Today we're releasing the first Beta of Android 14, building around 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. We've been making steady progress refining the features and stability of Android 14, and it's time to open the experience up to both developers and early-adopters.

Android delivers enhancements and new features year-round, and your feedback on the Android beta program plays a key role in helping Android continuously improve. The Android 14 developer site has lots more information about the beta, including downloads for Pixel and the release timeline. We’re looking forward to hearing what you think, and thank you in advance for your continued help in making Android a platform that works for everyone.


Working across form factors

Android 14 builds on the work done in past releases to support tablets and foldable form factors, and we've been building tools and resources to help polish your app experience, including design inspiration and development guides.


Smarter System UI

In the Android operating system, features are implemented by two separate yet equally important packages: the framework, which provides services, and the System UI, which gives the user control of those services. Each Android release brings new refinements to the system UI, and here are some that you might notice in Beta 1.

The gesture navigation experience includes a more prominent back arrow while interacting with your app to help improve back gesture understanding and usefulness. The back arrow also compliments the user's wallpaper or device theme.



A superior system sharesheet

In Android 14, apps can now add custom actions to system sharesheets they invoke. Create your custom ChooserAction using ChooserAction.Builder and specify a list of your ChooserActions as the Intent.EXTRA_CHOOSER_CUSTOM_ACTIONS of the Intent created with Intent.createChooser.

In addition, the system now uses more app signals to determine the ranking of the direct share targets. You provide the signal by calling pushDynamicShortcut to report shortcut usage with the corresponding capability bindings.






More graphics capabilities

Android 14 adds new graphics features that you can use to make your app really stand out.


Paths are now queryable and interpolatable

Android's Path API is a powerful and flexible mechanism for creating and rendering vector graphics. Starting in Android 14, you can query paths to find out what's inside of them. The API updates include functionality to interpolate between paths whose structures match exactly, enabling morphing effects, and an AndroidX library provides backwards compatibility back to API 21. More details here.


Personalization

 Per-app language preferences

Android 14 enhances per-app language preferences, allowing for dynamic customization of the set of languages displayed in the Android Settings per-app language list, and giving IMEs a way to know the UI language of the current app. Starting with Android Studio Giraffe Canary 7 and AGP 8.1.0-alpha07, you can configure your app to support per-app language preferences automatically. Based on your project resources, the Android Gradle plugin generates the LocaleConfig file and adds a reference to it in the generated manifest file, so you no longer have to create or update the file manually when your language support changes. See Automatic per-app language support for more information and leave feedback.


Privacy

 Limiting visibility to disability-focused accessibility services

Android 14 introduces the accessibilityDataSensitive attribute to allow apps to limit visibility of specified views only to accessibility services that claim to help users with disabilities. Play Protect ensures apps downloaded from the Play Store are truthful about these claims. TalkBack and other services that claim to help users with disabilities will not be affected by this attribute.

Apps can consider using accessibilityDataSensitive to:

  • Protect user data (such as personal details or plaintext passwords) 
  • Prevent critical actions from being executed unintentionally (such as transfering money or checking out in a shopping app)
    •  

App compatibility

If you haven't yet tested your app for compatibility with Android 14, now is the time to do it! With Android 14 now in beta, we're opening up access to early-adopter users as well as developers. In the weeks ahead, you can expect more users to be trying your app on Android 14 and raising issues they find.

To test for compatibility, install your published app on a device or emulator running Android 14 Beta and work through all of the app’s flows. Review the behavior changes to focus your testing. After you’ve resolved any issues, publish an update as soon as possible.

It’s also a good time to start getting ready for your app to target Android 14, by testing with the app compatibility changes toggles in Developer Options.

Get started with Android 14

Today's Beta 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, the easiest way to get started is using the Android Emulator in a tablet or foldable configuration in the latest preview of the Android Studio SDK Manager. Now that we've entered the beta phase, you can enroll any supported Pixel device here to get this and future Android 14 Beta and feature drop Beta updates over-the-air. If you don’t have a Pixel device, you can use the 64-bit system images with the Android Emulator in Android Studio.

