear OS 6 developer preview

Today we’re releasing the Developer Preview of Wear OS 6, the next version of Google’s smartwatch platform, based on Android 16.

Wear OS 6 brings a number of developer-facing changes, such as refining the always-on display experience. Check out what’s changed and try the new Wear OS 6 emulator to test your app for compatibility with the new platform version.

Material 3 Expressive on Wear OS

Some examples of Material 3 Expressive on Wear OS experiences

Material 3 Expressive for the watch is fully optimized for the round display. We recommend developers embrace the new design system in their apps and tiles. To help you adopt Material 3 Expressive in your app, we have begun releasing new design guidance for Wear OS, along with corresponding Figma design kits.

As a developer, you can get access the Material 3 Expressive on Wear OS using new Jetpack libraries:

Wear Compose Material 3 that provides components for apps.
Wear ProtoLayout Material 3 that provides components and layouts for tiles.

These two libraries provide implementations for the components catalog that adheres to the Material 3 Expressive design language.

Make it personal with richer color schemes using themes

Dynamic color theme updates colors of apps and Tiles

The Wear Compose Material 3 and Wear Protolayout Material 3 libraries provide updated and extended color schemes, typography, and shapes to bring both depth and variety to your designs. Additionally, your tiles now align with the system font by default (on Wear OS 6+ devices), offering a more cohesive experience on the watch.

Both libraries introduce dynamic color theming, which automatically generates a color theme for your app or tile to match the colors of the watch face of Pixel watches.

Make it more glanceable with new tile components

Tiles now support a new framework and a set of components that embrace the watch's circular form factor. These components make tiles more consistent and glanceable, so users can more easily take swift action on the information included in them.

We’ve introduced a 3-slot tile layout to improve visual consistency in the Tiles carousel. This layout includes a title slot, a main content slot, and a bottom slot, designed to work across a range of different screen sizes:

Some examples of Tiles with the 3-slot tile layout.

Highlight user actions and key information with components optimized for round screen

The new Wear OS Material 3 components automatically adapt to larger screen sizes, building on the Large Display support added as part of Wear OS 5. Additionally, components such as Buttons and Lists support shape morphing on apps.

The following sections highlight some of the most exciting changes to these components.

Embrace the round screen with the Edge Hugging Button

We introduced a new EdgeButton for apps and tiles with an iconic design pattern that maximizes the space within the circular form factor, hugs the edge of the screen, and comes in 4 standard sizes.

Screenshot representing an EdgeButton in a scrollable screen.

Fluid navigation through lists using new indicators

The new TransformingLazyColumn from the Foundation library makes expressive motion easy with motion that fluidly traces the edges of the display. Developers can customize the collapsing behavior of the list when scrolling to the top, bottom and both sides of the screen. For example, components like Cards can scale down as they are closer to the top of the screen.

TransformingLazyColumn allows content to collapse and change in size when approaching the edge of the screens

Material 3 Expressive also includes a ScrollIndicator that features a new visual and motion design to make it easier for users to visualize their progress through a list. The ScrollIndicator is displayed by default when you use a TransformingLazyColumn and ScreenScaffold.

ScrollIndicator

Lastly, you can now use segments with the new ProgressIndicator, which is now available as a full-screen component for apps and as a small-size component for both apps and tiles.

Example of a full-screen ProgressIndicator

To learn more about the new features and see the full list of updates, see the release notes of the latest beta release of the Wear Compose and Wear Protolayout libraries. Check out the migration guidance for apps and tiles on how to upgrade your existing apps, or try one of our codelabs if you want to start developing using Material 3 Expressive design.

Watch Faces

With Wear OS 6 we are launching updates for watch face developers:

New options for customizing the appearance of your watch face using version 4 of Watch Face Format, such as animated state transitions from ambient to interactive and photo watch faces.

A new API for building watch face marketplaces.

Learn more about what's new in Watch Face updates.

Look for more information about the general availability of Wear OS 6 later this year.

Library updates

ProtoLayout

Since our last major release, we've improved capabilities and the developer experience of the Tiles and ProtoLayout libraries to address feedback we received from developers. Some of these enhancements include:

New Kotlin-only protolayout-material3 library adds support for enhanced visuals: Lottie animations (in addition to the existing animation capabilities), more gradient types, and new arc line styles.
Developers can now write more idiomatic Kotlin, with APIs refined to better align with Jetpack Compose, including type-safe builders and an improved modifier syntax.

The example below shows how to display a layout with a text on a Tile using new enhancements:

// returns a LayoutElement for use in onTileRequest()
materialScope(context, requestParams.deviceConfiguration) {
    primaryLayout(
        mainSlot = {
            text(
                text = "Hello, World!".layoutString,
                typography = BODY_LARGE,
            )
        }
    )
}

For more information, see the migration instructions.

Credential Manager for Wear OS

The CredentialManager API is now available on Wear OS, starting with Google Pixel Watch devices running Wear OS 5.1. It introduces passkeys to Wear OS with a platform-standard authentication UI that is consistent with the experience on mobile.

The Credential Manager Jetpack library provides developers with a unified API that simplifies and centralizes their authentication implementation. Developers with an existing implementation on another form factor can use the same CredentialManager code, and most of the same supporting code to fulfill their Wear OS authentication workflow.

Credential Manager provides integration points for passkeys, passwords, and Sign in With Google, while also allowing you to keep your other authentication solutions as backups.

