Last summer #WeArePlay went on a virtual tour of the U.S. to spotlight the stories of app and game founders from every state, and earlier this year we visited India sharing stories from across the country. Today, we’re continuing our tour across the world with our next stop: Europe. From an app increasing independence for the elderly to a game for children with neurodevelopmental disorders, meet the founders of 126 apps and games companies building growing businesses on Google Play.
Let’s take a quick road trip across the region, with stories of founders that were inspired to create their company to help others around them.
Geert, cofounder of Cubigo
Increasing independence for elderly people
First up is Geert from Belgium, who is the founder of Cubigo. When Geert’s grandmother moved into a nursing home, managing her care felt overwhelming so he used his experience from working in tech to create his app. It’s aimed at elderly people - they can use it to book taxis, days out, order food, schedule appointments and message friends. Family and nursing staff can also stay updated with their plans and activities, so they can provide better assistance. His aim is to give elderly people independence, and Geert hopes Cubigo will become a global player in senior care. Read more stories from Belgium.
Zafer and Sercan, co-founders of Otsimo
Games designed for children with neurodevelopmental disorders
Next up are friends and co-founders Zafer and Sercan from Turkey, who co-founded gaming company Otsimo. As a teen, Zafer got inspiration to create mobile tools for kids with learning difficulties by seeing his autistic brother enjoy playing on his phone. Fast forward to his college years, Zafer and his course mate Sercan made a series of apps aimed at children with delayed speech and developmental disorders. The first, created alongside special needs experts, was Otsimo | Special Education which can be tailored to the individual's requirements. Their apps use voice recognition and machine learning to help children improve their speech, cognitive and social skills, with rewards and stickers to keep it fun. The Otsimo team have just launched a fully customizable Augmentative and Alternative Communication (AAC) app for non-verbal people of all ages. Read more stories from Turkey.
Maxence and Oxana, co-founders of Appsent
Making home management and cleaning easier for everyone
Last but not least, we have Maxence and Oxana from France, co-founders of Appsent. Maxence and Oxana struggled to keep their house clean when they were both working from home. Sweepy is their solution – it’s a smart home cleaning schedule that assigns household tasks on particular days and for particular people. The couple are really proud that their app has been downloaded by lots of people with autism and ADHD, who tell them that it helps them to manage their homes. They are now developing a points and rewards feature, to try to encourage children to get involved in the housework too. Read more stories from France.