For the best development experience with Android 14, we recommend that you use the latest preview of Android Studio Giraffe (or more recent Giraffe+ versions). Once you’re set up, here are some of the things you should do:

  • Try the new features and APIs - your feedback is critical as we finalize the 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 preview and beta system images and SDK regularly throughout the Android 14 release cycle.

If you are already enrolled in the Android 13 QPR Beta program and your device is supported, Android 14 Beta 1 will be made available to you without taking any additional action.

Reduce uninstalls for your app with auto-archive

Posted by Chang Liu and Lidia Gaymond, Product Managers, Google Play

Did you know that one of the main reasons users uninstall apps is to free up space? Today, whenever users try to install a new app on a nearly-full device, they see a dialog that allows them to manually uninstall the app to make room. However, sometimes uninstalling a whole app, including all of the user’s app data just isn’t necessary.

To reduce unnecessary uninstalls and help users successfully install new apps, we are introducing a new feature: auto-archive. Once a user opts in, auto-archive can help them automatically free up to nearly 60% of an app’s storage space, without removing the app presence or users’ data from the device.

What is auto-archive?
image of a phone screen illustrating the archiving experience
Archived apps are visually indicated with cloud icons and remain on the user's device.

Auto-archive is a new feature that allows users to free up space on their device without the need to completely uninstall an app. Once the user opts in, infrequently used apps will be partly removed from the device to save space, whilst the app icon and the user’s personal app data will be preserved. When the user wants to start using the app again, they can simply tap to re-download it and pick up where they left off (as long as the app is still available on Google Play).


Eligibility of auto-archive

Auto-archive is only available for developers using the App Bundle to publish their apps. If your app supports archiving, users will be less likely to see it surfaced amongst uninstall suggestions.

How it works

Users can opt into auto-archive in a few steps.

  1. The user tries to install a new app when the device is out of storage.
  2. A pop-up window appears asking if the user wants to enable auto-archive.
  3. If the user opts in, unused apps on the user's device will be auto-archived to free up enough space for a new app request.

Auto-archive is an easy way for users to manage their device storage, and a great way for developers to lower the likelihood of their apps being uninstalled.


Giving Users More Transparency and Control Over Account Data

Posted by Bethel Otuteye, Senior Director, Product Management, Android App Safety

Google Play has launched a number of recent initiatives to help developers build consumer trust by showcasing their apps' privacy and security practices in a way that is simple and easy to understand. Today, we’re building on this work with a new data deletion policy that aims to empower users with greater clarity and control over their in-app data.

For apps that enable app account creation, developers will soon need to provide an option to initiate account and data deletion from within the app and online. This web requirement, which you will link in your Data safety form, is especially important so that a user can request account and data deletion without having to reinstall an app.

While Play’s Data safety section already lets developers highlight their data deletion options, we know that users want an easier and more consistent way to request them. By creating a more intuitive experience with this policy, we hope to better educate our shared users on the data controls available to them and create greater trust in your apps and in Google Play more broadly.

As the new policy states, when you fulfill a request to delete an account, you must also delete the data associated with that account. The feature also gives developers a way to provide more choice: users who may not want to delete their account entirely can choose to delete other data only where applicable (such as activity history, images, or videos). For developers that need to retain certain data for legitimate reasons such as security, fraud prevention, or regulatory compliance, you must clearly disclose those data retention practices.

Note: Images are examples and subject to change

While we’re excited about the greater control this will give people over their data, we understand it will take time for developers to prepare, especially those without an existing deletion functionality or web presence, which is why we’re sharing information and resources today.

As a first step, we’re asking developers to submit answers to new Data deletion questions in your app’s Data Safety form by December 7. Early next year, Google Play users will begin to see reflected changes in your app’s store listing, including the refreshed data deletion badge in the Data safety section and the new Data deletion area.

Developers who need more time can file for an extension in Play Console until May 31, 2024 to comply with the new policy.