Users will benefit from a consistent, platform-standard authentication UI; the introduction of passkeys and other passwordless authentication methods, and the ability to authenticate without their phone nearby.

Check out the Authentication on Wear OS guidance to learn more.

Richer Wear Media Controls

New media controls for a Podcast

Devices that run Wear OS 5.1 or later support enhanced media controls. Users who listen to media content on phones and watches can now benefit from the following new media control features on their watch:

They can fast-forward and rewind while listening to podcasts.
They can access the playlist and controls such as shuffle, like, and repeat through a new menu.

Developers with an existing implementation of action buttons and playlist can benefit from this feature without additional effort. Check out how users will get more controls from your media app on a Google Pixel Watch device.

Start building for Wear OS 6 now

With these updates, there’s never been a better time to develop an app on Wear OS. These technical resources are a great place to learn more how to get started:

Earlier this year, we expanded our smartwatch offerings with Galaxy Watch for Kids, a unique, phone-free experience designed specifically for children. This launch gives families a new way to stay connected, allowing children to explore Wear OS independently with a dedicated smartwatch. Consult our developer guidance to create a Wear OS app for kids.

We’re looking forward to seeing the experiences that you build on Wear OS!

What’s new in Watch Faces

Android Developers — Tue, 20 May 2025 19:02:47 +0000

Posted by Garan Jenkin – Developer Relations Engineer

Wear OS has a thriving watch face ecosystem featuring a variety of designs that also aims to minimize battery impact. Developers have embraced the simplicity of creating watch faces using Watch Face Format – in the last year, the number of published watch faces using Watch Face Format has grown by over 180%^*.

Today, we’re continuing our investment and announcing version 4 of the Watch Face Format, available as part of Wear OS 6. These updates allow developers to express even greater levels of creativity through the new features we’ve added. And we’re supporting marketplaces, which gives flexibility and control to developers and more choice for users.

In this blog post we'll cover key new features, check out the documentation for more details of changes introduced in recent versions.

Supporting marketplaces with Watch Face Push

We’re also announcing a completely new API, the Watch Face Push API, aimed at developers who want to create their own watch face marketplaces.

Watch Face Push, available on devices running Wear OS 6 and above, works exclusively with watch faces that use the Watch Face Format watch faces.

We’ve partnered with well-known watch face developers – including Facer, TIMEFLIK, WatchMaker, Pujie, and Recreative – in designing this new API. We’re excited that all of these developers will be bringing their unique watch face experiences to Wear OS 6 using Watch Face Push.

From left to right, Facer, Recreative and TIMEFLIK watch faces have been developing marketplace apps to work with watches running Wear OS 6.

Watch faces managed and deployed using Watch Face Push are all written using Watch Face Format. Developers publish these watch faces in the same way as publishing through Google Play, though there are some additional checks the developer must make which are described in the Watch Face Push guidance.

The Watch Face Push API covers only the watch part of this typical marketplace system diagram - as the app developer, you have control and responsibility for the phone app and cloud components, as well as for building the Wear OS app using Watch Face Push. You’re also in control of the phone-watch communications, for which we recommend using the Data Layer APIs.

Adding Watch Face Push to your project

To start using Watch Face Push on Wear OS 6, include the following dependency in your Wear OS app:

// Ensure latest version is used by checking the repository
implementation("androidx.wear.watchface:watchface-push:1.3.0-alpha07")

Declare the necessary permission in your AndroidManifest.xml:

<uses-permission android:name="com.google.wear.permission.PUSH_WATCH_FACES" />

Obtain a Watch Face Push client:

val manager = WatchFacePushManagerFactory.createWatchFacePushManager(context)

You’re now ready to start using the Watch Face Push API, for example to list the watch faces you have already installed, or add a new watch face:

// List existing watch faces, installed by this app
val listResponse = manager.listWatchFaces()

// Add a watch face
manager.addWatchFace(watchFaceFileDescriptor, validationToken)

Understanding Watch Face Push

While the basics of the Watch Face Push API are easy to understand and access through the WatchFacePushManager interface, it’s important to consider several other factors when working with the API in practice to build an effective marketplace app, including:

How to build watch faces for use with Watch Face Push - Watch faces deployed using Watch Face Push require an additional validation step to be performed by the developer. Learn more about how to build watch faces for use with Watch Face Push, and to integrate Watch Face Push into your application.

Watch Face Slots - Each Watch Face Push-based application is able to install a limited number of watch faces at any given time, represented by a Slot. Learn more about how to work with and manage slots.

Default watch faces - The API allows for a default watch face to be installed when the app is installed. Learn more about how to build and include this default watch face.

Setting active watch faces - Through an additional permission, the app can set the active watch face. Learn about how to integrate this feature, as well as how to handle the different permission scenarios.

To learn more about using Watch Face Push, see the guidance and reference documentation.

Updates to Watch Face Format

Photos

Available from Watch Face Format v4

The new Photos element allows the watch face to contain user-selectable photos. The element supports both individual photos and a gallery of photos. For a gallery of photos, developers can choose whether the photos advance automatically or when the user taps the watch face.

Configuring photos through the watch Companion app

The user is able to select the photos of their choice through the companion app, making this a great way to include true personalization in your watch face. To use this feature, first add the necessary configuration:

<UserConfigurations>
  <PhotosConfiguration id="myPhoto" configType="SINGLE"/>
</UserConfigurations>

Then use the Photos element within any PartImage, in the same way as you would for an Image element:

<PartImage ...>
  <Photos source="[CONFIGURATION.myPhoto]"
          defaultImageResource="placeholder_photo"/>
</PartImage>

For details on how to support multiple photos, and how to configure the different change behaviors, refer to the Photos section of the guidance and reference, as well as the GitHub samples.