With today's Android 14 Beta 3 release, we're continuing into the next phase of the Android development cycle. It builds upon our core themes of privacy, security, performance, developer productivity, and user customization while continuing to improve the large-screen device experience on tablets, foldables, and more.
Beta 3 takes Android 14 to Platform Stability, which means that the developer APIs and all app-facing behaviors are now final for you to review and integrate into your apps. Thank you for all of your continued feedback in getting us to this milestone.
With Platform Stability in Beta 3, you can confidently develop and release any necessary compatibility updates. Please start your final compatibility testing now and prepare to publish any necessary updates so you can get valuable feedback during the remainder of the beta releases. This will help ensure a smooth app experience ahead of the final release of Android 14 later this year.
If you develop an SDK, library, tool, or game engine, it's even more important to be testing now so you can release your compatible updates as soon as possible to prevent your downstream app and game developers from being blocked with compatibility issues. Also, when you've released a compatible update, please make sure to let your developers know.
App Compatibility
Each release of Android contains changes to the platform that improve privacy, security, and the overall user experience. These changes can affect your apps. Testing your app involves installing your production app onto a device running Android 14 Beta 3; you can use Google Play or other means. Work through all the app's flows and look for functional or UI issues. Review the behavior changes to focus your testing. Changes that may impact your app include:
Users can now grant partial access to their media library when your app requests any of the visual media permissions (READ_MEDIA_IMAGES or READ_MEDIA_VIDEO) introduced in Android 13 (API level 33). When your app moves to the background, or when the user actively kills your app, the system treats these as one-time-permissions and eventually denies them. If your app is following permissions best practices, this change shouldn't break your app. Android 14 introduces the READ_MEDIA_VISUAL_USER_SELECTED permission to help apps better support the new changes. For a more seamless user experience, we recommend that you consider using the photo picker which provides a safe way for users to grant your app access to selected images and videos that does not require any permissions.
To enhance user privacy, Android 14 increases the number of places where the system shows the information you have declared in the Play Console Form. For some permissions, the system runtime permission dialog now includes a clickable section that highlights your app's data sharing practices. This section of the system dialog includes information, such as why your app may decide to share data with third parties, and links users to where they can control your app's data access. We encourage you to review your app's location data sharing policies and take a moment to make any applicable updates to your app's Google Play Data safety section.
Please review the behavior changes section to see all of the changes that may impact the compatibility of your app or game. If you find any issues with libraries and SDKs in your app, try updating to the latest library or SDK version, reaching out to the developer for help if necessary.
A few of the changes Android 14 makes to refresh core libraries to align with features in the latest OpenJDK LTS releases can affect app compatibility, including changes to regular expressions, UUID handling, and issues involving ProGuard and the addition of java.lang.ClassValue.
Today's Beta 3 release has everything you need to try the Android 14 features, test your apps, and give us feedback. For testing your app with tablets and foldables, you can test with devices from our partners, but the easiest way to get started is using the 64-bit Android Emulator system images for the Pixel Tablet or Pixel Fold configurations found in the latest preview of the Android Studio SDK Manager. You can also enroll any supported Pixel device here, including the new Pixel 7a, to get this and future Android 14 Beta and feature drop Beta updates over-the-air.
For the best development experience with Android 14, we recommend that you use the latest release of Android Studio Hedgehog. Once you’re set up, here are some of the things you should do:
Try the new features and APIs. Report issues in our tracker on the feedback page.
Test your current app for compatibility – learn whether your app is affected by default behavior changes in Android 14. Install your app onto a device or emulator running Android 14 and extensively test it.
Test your app with opt-in changes – Android 14 has opt-in behavior changes that only affect your app when it’s targeting the new platform. It’s important to understand and assess these changes early. To make it easier to test, you can toggle the changes on and off individually.
We’ll update the beta system images regularly throughout the Android 14 release cycle.
If you are already enrolled in the Android 14 Beta program and your device is supported, Beta 3 will be made available to you as an Over The Air update without taking any additional action.

Last year, we introduced new capabilities for subscriptions on Google Play, giving you more flexibility and control when it comes to growing and retaining your subscribers. The enhanced developer experience enabled by the monetization.subscriptions APIs, separates your subscription products - what you sell - from how yousell them, allowing you to configure multiple base plans and offers for each subscription. The new model is designed to reduce the complexity and overhead of managing your product configuration - this means:
The subscription now defines the benefits and other metadata for the product you are selling, regardless of how the user pays.
Each base plan within a subscription defines the base price for a specific billing period and plan renewal type.
In addition to auto-renewing plans, you can sell prepaid plans that allow users access to pay a fixed amount of time, and then top-up as desired. With prepaid plans, reach users in regions where pay-as-you-go is standard or provide an alternative for users not ready to purchase an auto-renewing plan.
Offers build on the base plan, making it easier to define alternative pricing for eligible users throughout the monetization lifecycle. They can be used to acquire new subscribers, incentivize upgrades, or retain existing subscribers.
Monetization.subscriptions APIs will replace InAppProducts API for subscription catalog management
Starting on January 1, 2024, all new apps must use monetization.subscriptions APIs for managing your subscriptions catalog. Existing apps will have until May 1, 2024 to migrate to the new monetization.subscriptions APIs, at which point support for using the InAppProducts API for managing your subscriptions catalog will end completely.
Starting this month, if we detect that your app has used the InAppProducts API to manage your subscriptions within the last 7 days, you will start seeing a reminder in Play Console to migrate over to monetization.subscriptions APIs.
Additionally, if your app is not using the latest version of Play Billing Library, you’ll need to upgrade to version 5.0 or later before November of this year in order to publish updates to your app.
If you continue to use the InAppProduct API while support is still available, the subscription SKUs you create will be automatically converted into the new model following the backward compatible structure represented below with limited access to new features. Learn more about converted subscriptions here.
New model separates your subscription products – what you sell – from how you sell them.
No changes to selling in-app items with the InAppProducts API
This deprecation will only impact the InAppProducts API when used to manage your subscription product catalog in Play Console. All apps can continue using the InAppProducts API to manage one-time products. The Play Billing Library and Subscription Purchase APIs will not be impacted. Note that both InAppProducts API and monetization.subscriptions APIs are for managing your subscription catalog on Play from your backend, and should not be called directly as part of any in-app flows.
Start your migration to the monetization.subscriptions APIs
If you use the Google Play Developer API client libraries - available for Java, Python, and other popular languages - we recommend upgrading to the latest versions, which already include the monetization.subscriptions APIs. Base plans can be managed with the monetization.subscription.basePlans API, and introductory pricing and free trials can be managed as offers with the monetization.subscriptions.basePlans.offers API.