For more information on data deletion and other policy changes announced today:

As always, thank you for your continued partnership in making Google Play a safe and trustworthy platform for everyone.

Mercari reduces 355K lines of code, a 69% difference, by rebuilding with Jetpack Compose

Posted by the Android team

In 2020, the Mercari team took on a big initiative to update its app’s technical infrastructure. At the time, its codebase was seven years old and hadn’t undergone any major architectural updates. This affected the team’s ability to develop new features and release timely app updates. To resolve this technical debt, Mercari launched what it called the GroundUP initiative—a complete rewrite of its application across platforms, including Android.

The goal was to create a completely modernized application with a scalable design. While retooling the app, Mercari developers turned to Jetpack Compose, Android’s modern declarative toolkit for creating native UI. During the evaluation, the team learned rewriting in Jetpack Compose would help clean up their codebase and have more control over how the app looks.

A rewrite with less code

The Mercari team completely rewrote the architecture and tech stack for its Android app using Jetpack Compose. Mercari developers created a new design system and completely integrated it using Compose, enabling them to easily test and implement new features. Using this new design system, the Mercari team rewrote more than 130 UI screens for its marketplace and modernized the look and feel of many of their components.

With the help of the Jetpack Libraries, Mercari’s team eliminated all legacy code during the rewrite, drastically reducing its codebase and making it more manageable for developers. “Virtually, it’s the same app with way less code,” said Allan Conda, Android technology lead at Mercari. “The rewritten app has about 355,000 fewer lines of code, which is about 69% less than what it had before.”

Interoperability with Views as an early adopter

When the Mercari team first began its GroundUP initiative, Jetpack Compose was only available in developer preview. They wanted the app written completely in Jetpack Compose due to its new declarative approach to creating UI. However, because it was still so new, they found themselves having to solve for unique edge cases using both toolkits.

For example, on Mercari’s listing form screens, users are prompted to input details about the merchandise they want to list. Users were then supposed to be able to select photos from their device gallery and rearrange them on this screen using a drag gesture. Gesture APIs weren’t available in Jetpack Compose at the time, so the team took advantage of Compose's AndroidView to seamlessly integrate Views that handled gestures on the listing form screen. This provided a stable yet temporary solution to implementing drag gestures until the feature became available with Jetpack Compose.

The Mercari team was impressed by how easy it was to switch between the two toolkits, and having the option to use Views alongside Compose gave them better control of edge cases like this. Compose now supports gesture APIs, and Mercari developers have since completely written and integrated the drag gesture component solely using Compose.

Jetpack Compose has matured a lot since Mercari’s initial adoption, and most Android developers no longer need to worry about having to interoperate with both toolkits as Android apps can now be written completely in Compose.

Improving and monitoring performance with Compose

Using Compose, the Mercari team automated baseline profile generation for every stable release of the app and found it to be really helpful. The home screen renders frames up to 2x faster with the default Compose baseline profile compared to without a baseline profile. By providing a custom profile, there’s an additional improvement of up to 20% faster when Mercari users are scrolling compared to just having the default baseline profile.

The team also wrote automated performance tests based on the app’s core scenarios with Android Macrobenchmark. “Using Android Macrobenchmark, we can automatically test start-up, scroll, and screen load times performance,” said Allan. “Currently, we have six core scenarios covered by these tests, like search results and browsing items.”

Additionally, Mercari developers integrated Firebase Performance Monitoring, a real-time app performance monitoring tool, with custom code to calculate scrolling performance on Compose screens. With Firebase Performance Monitoring, the Mercari team detected a performance issue on its search result screen. Using the Android Profiler to pinpoint the problem, Mercari developers discovered there were poor frame rates when scrolling search results. This resulted in the slow rendering instances being reduced by around 23.6%.

The Mercari team solved this frame rate issue with guidance from Google’s Compose performance best practices and Compose stability. Mercari developers had the app skip its Composables and hoist the unused states on the search results screen, significantly improving the frame rates.