Transitions

Available from Watch Face Format v4

Watch Face Format now supports transitions when exiting and entering ambient mode.

State transition animation: Example using an overshoot effect in revealing the seconds digits

This is achieved through the existing Variant tag. For example, the hours and minutes in the above watch face are animated as follows:

<DigitalClock ...>
  <Variant mode="AMBIENT" target="x" value="100" interpolation="OVERSHOOT" />

   <!-- Rest of "hh:mm" clock definition here -->
</DigitalClock>

By default, the animation takes the full extent of allowed time for the transition. The new interpolation attribute controls the animation effect - in this case the use of OVERSHOOT adds a playful experience.

The seconds are implemented in a separate DigitalClock element, which shows the use of the new duration attribute:

<DigitalClock ...>
  <Variant mode="AMBIENT" target="alpha" value="0" duration="0.5"/>
   <!-- Rest of "ss" clock definition here -->
</DigitalClock>

The duration attribute takes a value between 0.0 and 1.0, with 1.0 representing the full extent of the allowed time. In this example, by using a value of 0.5, the seconds animation is quicker - taking half the allowed time, in comparison to the hours and minutes, which take the entire transition period.

For more details on using transitions, see the guidance documentation, as well as the reference documentation for Variant.

Color Transforms

Available from Watch Face Format v4

We’ve extended the usefulness of the Transform element by allowing color to be transformed on the majority of elements where it is an attribute, and also allowing tintColor to be transformed on Group and Part^* elements such as PartDraw and PartText.

The main exceptions to this addition are the clock elements, DigitalClock and AnalogClock, and also ComplicationSlot, which do not currently support Transform.

In addition to extending the list of transformable attributes to include colors, we’ve also added a handful of useful functions for manipulating color:

To see these in action, let’s consider an example.

The Weather data source provides the current UV index through [WEATHER.UV_INDEX]. When representing the UV index, these values are typically also assigned a color:

We want to represent this information as an Arc, not only showing the value, but also using the appropriate color. We can achieve this as follows:

<Arc centerX="0" centerY="0" height="420" width="420"
  startAngle="165" endAngle="165" direction="COUNTER_CLOCKWISE">
  <Transform target="endAngle"
    value="165 - 40 * (clamp(11, 0.0, 11.0) / 11.0)" />
  <Stroke thickness="20" color="#ffffff" cap="ROUND">
    <Transform target="color"
      value="extractColorFromWeightedColors(#97d700 #FCE300 #ff8200 #f65058 #9461c9, 3 3 2 3 1, false, clamp([WEATHER.UV_INDEX] + 0.5, 0.0, 12.0) / 12.0)" />
  </Stroke>
</Arc>

Let’s break this down:

The first Transform restricts the UV index to the range 0.0 to 11.0 and adjusts the sweep of the Arc according to that value.

The second Transform uses the new extractColorFromWeightedColors function.

The first argument is our list of colors

The second argument is a list of weights - you can see from the chart above that green covers 3 values, whereas orange only covers 2, so we use wei

Updates to the Android XR SDK: Introducing Developer Preview 2

Android Developers — Tue, 20 May 2025 19:02:20 +0000

Posted by Matthew McCullough – VP of Product Management, Android Developer

Since launching the Android XR SDK Developer Preview alongside Samsung, Qualcomm, and Unity last year, we’ve been blown away by all of the excitement we’ve been hearing from the broader Android community. Whether it's through coding live-streams or local Google Developer Group talks, it's been an outstanding experience participating in the community to build the future of XR together, and we're just getting started.

Today we’re excited to share an update to the Android XR SDK: Developer Preview 2, packed with new features and improvements to help you develop helpful and delightful immersive experiences with familiar Android APIs, tools and open standards created for XR.

At Google I/O, we have two technical sessions related to Android XR. The first is Building differentiated apps for Android XR with 3D content, which covers many features present in Jetpack SceneCore and ARCore for Jetpack XR. The future is now, with Compose and AI on Android XR covers creating XR-differentiated UI and our vision on the intersection of XR with cutting-edge AI capabilities.

What’s new in Developer Preview 2

Since the release of Developer Preview 1, we’ve been focused on making the APIs easier to use and adding new immersive Android XR features. Your feedback has helped us shape the development of the tools, SDKs, and the platform itself.

With the Jetpack XR SDK, you can now play back 180° and 360° videos, which can be stereoscopic by encoding with the MV-HEVC specification or by encoding view-frames adjacently. The MV-HEVC standard is optimized and designed for stereoscopic video, allowing your app to efficiently play back immersive videos at great quality. Apps built with Jetpack Compose for XR can use the SpatialExternalSurface composable to render media, including stereoscopic videos.

Using Jetpack Compose for XR, you can now also define layouts that adapt to different XR display configurations. For example, use a SubspaceModifier to specify the size of a Subspace as a percentage of the device’s recommended viewing size, so a panel effortlessly fills the space it's positioned in.

Material Design for XR now supports more component overrides for TopAppBar, AlertDialog, and ListDetailPaneScaffold, helping your large-screen enabled apps that use Material Design effortlessly adapt to the new world of XR.