In our latest #WeArePlay film, we’re spotlighting Tessa and Saasha - best friends turned co-founders of Olio. They’ve been on a mission to help people reduce waste by encouraging communities to share, sell or give-away what they no longer need - from leftover food to household items. The app now helps millions take one big step closer to living in a zero waste world.
Growing up on a farm, Tessa quickly learned how much hard work goes into producing food. Meanwhile, Saasha spent her childhood helping her family make ends meet through scavenging items that others threw away. When they eventually met in college, they bonded over their passion to help to save the environment through recycling and reducing waste.
But it wasn’t until Tessa was one day moving countries when the idea for Olio came - she couldn’t pack leftover food in air-freight, and couldn’t easily find anyone to take it. Feeling like this was a missed opportunity, she told Saasha about the idea for a food-sharing app. Saasha instantly knew she wanted to help make this app a reality, and so Olio was born. Tessa believes that “if no one else is taking action then we have to take action”.
Originally developed to encourage people to give away their surplus food, over time Olio has evolved so that people can give away any items that could have a second life. It’s now used in 62 countries, and Olio also partners with supermarkets and restaurants with the help of Food Waste Heroes - volunteers who collect and redistribute surplus food – saving an estimated 1 million meals per week. Looking to the future, Saasha says their ambition is “to create a world in which sharing becomes the new normal”.