More opportunities with Jetpack Compose

With less code to maintain, it’s much easier for Mercari developers to test and implement features. “We have a ton of experiments we can finally conduct using our refreshed platforms. Our users can expect new features coming to the Mercari app at a faster rate,” said Allan.

Mercari’s developers are excited to further develop the app using Animation APIs. With Compose, it’s much easier to animate components, which can result in huge improvements for Android UXs.

Concepts users spend 70% more time using the app on tablets than on phones

Posted by the Android team

Concepts is a digital illustration app created by TopHatch that helps creative thinkers bring their visions to life. The app uses an infinitely-large canvas format, so its users can sketch, plan, and edit all of their big ideas without limitation, while its vector-based ink provides the precision needed to refine and reorganize their ideas as they go.

For Concepts, having more on-screen real estate means more comfort, more creative space, and a better user experience overall. That’s why the app was specifically designed with large screens in mind. Concepts’ designers and engineers are always exploring new ways to expand the app’s large screen capabilities on Android. Thanks to Android’s suite of developer tools and resources, that’s easier than ever.

Evaluating an expanding market of devices

Large screens are the fastest growing segment of Android users, with more than 270 million users on tablets, foldables, and ChromeOS devices. It’s no surprise then that Concepts, an app that benefits users by providing them with more screen space, was attracted to the format. The Concepts team was also excited about innovation with foldables because having the large screen experience with greater portability gives users more opportunities to use the app in the ways that are best for them.

The team at Concepts spends a lot of time evaluating new large screen technologies and experiences, trying to find what hardware or software features might benefit the app the most. The team imagines and storyboards several scenarios, shares the best ones with a close-knit beta group, and quickly builds prototypes to determine whether these updates improve the UX for its larger user base.

For instance, Concepts’ designers recently tested the Samsung Galaxy Fold and found that users benefited from having more screen space when the device was folded. With help from the Jetpack WindowManager library, Concepts’ developers implemented a feature to automatically collapse the UI when the Galaxy’s large screen was folded, allowing for more on-screen space than if the UI were expanded.

Foldable UI

Concepts’ first release for Android was optimized for ChromeOS and, because of this, supporting resizable windows was important to their user experience from the very beginning. Initially, they needed to use a physical device to test for various screen sizes. Now, the Concepts team can use Android’s resizeable emulator, which makes testing for different screen sizes much easier.

Android’s APIs and toolkit carry the workload

The developers’ goal with Concepts is to make the illustration experience feel as natural as putting pen to paper. For the Concepts team, this meant achieving as close to zero lag as possible between the stylus tip and the lines drawn on the Concepts canvas.

When Concepts’ engineers first created the app, they put a lot of effort into creating low-latency drawing themselves. Now, Android’s graphical APIs eliminate the complexity of creating efficient inking.

“The hardware to support low-latency inking with higher refresh rate screens and more accurate stylus data keeps getting better,” said David Brittain, co-founder and CEO of TopHatch, parent company of Concepts. “Android’s mature set of APIs make it easy.”

Concepts engineers also found that the core Android View APIs take care of most of the workload for supporting tablets and foldables and make heavy use of custom Views and ViewGroups in Concepts. The app’s color wheel, for example, is a custom View drawing to a Canvas, which uses Animators for the reveal animation. View, Canvas, and Animator are all classes from the Android SDK.

“Android’s tools and platform are making it easier to address the variety of screen sizes and input methods, with well-structured APIs for developing and increasing the number of choices for testing. Plus, Kotlin allows us to create concise, readable code,” said David.


Concepts’ users prefer large screens

Tablets and foldables represent the bulk of Concepts’ investments and user base, and the company doesn’t see that changing any time soon. Currently, tablets deliver 50% higher revenue per user than smartphone users. Tablets also account for eight of the top 10 most frequently used devices among Concepts’ users, with the other two being ChromeOS devices.

Additionally, Concepts’ monthly users spend 70% more time engaging with the app on tablets than on traditional smartphones. The application’s rating is also 0.3 stars higher on tablets.

“We’re looking forward to future improvements in platform usability and customization while increasing experimentation with portable form factors. Continued efforts in this area will ensure high user adoption well into the future,” said David.