An app adapts to XR using Material Design for XR with the new component overrides

In ARCore for Jetpack XR, you can now track hands after requesting the appropriate permissions. Hands are a collection of 26 posed hand joints that can be used to detect hand gestures and bring a whole new level of interaction to your Android XR apps:

Hands bring a natural input method to your Android XR experience.

For more guidance on developing apps for Android XR, check out our Android XR Fundamentals codelab, the updates to our Hello Android XR sample project, and a new version of JetStream with Android XR support.

The Android XR Emulator has also received updates to stability, support for AMD GPUs, and is now fully integrated within the Android Studio UI.

The Android XR Emulator is now integrated in Android Studio

Developers using Unity have already successfully created and ported existing games and apps to Android XR. Today, you can upgrade to the Pre-Release version 2 of the Unity OpenXR: Android XR package! This update adds many performance improvements such as support for Dynamic Refresh Rate, which optimizes your app’s performance and power consumption. Shaders made with Shader Graph now support SpaceWarp, making it easier to use SpaceWarp to reduce compute load on the device. Hand meshes are now exposed with occlusion, which enables realistic hand visualization.

Check out Unity’s improved Mixed Reality template for Android XR, which now includes support for occlusion and persistent anchors.

We recently launched Android XR Samples for Unity, which demonstrate capabilities on the Android XR platform such as hand tracking, plane tracking, face tracking, and passthrough.

Google’s open-source Unity samples demonstrate platform features and show how they’re implemented

The Firebase AI Logic for Unity is now in public preview! This makes it easy for you to integrate gen AI into your apps, enabling the creation of AI-powered experiences with Gemini and Android XR. The Firebase AI Logic fully supports Gemini's capabilities, including multimodal input and output, and bi-directional streaming for immersive conversational interfaces. Built with production readiness in mind, Firebase AI Logic is integrated with core Firebase services like App Check, Remote Config, and Cloud Storage for enhanced security, configurability, and data management. Learn more about this on the Firebase blog or go straight to the Gemini API using Vertex AI in Firebase SDK documentation to get started.

Continuing to build the future together

Our commitment to open standards continues with the glTF Interactivity specification, in collaboration with the Khronos Group. which will be supported in glTF models rendered by Jetpack XR later this year. Models using the glTF Interactivity specification are self-contained interactive assets that can have many pre-programmed behaviors, like rotating objects on a button press or changing the color of a material over time.

Android XR will be available first on Samsung’s Project Moohan, launching later this year. Soon after, our partners at XREAL will release the next Android XR device. Codenamed Project Aura, it’s a portable and tethered device that gives users access to their favorite Android apps, including those that have been built for XR. It will launch as a developer edition, specifically for you to begin creating and experimenting. The best news? With the familiar tools you use to build Android apps today, you can build for these devices too.

In-App Ratings and Reviews for TV

Android Developers — Tue, 20 May 2025 19:01:02 +0000

Posted by Paul Lammertsma – Developer Relations Engineer

Ratings and reviews are essential for developers, offering quantitative and qualitative feedback on user experiences. In 2022, we enhanced the granularity of this feedback by segmenting these insights by countries and form factors.

Now, we're extending the In-App Ratings and Reviews API to TV to allow developers to prompt users for ratings and reviews directly from Google TV.

Ratings and reviews on Google TV

Users can now see rating averages, browse reviews, and leave their own review directly from an app's store listing on Google TV.

Users can interact with in-app ratings and reviews on their TVs by doing the following:

Select ratings using the remote control D-pad.
Provide optional written reviews using Gboard’s on-screen voice input, or by easily typing from their phone.
Send mobile notifications to themselves to complete their TV app review directly on their phone.

Additionally, users can leave reviews for other form factors directly from their phone by simply selecting the device chip when submitting an app rating or writing a review.

We've already seen a considerable lift in app ratings on TV since bringing these changes to Google TV, and now, we're making it possible for developers to trigger a ratings prompt as well.

Before we look at the integration, let's first carefully consider the best time to request a review prompt. First, identify optimal moments within your app to request user feedback, ensuring prompts appear only when the UI is idle to prevent interruption of ongoing content.

In-App Review API

Integrating the Google Play In-App Review API is the same as on mobile and it's only a couple of method calls:

val manager = ReviewManagerFactory.create(context)
manager.requestReviewFlow().addOnCompleteListener { task ->
    if (task.isSuccessful) {
        // We got the ReviewInfo object
        val reviewInfo = task.result
        manager.launchReviewFlow(activity, reviewInfo)
    } else {
        // There was some problem, log or handle the error code
        @ReviewErrorCode val reviewErrorCode =
            (task.getException() as ReviewException).errorCode
    }
}

First, invoke requestReviewFlow() to obtain a ReviewInfo object which is used to launch the review flow. You must include an addOnCompleteListener() not just to obtain the ReviewInfo object, but also to monitor for any problems triggering this flow, such as the unavailability of Google Play on the device. Note that ReviewInfo does not offer any insights on whether or not a prompt appeared or which action the user took if a prompt did appear.

The challenge is to identify when to trigger launchReviewFlow(). Track user actions—identifying successful journeys and points where users encounter issues—so you can be confident they had a delightful experience in your app.

For this method, you may optionally also include an addOnCompleteListener() to ensure it resumes when the returned task is completed.

Note that due to throttling of how often users are presented with this prompt, there are no guarantees that the ratings dialog will appear when requesting to start this flow. For best practices, check this guide on when to request an in-app review.