Google I/O 2023 was filled with exciting updates and announcements. Modern Android Development (MAD) is all about making Android app development faster and easier! By creating libraries, tools and guidance to speed up your flow and help you write safer, better code so that you can focus on building amazing experiences.
Here are our top three announcements from Google I/O 2023:
#1 Get your development questions answered with Studio Bot
One of the announcements we’re most excited about is Studio Bot, an experimental new AI powered coding assistant, right in your IDE. You can ask it questions or use it to help fix errors — all without ever having to leave Android Studio or upload your source code.
Studio Bot is in its very early days, and is currently available for developers in the US. Download Android Studio canary to try it out and help it improve.
#2 Jetpack Compose has improvements for flow layouts, new Material components, and more
There have also been large performance improvements to the modifier system, with more updates still in the works. For text alone, this update resulted in an average 22% performance gain that can be seen in the latest alpha release, and these improvements apply across the board. To get these benefits in your app, all you have to do is update your Compose version!
You can now also use Jetpack Compose to build home screen widgets with the Glance library and TV apps with Compose for TV.
Since the official Kotlin for Android support announcement in 2017, we’ve continued to make improvements to helping you develop with Kotlin. Six years later, we are continuing to invest in improvements for Kotlin.
Firstly, we are collaborating with JetBrains on the new K2 compiler which is already showing significant improvements in compilation speed. We are actively working on integration into our tools such as Android Studio, Android Lint, KSP, Compose and more, and leveraging Google’s large Kotlin codebases to verify compatibility of the new compiler.
In addition, we now recommend using Kotlin for your build scripts and version catalogs. With Kotlin in your build and in your UI with Compose, you can now use Kotlin everywhere, throughout your app.
Posted by Jolanda Verhoef, Android Developer Relations Engineer
It has been almost two years since we launched the first stable version of Jetpack Compose, and since then, we’ve seen its adoption and feature set grow spectacularly. Whether you write an application for smartphones, foldables, tablets, ChromeOS devices, smartwatches, or TVs, Compose has got you covered! We recommend you to use Compose for all new Wear OS, phone and large-screen apps. With new tooling and library features, extended Material Design 3, large screen, and Wear OS support, and alpha versions of Compose for homescreen widgets and TV… This is an exciting time!
Compose in the community
In the last year, we’ve seen many companies investigating and choosing Compose to build new features and migrate screens in their production applications. 24% of the top 1000 apps on Google Play have already chosen to adopt Compose! For example, Dropbox engineers told us that they rewrote their search experience in Compose in just a few weeks, which was 40% less time than anticipated, and less than half the time it took the team to build the feature on iOS. They also shared that they were interested in adopting Compose “because of its first-class support for design systems and tooling support”. Our Google Drive team cut their development time nearly in half when using Compose combined with architecture improvements.
It’s great to see how these teams experience faster development cycles, and also feel their UI code is more testable. Inspired? Start by reading our guide How to Adopt Compose for your Team, which outlines how and where to start, and shows the areas of development where Compose can bring huge added value.
Library features & development
Since we released the first Compose Bill of Materials in October last year, we’ve been working on new features, bug fixes, performance improvements, and bringing Compose to everywhere you build UI: phones, tablets, foldables, watches, TV, and your home screen. You can find all changes in the May 2023 release and the latest alpha versions of the Compose libraries.
We’ve heard from you that performance is something you care about, and that it’s not always clear how to create performant Compose applications. We’re continuously improving the performance of Compose. For example, as of last October, we started migrating modifiers to a new and more efficient system, and we’re starting to see the results of that migration. For text alone, this work resulted in an average 22% performance gain that can be seen in the latest alpha release, and these improvements apply across the board. To get these benefits in your app, all you have to do is update your Compose version!
Text and TextField got many upgrades in the past months. Next to the performance improvements we already mentioned, Compose now supports the latest emoji version 🫶 and includes new text features such as outlining text, hyphenation support, and configuring line breaking behavior. Read more in the release notes of the compose-foundation and compose-ui libraries.
The new pager component allows you to horizontally or vertically flip through content, which is similar to ViewPager2 in Views. It allows deep customization options, making it possible to create visually stunning effects:
Choose a song using the HorizontalPager composable. Learn how to implement this and other fancy effects in Rebecca Franks' blog post.
The new flow layouts FlowRow and FlowColumn make it easy to arrange content in a vertical or horizontal flow, much like lines of text in a paragraph. They also enable dynamic sizing using weights to distribute the items across the container.
Using flow layouts to show the search filters in a real estate app
To learn more about the new features, performance improvements, and bug fixes, see the release notes of the latest stable and newest alpha release of the Compose libraries.
Tools
Developing your app using Jetpack Compose is much easier with the new and improved tools around it. We added tons of new features to Android Studio to improve your workflow and efficiency. Here are some highlights:
Compose Preview now supports live updates across multiple files, for example, if you make a change in your Theme.kt file, you can see all Previews updates automatically in your UI files.