Play Commerce prevented over $2 billion in fraudulent and abusive transactions in 2022

Posted by Sheenam Mittal, Product Manager, Google Play

Google Play Commerce enables you to monetize your apps and games at scale in over 170 markets, without the complexities and time consumption required to run your own global commerce platform. It enables you to easily transact with millions of users around the world and gives users trusted and safe ways to pay for your digital products and content. Ensuring developers and users have a secure purchase experience has been a key pillar of Play Commerce, and we achieve this by continuously preventing and monitoring for bad actors looking to defraud and abuse your apps.

Preventing fraud and securing purchases

In 2022, we prevented over $2 billion in fraudulent and abusive transactions. Bad actors looking to carry out abuse on apps implement an array of strategies across both one–time purchases as well as auto-renewing payments. For example, they may attempt to purchase an item in your app with a compromised form of payment, or request a refund for an in-app purchase that’s been already consumed or sold, or use scammed gift cards for purchases. When a combined or coordinated attempt is carried out by bad actors, it can result in large-scale abuse on your app. Preventing such fraud and abuse requires a comprehensive approach, consisting of automated solutions and an array of internal monitoring tools combined with human expertise.

Empower developers with tools to mitigate app abuse

Information asymmetry between Google Play and developers is commonly exploited by bad actors. Two of the most effective solutions that you can implement to help address this are Voided Purchases API and Obfuscated Account ID. Over 70% of our top 200 monetizing developers have integrated these solutions to reduce fraud and abuse on their apps.

  • Voided Purchases API provides you with a list of in-app and subscription orders for each user that have been voided. You can implement revocation that prevents the user from accessing products from those orders.
Diagram detailing Improve losses, preserve app economy, and secure game integrity as benfits of Voided Purchases API
Benefits of Voided Purchases API
  • Obfuscated Account ID helps Play detect fraudulent transactions, such as many devices making purchases on the same account in a short period of time.

You can also use Play Integrity API to protect your apps and games from potentially risky and fraudulent interactions, such as cheating and unauthorized access. You call the Play Integrity API at important moments to check that user actions or server requests are coming from your unmodified app, installed by Google Play, running on a genuine Android device. If something is wrong, your app’s backend server can respond with appropriate actions to prevent attacks and reduce abuse. Developers using the API have seen an average of over 50% reduction in unauthorized access of their apps and games. Stay tuned for new highly-requested feature updates.

Flowchart of how Play Integrity API works

Looking forward

This month, we launched Purchases.product.consume, which allows you to consume in-app items using the Play Developer API, reducing the risk of client-side abuse by shifting more business logic to your secure backends. For example, if a bad actor purchases an item from your app but tampers with the client side, the purchase will be automatically refunded due to lack of acknowledgement after 3 days of purchase. Using server side consumption will prevent this type of app abuse.

Google Play Commerce is committed to providing developers and users a secure purchase experience. Learn more about how to prevent bad actors from harming users and abusing your app by visiting this guide, as well as other 2023 initiatives helping keep Android and Google Play safe.

What’s new in the Jetpack Compose March ’23 release

Posted by Jolanda Verhoef, Android Developer Relations Engineer

Today, as part of the Compose March ‘23 Bill of Materials, we’re releasing version 1.4 of Jetpack Compose, Android's modern, native UI toolkit that is used by apps such as Booking.com, Pinterest, and Airbnb. This release contains new features like Pager and Flow Layouts, and new ways to style your text, such as hyphenation and line-break behavior. It also improves the performance of modifiers and fixes a number of bugs.

Swipe through content with the new Pager composable

Compose now includes out-of-the-box support for vertical and horizontal paging between different content. Using VerticalPager or HorizontalPager enables similar functionality to the ViewPager in the view system. However, just like the benefits of using LazyRow and LazyColumn, you no longer need to create an adapter or fragments! You can simply embed a composable inside the Pager:

// Display 10 items HorizontalPager(pageCount = 10) { page -> // Your specific page content, as a composable: Text( text = "Page: $page", modifier = Modifier.fillMaxWidth() ) }

ALT TEXT

These composables replace the implementation in the Accompanist library. If you already use the Accompanist implementation, check out the migration guide. See the Pager documentation for more information.