Get started with In-App Reviews on Google TV

You can get a head start today by following these steps:

Identify successful journeys for users, like finishing a movie or TV show season.
Identify poor experiences that should be avoided, like buffering or playback errors.
Integrate the Google Play In-App Review API to trigger review requests at optimal moments within the user journey.
Test your integration by following the testing guide.
Publish your app and continuously monitor your ratings by device type in the Play Console.

We're confident this integration enables you to elevate your Google TV app ratings and empowers your users to share valuable feedback.

Engage users on Google TV with excellent TV apps

Android Developers — Tue, 20 May 2025 19:00:03 +0000

Posted by Shobana Radhakrishnan - Senior Director of Engineering, Google TV, and Paul Lammertsma - Developer Relations Engineer, Android

Over the past year, Google TV and Android TV achieved over 270 million monthly active devices, establishing one of the largest smart TV OS footprints. Building on this momentum, we are excited to share new platform features and developer tools designed to help you increase app engagement with our expanding user base.

Google TV with Gemini capabilities

Earlier this year, we announced that we’ll bring Gemini capabilities to Google TV, so users can speak more naturally and conversationally to find what to watch and get answers to complex questions.

After each movie or show search, our new voice assistant will suggest relevant content from your apps, significantly increasing the discoverability of your content.

Plus, users can easily ask questions about topics they're curious about and receive insightful answers with supporting videos.

We’re so excited to bring this helpful and delightful experience to users this fall.

Video Discovery API

Today, we’ve also opened partner enrollment for our Video Discovery API.

Video Discovery optimizes Resumption, Entitlements, and Recommendations across all Google TV form factors to enhance the end-user experience and boost app engagement.

Resumption: Partners can now easily display a user's paused video within the 'Continue Watching' row from the home screen. This row is a prime location that drives 60% of all user interactions on Google TV.

Entitlements: Video Discovery streamlines entitlement management, which matches app content to user eligibility. Users appreciate this because they can enjoy personalized recommendations without needing to manually update all their subscription details. This allows partners to connect with users across multiple discovery points on Google TV.

Recommendations: Video Discovery even highlights personalized content recommendations based on content that users watched inside apps.

Partners can begin incorporating the Video Discovery API today, starting with resumption and entitlement integrations. Check out g.co/tv/vda to learn more.

Jetpack Compose for TV

Last year, we launched Compose for TV 1.0 beta, which lets you build beautiful, adaptive UIs across Android, including Android TV OS.

Now, Compose for TV 1.0 is stable, and expands on the core and Material Compose libraries. We’ve even seen how the latest release of Compose significantly improves app startup within our internal benchmarking mobile sample, with roughly a 20% improvement compared with the March 2024 release. Because Compose for TV builds upon these libraries, apps built with Compose for TV should also see better app startup times.

New to building with Compose, and not sure where to start? Our updated Jetcaster audio streaming app sample demonstrates how to use Compose across form factors. It includes a dedicated module for playing podcasts on TV by combining separate view models with shared business logic.

Focus Management Codelab

We understand that focus management can be challenging at times. That’s why we’ve published a codelab that reviews how to set initial focus, prepare for unexpected focus traversal, and efficiently restore focus.

Memory Optimization Guide

We’ve released a comprehensive guide on memory optimization, including memory targets for low RAM devices as well. Combined with Android Studio's powerful memory profiler, this helps you understand when your app exceeds those limits and why.

In-App Ratings and Reviews

Moreover, app ratings and reviews are essential for developers, offering quantitative and qualitative feedback on user experiences. Now, we're extending the In-App Ratings and Reviews API to TV to allow developers to prompt users for ratings and reviews directly from Google TV. Check out our recent blog post detailing how to easily integrate the In-App Ratings and Reviews API.

Android 16 for TV

We're excited to announce the upcoming release of Android 16 for TV. Developers can begin using the latest beta today. With Android 16, TV developers can access several great features:

The MediaQualityManager allows developers to take control over selecting picture profiles.

Platform support for the Eclipsa Audio codec enables creators to use the IAMF spatial audio format. For ExoPlayer support that includes previous platform versions, see ExoPlayer's IAMF decoder module.

There are various improvements to media playback speed, consistency and efficiency, as well as HDMI-CEC reliability and performance optimizations for 64-bit kernels.

Additional APIs and user experiences from Android 16 are also available. We invite you to explore the complete list from the Android 16 for TV release notes.

What's next

We're incredibly excited to see how these announcements will optimize your development journey, and look forward to seeing the fantastic apps you'll launch on the platform!

Android’s Kotlin Multiplatform announcements at Google I/O and KotlinConf 25

Android Developers — Tue, 20 May 2025 18:59:31 +0000

Posted by Ben Trengrove - Developer Relations Engineer, Matt Dyor - Product Manager

Google I/O and KotlinConf 2025 bring a series of announcements on Android’s Kotlin and Kotlin Multiplatform efforts. Here’s what to watch out for:

Announcements from Google I/O 2025

Jetpack libraries

Our focus for Jetpack libraries and KMP is on sharing business logic across Android and iOS, but we have begun experimenting with web/WASM support.

We are adding KMP support to Jetpack libraries. Last year we started with Room, DataStore and Collection, which are now available in a stable release and recently we have added ViewModel, SavedState and Paging. The levels of support that our Jetpack libraries guarantee for each platform have been categorised into three tiers, with the top tier being for Android, iOS and JVM.

Tool improvements

We're developing new tools to help easily start using KMP in your app. With the KMP new module template in Android Studio Meerkat, you can add a new module to an existing app and share code to iOS and other supported KMP platforms.