Improving auto-complete behavior. For example, we now show icon previews when you’re adding Material icons, and we keep the @Composable annotation when running “Implement Members".
Showing Compose state information in the debugger. While debugging your app, the debugger will tell you exactly which parameters have “Changed” or have remained “Unchanged”, so you can more efficiently investigate the cause of the recomposition.
You can try out the new Studio Bot, an experimental AI powered conversational experience in Android Studio to help you generate code, fix issues, and learn about best practices, including all things Compose. This is an early experiment, but we would love for you to give it a try!
Emulator support for the newly announced Pixel Fold and Tablet Virtual Devices, so that you can test your Compose app before these devices launch later this year.
A new Espresso Device API that lets you apply rotation changes, folds, and other synchronous configuration changes to your virtual devices under test.
We’re also actively working on visual linting and accessibility checks for previews so you can automatically audit your Compose UI and check for issues across different screen sizes, and on multipreview templates to help you quickly add common sets of previews.
Material 3
Material 3 is the recommended design system for Android apps, and the latest 1.1 stable release adds a lot of great new features. We added new components like bottom sheets, date and time pickers, search bars, tooltips, and others. We also graduated many of the core components to stable, added more motion and interaction support, and included edge-to-edge support in many components. Watch this video to learn how to implement Material You in your app:
Extending Compose to more surfaces
We want Compose to be the programming model for UI wherever you run Android. This means including first-class support for large screens such as foldables and tablets and publishing libraries that make it possible to use Compose to write your homescreen widgets, smartwatch apps, and TV applications.
Large screen support
We’ve continued our efforts to make development for large screens easy when you use Compose. The pager and flow layouts that we released are common patterns on large screen devices. In addition, we added a new Compose library that lets you observe the device’s window size class so you can easily build adaptive UI.
When attaching a mouse to an Android device, Compose now correctly changes the mouse cursor to a caret when you hover the cursor over text fields or selectable text. This helps the user to understand what elements on screen they can interact with.
Glance
Today we publish the first beta version of the Jetpack Glance library! Glance lets you develop widgets optimized for Android phone, tablet, and foldable homescreens using Jetpack Compose. The library gives you the latest Android widget improvements out of the box, using Kotlin and Compose:
Glance simplifies the implementation of interactive widgets, so you can showcase your app’s top features, right on a user’s home screen.
Glance makes it easy to build responsive widgets that look great across form factors.
Glance enables faster UI Iteration with your designers, ensuring a high quality user experience.
Wear OS
We launched Compose for Wear OS 1.1 stable last December, and we’re working hard on the new 1.2 release which is currently in alpha. Here’s some of the highlights of the continuous improvements and new features that we are bringing to your wrist:
The placeholder and placeholderShimmer add elegant loading animations that can be used on chips and cards while content is loading.
expandableItems make it possible to fold long lists or long text, and only expand to show their full length upon user interaction.
Rotary input enhancements available in Horologist add intuitive snap and fling behaviors when a user is navigating lists with rotary input.
Android Studio now lets you preview multiple watch screen and text sizes while building a Compose app. Use the Annotations that we have added here.
Compose for TV
You can now build pixel perfect living room experiences with the alpha release of Compose for TV! With the new AndroidX TV library, you can apply all of the benefits of Compose to the unique requirements for Android TV. We worked closely with the community to build an intuitive API with powerful capabilities. Engineers from Soundcloud shared with us that “thanks to Compose for TV, we are able to reuse components and move much faster than the old Leanback View APIs would have ever allowed us to.” And Plex shared that “TV focus and scrolling support on Compose has greatly improved our developer productivity and app performance.”
Compose for TV comes with a variety of components such as ImmersiveList and Carousel that are specifically optimized for the living room experience. With just a few lines of code, you can create great TV UIs.
It’s great to see more and more internally and externally developed libraries add support for Compose. For example, loading pictures asynchronously can now be done with the GlideImage composable from the Glide library. And Google Maps released a library which makes it much easier to declaratively create your map implementations.
GoogleMap(
//...
) {
Marker(
state = MarkerState(position = LatLng(-34, 151)),
title = "Marker in Sydney"
)
Marker(
state = MarkerState(position = LatLng(35.66, 139.6)),
title = "Marker in Tokyo"
)
}
New and updated guidance
No matter where you are in your learning journey, we’ve got you covered! We added and revamped a lot of the guidance on Compose:
Learn hands-on with the Compose for Android Developers course, where you can learn the basics and deep dive into layouts, state, form factors, and more. We updated the course to include all the latest resources.
If you prefer watching videos, following on the well-received Compose Basics MAD Skills series, we recently published a new MAD Skills series on Layouts and Modifiers. With five episodes covering everything from the fundamentals to advanced concepts and functionality, a Q&A with Googlers, and a community tip, this series will help you to quickly improve your Compose Layout knowledge.
Learn how to implement Material 3 theming in your app with the new codelab.
Happy Composing!
We hope you're as excited by these developments as we are! If you haven't started yet, it's time to learn Jetpack Compose and see how your team and development process can benefit from it. Get ready for improved velocity and productivity. Happy Composing!