Get your content flowing with the new Flow Layouts

FlowRow and FlowColumn provide an efficient and compact way to lay out items in a container when the size of the items or the container are unknown or dynamic. These containers allow the items to flow to the next row in the FlowRow or next column in the FlowColumn when they run out of space. These flow layouts also allow for dynamic sizing using weights to distribute the items across the container.

Here’s an example that implements a list of filters for a real estate app:

ALT TEXT

@Composable fun Filters() { val filters = listOf( "Washer/Dryer", "Ramp access", "Garden", "Cats OK", "Dogs OK", "Smoke-free" ) FlowRow( horizontalArrangement = Arrangement.spacedBy(8.dp) ) { filters.forEach { title -> var selected by remember { mutableStateOf(false) } val leadingIcon: @Composable () -> Unit = { Icon(Icons.Default.Check, null) } FilterChip( selected, onClick = { selected = !selected }, label = { Text(title) }, leadingIcon = if (selected) leadingIcon else null ) } } }

Performance improvements in Modifiers

The major internal Modifier refactor we started in the October release has continued, with the migration of multiple foundational modifiers to the new Modifier.Node architecture. This includes graphicsLayer, lower level focus modifiers, padding, offset, and more. This refactoring should bring performance improvements to these APIs, and you don't have to change your code to receive these benefits. Work on this continues, and we expect even more gains in future releases as we migrate Modifiers outside of the ui module. Learn more about the rationale behind the changes in the ADS talk Compose Modifiers deep dive.

Increased flexibility of Text and TextField

Along with various performance improvements, API stabilizations, and bug fixes, the compose-text 1.4 release brings support for the latest emoji version, including backwards compatibility with older Android versions 🎉🙌. Supporting this requires no changes to your application. If you’re using a custom emoji solution, make sure to check out PlatformTextStyle(emojiSupportMatch).

In addition, we’ve addressed one of the main pain points of using TextField. In some scenarios, a text field inside a scrollable Column or LazyColumn would be obscured by the on-screen keyboard after being focused. We re-worked core parts of scroll and focus logic, and added key APIs like PinnableContainer to fix this bug.

Finally, we added a lot of new customization options to Text and its TextStyle:

  • Draw outlined text using TextStyle.drawStyle.
  • Improve text transition and legibility during animations using TextStyle.textMotion.
  • Configure line breaking behavior using TextStyle.lineBreak. Use built-in semantic configurations like Heading, Paragraph, or Simple, or construct your own LineBreak configuration with the desired Strategy, Strictness, and WordBreak values.
  • Add hyphenation support using TextStyle.hyphens.
  • Define a minimum number of visible lines using the minLines parameter of the Text and TextField composables.
  • Make your text move by applying the basicMarquee modifier. As a bonus, because this is a Modifier, you can apply it to any arbitrary composable to make it move in a similar marquee-like fashion!
    • ALT TEXT
    Marquee text using outline with shapes stamped on it using the drawStyle API.

Improvements and fixes for core features

In response to developer feedback, we have shipped some particularly in-demand features & bug fixes in our core libraries:
  • Test waitUntil now accepts a matcher! You can use this API to easily synchronize your test with your UI, with specific conditions that you define.
  • animatedContent now correctly supports getting interrupted and returning to its previous state.
  • Accessibility services focus order has been improved: the sequence is now more logical in common situations, such as with top/bottom bars.
  • AndroidView is now reusable in LazyList if you provide an optional onReset lambda. This improvement lets you use complex non-Compose-based Views inside LazyLists.
  • Color.lerp performance has been improved and now does zero allocations: since this method is called at high frequency during fade animations, this should reduce the amount of garbage collection pauses, especially on older Android versions.
  • Many other minor APIs and bug fixes as part of a general cleanup. For more information, see the release notes.