In addition to KMP enhancements, Android Studio now supports Kotlin K2 mode for Android specific features requiring language support such as Live Edit, Compose Preview and many more.

How Google is using KMP

Last year, Google Workspace began experimenting with KMP, and this is now running in production in the Google Docs app on iOS. The app’s runtime performance is on par or better than before¹.

It’s been helpful to have an app at this scale test KMP out, because we’re able to identify issues and fix issues that benefit the KMP developer community.

For example, we've upgraded the Kotlin Native compiler to LLVM 16 and contributed a more efficient garbage collector and string implementation. We're also bringing the static analysis power of Android Lint to Kotlin targets and ensuring a unified Gradle DSL for both AGP and KGP to improve the plugin management experience.

New guidance

We're providing comprehensive guidance in the form of two new codelabs: Getting started with Kotlin Multiplatform and Migrating your Room database to KMP, to help you get from standalone Android and iOS apps to shared business logic.

Kotlin Improvements

Kotlin Symbol Processing (KSP2) is stable to better support new Kotlin language features and deliver better performance. It is easier to integrate with build systems, is thread-safe, and has better support for debugging annotation processors. In contrast to KSP1, KSP2 has much better compatibility across different Kotlin versions. The rewritten command line interface also becomes significantly easier to use as it is now a standalone program instead of a compiler plugin.

KotlinConf 2025

Google team members are presenting a number of talks at KotlinConf spanning multiple topics:

Talks

Deploying KMP at Google Workspace by Jason Parachoniak, Troels Lund, and Johan Bay from the Workspace team discusses the challenges and solutions, including bugs and performance optimizations, encountered when launching Kotlin Multiplatform at Google Workspace, offering comparisons to ObjectiveC and a Q&A. (Technical Session)

The Life and Death of a Kotlin/Native Object by Troels Lund offers a high-level explanation of the Kotlin/Native runtime's inner workings concerning object instantiation, memory management, and disposal. (Technical Session)

APIs: How Hard Can They Be? presented by Aurimas Liutikas and Alan Viverette from the Jetpack team delves into the lifecycle of API design, review processes, and evolution within AndroidX libraries, particularly considering KMP and related tools. (Technical Session)

Project Sparkles: How Compose for Desktop is changing Android Studio and IntelliJ with Chris Sinco and Sebastiano Poggi from the Android Studio team introduces the initiative ('Project Sparkles') aiming to modernize Android Studio and IntelliJ UIs using Compose for Desktop, covering goals, examples, and collaborations. (Technical Session)

JSpecify: Java Nullness Annotations and Kotlin presented by David Baker explains the significance and workings of JSpecify's standard Java nullness annotations for enhancing Kotlin's interoperability with Java libraries. (Lightning Session)

Lessons learned decoupling Architecture Components from platform specific code features Jeremy Woods and Marcello Galhardo from the Jetpack team sharing insights from the Android team on decoupling core components like SavedState and System Back from platform specifics to create common APIs. (Technical Session)

KotlinConf’s Closing Panel, a regular staple of the conference, returns, featuring Jeffrey van Gogh as Google’s representative on the panel. (Panel)

Live Workshops

If you are at KotlinConf in person, we will have guided live workshops with our new codelabs from above.

The codelab Get Started With Kotlin Multiplatform for Shared Business Logic, offered by Matt Dyor, Dustin Lam, and Tomáš Mlynarič, provides hands-on guidance for extracting business logic from native Android and iOS apps into a shared KMP module.

The codelab Migrating Room to Room KMP, also led by Matt Dyor, and Dustin Lam, Tomáš Mlynarič, demonstrates the process of migrating an existing Room database implementation to Room KMP within a shared module.

We love engaging with the Kotlin community. If you are attending KotlinConf, we hope you get a chance to check out our booth, with opportunities to chat with our engineers, get your questions answered, and learn more about how you can leverage Kotlin and KMP.

5 Ways to Customize Your WordPress Post Embeds

Thoriq Firdaus — Fri, 16 May 2025 13:00:49 +0000

WordPress introduced post embeds in version 4.4, allowing you to easily share and display WordPress posts from one site to another. When you paste a link to a WordPress post, it automatically appears as a styled preview with the title, excerpt, and featured image.

While this feature makes sharing content simple, the default look might not always match your website’s style or layout, as we can see below.

Default WordPress post embeds look

Fortunately, WordPress provides several ways to customize these embeds to better fit your design. In this article, we’ll explore different ways to tweak and personalize WordPress post embeds, so they blend seamlessly with your site.

1. Customizing the Styles

You can easily change the embed’s appearance to better match your website’s theme by adding a custom CSS file with the enqueue_embed_scripts hook, which ensures it’s loaded when the embed is displayed. You can add it in your theme’s functions.php file, for example:

add_action( 'enqueue_embed_scripts', function () {
    wp_enqueue_style(
        'my-theme-embed',
        get_theme_file_uri( 'embed.css' ),
        ['wp-embed-template']
    );
} );

This function tells WordPress to load your custom embed.css file when rendering an embedded post. Now, you can define your own styles in css/embed.css to modify the look of the embed. For example, you can adjust the typography, colors, or layout with CSS like this:

.wp-embed {
    background-color: #f9f9f9;
    border: 1px solid #eee;
    border-radius: 8px;
}

.wp-embed-featured-image img {
    border-radius: 5px;
}

With these changes, your WordPress post embeds will have a unique style that aligns with your site’s design, as shown below:

2. Customizing the Image

By default, WordPress post embeds use a predefined image size for the featured image. However, you can customize this to better match your design by specifying a different image size.