We first announced Android Studio at I/O 2013 with a promise to deliver a best-in-class integrated development environment (IDE) focused on Android app developers. 10 years later, this commitment to developer productivity still drives the team to deliver new tools and solutions that help teams around the world to create amazing app experiences for their users. And with Google's push to unlock the power of AI to help you throughout your day, Android Studio Hedgehog introduces a key breakthrough: an AI-powered conversational experience designed to make you more productive.
In addition to accelerating coding productivity, this latest version of the IDE provides better tools when you develop for multiple form factors, and helps you improve app quality with new insights, debugging, and testing solutions. All these improvements add to the many updates we’ve included in Android Studio Giraffe, which is now in the Beta channel and helps make it easier to configure your builds with Kotlin DSL support, improve sync times with new data and guidance, target the latest Android SDK version with the new Android SDK Upgrade Assistant, and more.
To see highlights of the new features in action including Studio Bot, watch the What’s new in Android Developer Tools session from Google I/O 2023.
What’s new in Android Development Tools - with Studio Bot Demo
At the heart of our mission is to accelerate your ability to write high-quality code for Android. In this release we are excited to introduce an AI-powered conversational experience called Studio Bot, that leverages Codey, Google's foundation model for coding that is a descendant of PaLM 2, to help you generate code for your app and make you more productive. You can also ask questions to learn more about Android development or help fix errors in your existing code — all without ever having to leave Android Studio. Studio Bot is in its very early days, and we’re training it to become even better at answering your questions and helping you learn best practices. We encourage you to try it out for yourselves, and help it improve by sharing your feedback directly with Studio Bot.
Privacy is top of mind, and what is unique in this integration is that you don’t need to send your source code to Google to use Studio Bot—only the chat dialogue between you and Studio Bot is shared. Much like our work on other AI projects, we stick to a set of principles that hold us accountable. We’re taking a measured approach to our rollout; for this initial launch, Studio Bot is only available to Android developers in the US. You can read more here
Studio Bot
Live Edit
Live Edit helps keep you in the flow by minimizing interruptions when you make updates to your Compose UI and validates those changes on a running device. You can use it in manual mode to control when the running app should be updated or in automatic mode to update the running app as you make code changes. Live Edit is available in Android Studio Giraffe Beta, with the Hedgehog release providing additional improvements in error handling and reporting.
Live Edit with Compose
Build productivity
Kotlin DSL and Version Catalogs
A number of updates help you leverage more modern syntax and conventions when configuring your build. Kotlin is the recommended language when developing for Android. Now, with official support for Kotlin DSL in your Gradle build scripts, it’s also the preferred way to configure your build because Kotlin is more readable and offers better compile-time checking and IDE support. Additionally, we’ve also added experimental support for TOML-based Gradle Version Catalogs, a feature that lets you manage dependencies in one central location and share dependencies across modules or projects. Android Studio now makes it easier to configure version catalogs through editor suggestions and integrations with the Project Structure dialog, plus the New Project Wizard.