For example, if you want the embed image to be a perfect square but don’t have a square image size set up yet, you can define one using the following code in your theme’s functions.php file. This code will create a new image size called embed-square, which crops images precisely to 300×300 pixels.

add_action( 'after_setup_theme', function () {
    add_image_size( 'embed-square', 300, 300, true );
} );

Then, use the embed_thumbnail_image_size hook

add_filter( 'embed_thumbnail_image_size', function () {
    return 'embed-square';
} );

If you’ve already uploaded images before adding this code, WordPress won’t automatically generate the new embed-square size for them. To fix this, you can use the Regenerate Thumbnails plugin. This ensures that all your older featured images are available in the new size and display correctly in post embeds.

Now, your WordPress post embeds will now use the embed-square image size, as shown below:

3. Customizing the Excerpt

The post embeds also display an excerpt of the post content. However, the default length may not always fit your design or readability preferences. Fortunately, you can control how much text is shown by adjusting the excerpt length by using the excerpt_length

For example, if you want to shorten the excerpt to 18 words specifically for embeds, you can use the following code in your theme’s functions.php file:

add_filter( 'excerpt_length', function ($length) {
    return is_embed() ? 18 : $length;
} );

This code checks if the content is being displayed in an embed and, if so, limits the excerpt to 18 words. Otherwise, it keeps the default excerpt length, as shown below.

Experiment with different word counts to find the right balance in your content.

4. Adding Custom Content

By default, WordPress post embeds display basic information like the title, excerpt, and featured image. However, you might want to include additional details, such as the post’s updated date, to provide more context.

To do so, you can use the embed_content. In our case, we can add the following code in the functions.php file to display the post’s updated date:

add_action( 'embed_content', function () {
    if ( ! is_single() ) {
        return;
    }

    $updated_time = get_the_modified_time( 'U' );
    $published_time = get_the_time( 'U' );

    if ( $updated_time > $published_time ) {
        $time = sprintf(
            '<time datetime="%s">%s</time>',
            esc_attr( get_the_modified_date( 'Y-m-d' ) ),
            esc_html( get_the_modified_date() )
        );

        printf(
            '<p class="wp-embed-updated-on">%s</p>',
            sprintf(
                esc_html__( 'Updated on %s', 'devblog' ),
                $time
            )
        );
    }
} );

Now, the post embeds will display the updated date after the content, as shown below:

Displaying the updated date is helpful for readers to know if the content has been recently refreshed. This is especially useful for articles with time-sensitive information, tutorials, or news posts that may change over time.

5. Overriding Embed Templates

By default, WordPress uses a single template file called embed.php to display embedded content for all post types, including blog posts, pages, and custom post types. If you want to change how embedded content looks across your site, you can create a custom embed.php file inside your theme folder.

Additionally, WordPress lets you customize embeds for specific post types. For example, if you have a custom post type called “product” and want its embed to show extra details like price and availability without affecting other embeds you can create an embed-product.php file in your theme folder and customize it as needed.

<?php get_header( 'embed' ); ?>
<?php $product = wc_get_product( get_the_ID() ) ?>
<div id="embed-product-<?php the_ID(); ?>" <?php post_class("wp-embed") ?>>
    <div class="embed-product-image">
        <?php the_post_thumbnail( 'embed-square' ); ?>
    </div>
    <div class="embed-product-details">
        <header class="embed-product-header">
            <h3 class="embed-product-title"><?php the_title(); ?></h3>
        </header>
        <div class="embed-product-content">
            <?php the_excerpt(); ?>
            <p><strong>Price</strong>: <?php echo number_format($product->get_regular_price()); ?></p>
            <p><button>Buy Now</button></p>
        </div>
    </div>
</div>
<?php get_footer( 'embed' ); ?>

Now, whenever a product post is embedded, WordPress will use this template instead of the default one.

Bonus:

Disable Post Embed for Specific Post Types

While post embeds are a useful feature for sharing content, you might want to disable them for specific posts or post types. For example, you may have private content that you don’t want to be embedded on other sites.

To disable post embeds for a specific post, you can use the embed_oembed_html filter to return an empty string.

Here’s an example of how you can disable post embeds for page post type.

add_filter( 'embed_oembed_html', function ( $html, $url, $attr, $post_id ) {
    if ( get_post_type( $post_id ) === 'page' ) {
        return '';
    }

    return $html;
}, 10, 4 );

Wrapping up

WordPress post embeds make it easy to share content between websites. In this article, we explored several ways to customize how these embeds look, so they match your site’s design and include extra details for your readers. Now, you can try these techniques to create embeds that look better and make your content more engaging.

Secure Secret Management with 1Password CLI

Thoriq Firdaus — Thu, 15 May 2025 13:00:37 +0000

As developers, we often deal with sensitive data like API keys, SSH credentials, database passwords, and other secrets. Keeping them secure while ensuring easy access across different projects can be a challenge.

This is where 1Password‘s’ CLI comes in.

1Password CLI is a command-line tool that allows you to securely access and manage your 1Password vault without leaving the terminal. Instead of manually copying and pasting secrets, which can be tedious and risky, you can fetch credentials programmatically, automate authentication workflows, and integrate secrets management into your development processes.

In this article, we’ll explore how to install, configure, and use 1Password CLI to streamline your workflow while keeping your credentials secure.