Typically, multilingual users set their system language to one language—such as English—but they want to select other languages for specific apps, such as Dutch, Chinese, or Hindi. Android 13 introduced support for per-app language preferences, and now Android Gradle plugin 8.1 and higher can configure your app to support it automatically. Learn more.
Download impact during Sync
When using Android Gradle Plugin 7.3 or higher, The Build > Sync tool window now includes a summary of time spent downloading dependencies and a detailed view of downloads per repository, so you can easily determine whether unexpected downloads are impacting build performance. Additionally, it can help you identify inefficiencies in how you configure your repositories. Learn more.

New Android SDK Upgrade Assistant
Android Studio Giraffe introduces the Android SDK Upgrade Assistant, a new tool that helps you upgrade the targetSdkVersion, which is the API level that your app targets. Instead of having to navigate every API change with an Android SDK release, the Android SDK Upgrade Assistant guides you through upgrading targetSdkVersion level by level by creating a customized filter of API changes that are relevant to your app. For each migration step, it highlights the major breaking changes and how to address them, helping you get to taking advantage of what the latest versions of Android have to offer much more quickly. To open the Android SDK Upgrade Assistant, go to Tools > Android SDK Upgrade Assistant. In the Assistant panel, select the API level that you want to upgrade to for guidance.

Emulator Support for Wear OS 4 Developer Preview
Wear OS 4 is the next generation OS for Wear. Based on Android 13, it officially launches in the fall and has a great selection of new features and optimizations. We’re giving you a preview of all the new platform features with the new Wear OS 4 emulator. We recommend you try it with Android Studio Hedgehog and test that your Wear OS app works as intended with the latest platform updates. The Wear OS 4 emulator will give you a faster and smoother transition to Wear OS 4, and help you make apps ready in time for the official Wear OS 4 release on real devices. Check out the Wear 4 Preview site for how to get started with the new Wear OS 4 emulator.
Watch Face Format support in Wear OS 4 Emulator
Together with Samsung, we’re excited to announce the launch of the Watch Face Format, a new way to build watch faces for Wear OS. The Watch Face Format is a declarative XML format, meaning there will be no code in your watch face APK. The platform takes care of the logic needed to render the watch face so you no longer have to worry about code optimizations or battery performance. Use watch face creation tools such as Watch Face Studio to design watch faces, or you can manually or dynamically edit the watch face format to build watch faces directly. You can test the new Watch Face Format on the Wear OS 4 emulator.

Device Mirroring for local devices
Whether you use a direct USB connection or ADB over Wi-Fi, Device Mirroring lets you see and interact with your local physical devices directly within the Android Studio Running Devices window. This feature lets you focus on how you develop and test your app all in one place. With the Hedgehog release, we’re adding more functionality, including the ability to mirror Wear OS devices and simulate folding actions on foldable devices directly from the IDE.

Android Device Streaming
We know sometimes it’s critical for you to see and test how your apps work on physical hardware to ensure that your users have the best experience. However, accessing the latest flagship devices isn’t always easy. Building on top of Device Mirroring for local devices, we’re introducing device streaming of remote physical Google Pixel devices, such as the Pixel Fold and Pixel Tablet, directly within Android Studio. Device streaming will let you deploy your app to these remote devices and interact with them, all without having to leave the IDE. If you’re interested in getting early access later this year, enroll now.
Espresso Device API
Automated testing of your app using Espresso APIs helps you catch potential issues early, before they reach users. However, testing your app across configuration changes, such as rotating or folding a device, has always been a challenge. Espresso Device API is now available to help you write tests that perform synchronous configuration changes when testing on Android virtual devices running API level 24 and higher. You can also set up test filters to ensure that tests that require certain device features, such as a folding action, only run on devices that support them. Learn more.

Improve your app quality
App Quality Insights with Android vitals
App Quality Insights launched in Android Studio Electric Eel to provide access to Firebase Crashlytics issue reports directly from the IDE. The integration lets you navigate between your stack trace and code with a click, use filters to see only the most important issues, and see report details to help you reproduce issues. In Android Studio Hedgehog, you can now view important crash reports from Android vitals, powered by Google Play. Android vitals reports also include useful insights, such as notes from SDK providers so that you can quickly diagnose and resolve crashes related to SDKs your app might be using.

App Quality Insights with improved code navigation
When you publish your app using the latest version of AGP 8.2, crash reports now attach minimal git commit hash data to help Android Studio navigate to your code when investigating Crashlytics crash reports in the IDE. Now, when you view a report that includes the necessary metadata, you can choose to either navigate to the line of code in your current git checkout, or view a diff between the checkout and the version of your codebase that generated the crash. To get started with the right dependencies, see the documentation.
Compose State information in Debugger
When parts of your Compose UI recompose unexpectedly, it can sometimes be difficult to understand why. Now, when setting a breakpoint on a Composable function, the debugger lists the parameters of the composable and their state, so you can more easily identify what changes might have caused the recomposition. For example, when you pause on a composable, the debugger can tell you exactly which parameters have “Changed” or have remained “Unchanged”, so you can more efficiently investigate the cause of the recomposition.
Compose state information in the debugger
New Power Profiler
We are excited to announce a brand new Power Profiler in Android Studio Hedgehog, which shows power consumption on the Pixel 6 and higher devices running Android 10 and higher. Data is segmented by each sub-system (such as, Camera, GPS, and more). This data is made available when recording a System Trace via the Profiler and helps you to visually correlate power consumption of the device to the actions happening in your app. For example, you can A/B test multiple algorithms of your video calling app to optimize power consumed by the camera sensor.
The new Power Profiler
Device Explorer
The Device File Explorer in Giraffe has been renamed to Device Explorer and updated to include information about debuggable processes running on connected devices. In addition to the Files tab, which includes existing functionality that allows you to explore a device’s file hierarchy, the new Processes tab allows you to view a list of debuggable processes for the connected device. From there you can also select a process and perform a Kill process action (which runs am kill), a Force stop (which runs am force-stop) , or attach the debugger to a selected process.

Compose animation preview
Compose Animation Preview in Android Studio Hedgehog now supports a number of additional Compose APIs, animate*AsState, CrossFade, rememberInfiniteTransition, and AnimatedContent (in addition to updateTransition and AnimatedVisibility). Compose Animation Preview also has new pickers that let you set non-enum or boolean states to debug your Compose animation using precise inputs. For all supported Compose Animation APIs, you can play, pause, scrub, control speed, and coordinate.

Embedded Layout Inspector
You can now run Layout Inspector directly embedded in the Running Device Window in Android Studio! Try out this feature today in Android Studio Hedgehog to conserve screen real estate and organize your UI debugging workflow in a single tool window. You can access common Layout Inspector features such as debugging the layout of your app by showing a view hierarchy and allowing you to inspect the properties of each view. Additionally, because the embedded Layout Inspector overlays on top of the existing device mirroring stream, overall performance when using the inspector is now much faster. To get started and understand known limitations, read the release notes.

Firebase Test Lab support for Gradle Managed Devices
Gradle Managed Devices launched in Android Gradle Plugin (AGP) 7.3 to make it easier to utilize virtual devices when running automated tests in your continuous integration (CI) infrastructure by allowing Gradle to manage all aspects of device provisioning. All you need to do is use the AGP DSL to describe the devices you wanted Gradle to use. But sometimes you need to run your tests on physical Android devices. With AGP 8.2, we have expanded Gradle Managed Devices with the ability to target real physical (and virtual) devices running in Firebase Test Lab (FTL). The capability makes it easier than ever to scalably test across the large selection of FTL devices with only a few simple steps. Additionally, this version of AGP can also take advantage of FTL’s new Smart Sharding capabilities, which allows you to get test results back much more quickly by utilizing multiple devices that run in parallel. To learn more and get started, read the release notes.

IntelliJ
IntelliJ Platform Update
Android Studio Hedgehog (2023.1) includes the IntelliJ 2023.1 platform release, which comes with IDE startup performance improvements, faster import of Maven projects, and a more streamlined commit process. Read the IntelliJ release notes here.
New UI
Along with the IntelliJ platform update comes further improvements to the New UI. In large part due to community feedback, there’s a new Compact Mode, which provides a more consolidated look and feel of the IDE, and an option to vertically split the tool window area and conveniently arrange the windows, just like in the old UI. We also improved the Android-specific UI by updating the main toolbar, tool windows, and new iconography. To use the New UI, enable it in Settings > Appearance & Behavior > New UI. For a full list of changes, see the IntelliJ New UI documentation.