Getting Started

If you’re on macOS or Linux, the easiest way to install 1Password CLI is using Homebrew:

brew install 1password-cli

If you’re on Windows, I recommend referring to the official 1Password CLI documentation for installation instructions.

For Windows and Linux, follow the official 1Password CLI installation guide to get the appropriate setup for your system.

Once installed, go to Settings… > Developer in the 1Password app, and check Integrate with 1Password CLI.

Then, sign in through the Terminal with the following command and select the 1Password account you want to sign in to:

op signin

Now, you’re ready to securely access and manage secrets without exposing them in plain text.

Command-Line Secret Management

When running commands that require authentication, manually copying and pasting credentials can be both tedious and insecure. With 1Password CLI, you can retrieve secrets dynamically using the op read command and the Secret References.

To get the Secret Reference, you can click on the dropdown arrow of the value within the item you’d like to refer to in 1Password.

Then pass it in the command that requires the secrets. For example, to authenticate with doctl using the DigitalOcean API token, you can run:

doctl auth init --access-token $(op read op://Internet/d439ada/token)

Environment Variables Integration

Another way you can use 1Password CLI is by setting the secrets as environment variables. This is useful when working with multiple secrets or when you need to pass them to a script or a program.

If you’re using Chromatic to test your UI components, you can set the CHROMATIC_PROJECT_TOKEN as an environment variable using the op read command:

#!/bin/bash
export NPM_TOKEN=$(op read op://Internet/d439ada/npm_token)
export CHROMATIC_PROJECT_TOKEN=$(op read op://Internet/d439ada/chromatic_token)

// Install the dependencies, including the private ones that require NPM_TOKEN.
npm install

// Chormatic will automatically use the CHROMATIC_PROJECT_TOKEN.
// @see https://www.chromatic.com/docs/cli/#continuous-integration
npx chromatic

Then, you can run the script using the op run command, as follows:

op run -- bash chormatic.sh

Shell Plugin Extensions

To make it even more seamless, you can use the Shell Plugins to integrate 1Password with popular third-party apps such as Github CLI, Docker, DigitalOcean CLI, AWS, HuggingFace, OpenAI, and many more.

In this example, we are going to try to integrate it with the Github CLI. To do so, we can run:

op plugin init gh

You’ll be prompted to import your GitHub credentials into 1Password or select an existing 1Password item where your credentials are saved. In this case, since we’ve already saved the GitHub credentials in 1Password, we can select the existing item.

Then, it will ask you the scope where the selected credentials can be used. In this case, we’d select it to use it globally so that we can use it across different repositories.

If this is your first time installing a shell plugin, you’ll need to add the source command to your RC file or shell profile to persist the plugin beyond the current terminal session. For example:

echo "source /Users/jondoe/.config/op/plugins.sh" >> ~/.zshrc && source ~/.zshrc

That’s it for the setup! Now, you can use the gh command to interact with GitHub without exposing your credentials in plain text. To test it out you can run the gh auth status.

Conclusion

1Password CLI is a powerful tool that allows you to securely access and manage your secrets from the Terminal. With a little bit of setup, you can streamline your workflow and integrate secrets management into your development processes with other apps without exposing your credentials in plain text. If you haven’t tried it yet, I recommend giving it a try to make your development workflow more secure and efficient.

10+ Best Burner Email Providers

Gina Mark — Thu, 15 May 2025 10:00:39 +0000

A burner email, also known as a disposable email, is a temporary address that is used in place of your primary email. Think of it as a protective shield for your real email, keeping it safe from unwanted spam and potential data breaches.

Why Would You Need a Burner Email?

Let’s be honest – we’ve all been there. You want to download that cool PDF guide or try out a new app, but they’re asking for your email address. Sure, you could use your main email, but do you really want to deal with the inevitable flood of marketing emails that follows?

Is Burner email free?

Yes, many burner email services offer free basic features. Services like 10 Minute Mail, Temp-Mail, and Guerrilla Mail are completely free. However, premium services like SimpleLogin and Burner Mail offer additional features like custom domains, unlimited aliases, and better privacy protection for a subscription fee.

Can burner emails be traced?

While burner emails provide a layer of anonymity, they aren’t completely untraceable. The level of privacy depends on the service provider and their logging policies. Premium services often offer better privacy features and fewer logs. For maximum privacy, consider using a VPN alongside your burner email.

How long does a burner email last?

The duration varies by service. Some temporary emails last for just 10 minutes (like 10 Minute Mail), others for 24 hours, and some premium services let you keep the address as long as you want. Many services also allow you to extend the duration or delete the address manually when you’re done.

Can I receive attachments with burner emails?

Most burner email services support receiving attachments, but there are usually size limitations. Free services typically have stricter limits (often 10MB or less), while paid services may offer larger attachment capabilities. Always check the service’s limitations before using it for receiving important files.

Are burner emails legal?

Yes, using burner emails is legal for legitimate purposes like protecting your privacy or reducing spam. However, using them for fraud, harassment, or other malicious activities is illegal. Always follow the service provider’s terms of use and local laws.

Can I send emails from a burner address?

This depends on the service. Some basic free services only allow receiving emails, while others provide full sending capabilities. Premium services typically offer more reliable sending features and may even let you reply from different aliases.

What happens to emails after the burner address expires?

When a burner email expires, any emails sent to that address will typically bounce back to the sender. Most services automatically delete all associated data and messages for privacy reasons. Some premium services may offer message archiving options before expiration.
