Create a virtual device (emulator)

First, Android 10 is shaping the leading edge of mobile innovation with advanced machine-learning and support for emerging devices like foldables and 5G enabled phones. Next, Android 10 has a central focus on privacy and security, with almost 50 features that give users greater protection, transparency, and control. Finally, Android 10 expands users' digital wellbeing controls so individuals and families can find a better balance with technology.

Many partner devices, including those in the Beta program, will receive the update by the end of the year. Your support and engagement are what make Android such an amazing platform. In fact, Android 10 will be available on more devices than any other previous release. Android is fortunate to have such a passionate community! To get started developing for Android 10, visit developer.

Make sure to check out our Keyword blog for more too! With Android 10 you can take advantage of the latest hardware and software innovations to build amazing app experiences for users. Foldables - Building on robust multi-window support, Android 10 extends multitasking across app windows and provides screen continuity to maintain your app state as the device folds or unfolds. For details on how to optimize your apps for foldables, see the developer guide. You can use connectivity APIs to detect if the device has a high bandwidth connection and check whether the connection is metered.

With these, your apps and games can tailor rich, immersive experiences to users over 5G. The ML speech models run right on the phone, and no audio stream ever leaves the device. For developers, Live Caption is optional , but expands the audience for your apps and games by making your content more accessible with a single tap. Smart Reply in notifications - Android 10 uses on-device ML to suggest contextual actions in notifications, such as smart replies for messages or opening a map for an address in the notification.

You can build a custom dark theme for your app or let the system create one dynamically from your current theme. See the developer guide for details. Gesture navigation - Android 10 introduces a fully gesture navigation mode that eliminates the navigation bar area and allows apps to use the full screen to deliver richer, more immersive experiences. Get started optimizing your app today. Privacy is a central focus in Android 10, from stronger protections in the platform to new features designed with privacy in mind. Building on previous releases, Android 10 includes extensive changes to protect privacy and give users control, with improved system UI, stricter permissions, and restrictions on what data apps can use.

See the Android 10 developer site for details on how to support these in your apps. Giving users more control over location data - Users have more control over their location data through a new permission option -- they can now allow an app to access location only while the app is actually in use running in the foreground. To learn more about location changes, see the developer guide or our blog post. Protecting location data in network scans - Most of the APIs for scanning networks already required the coarse location permission. Android 10 increases the protection around those APIs by requiring the fine location permission instead.

Preventing device tracking - Apps can no longer access non-resettable device identifiers that could be used for tracking, including device IMEI, serial number, and similar identifiers. Read the best practices to help you choose the right identifiers for your use case, and see the details here. Securing user data in external storage - Android 10 introduces a number of changes to give users more control over files in external storage and the app data within them.

Apps can store their own files in their private sandboxes, but must use MediaStore to access shared media files and use the system file picker to access shared files in the new Downloads collection. Learn more here. Blocking unwanted interruptions - Android 10 prevents app launches from the background that unexpectedly jump into the foreground and take over focus from another app. Read more about our long-term work on Security in Quantifying Measurable Security. But there is no finish line when it comes to Security. Storage encryption - All compatible devices launching with Android 10 are required to encrypt user data, and to make this more efficient, Android 10 includes Adiantum , our new encryption mode.

TLS 1. Platform hardening - Android 10 also includes hardening for several security-critical areas of the platform, and updates to the BiometricPrompt framework with robust support for face and fingerprint in both implicit and explicit authentication. Read more about Android 10 security updates here. Dynamic depth for photos - Apps can now request a Dynamic Depth image, which consists of a JPEG, XMP metadata related to depth related elements, and a depth and confidence map embedded in the same file.

These let you offer specialized blurs and bokeh options in your app.

Create Your First App

Dynamic Depth is an open format for the ecosystem and we're working with our partners to bring it to devices running Android 10 and later. With Dynamic Depth image you can offer specialized blurs and bokeh options in your app. Audio playback capture - Now any app that plays audio can let other apps capture its audio stream using a new audio playback capture API. In addition to enabling captioning and subtitles, the API lets you support popular use-cases like live-streaming games. Read more in our blog post.

New audio and video codecs - Android 10 adds support for the open source video codec AV1 , which allows media providers to stream high quality video content to Android devices using less bandwidth.

Give it a try with the sample app and source code here. Vulkan everywhere - Vulkan 1. We already see significant momentum on Vulkan support in the ecosystem - among devices running Android N or above, over half support Vulkan 1. With the new requirement in Android 10, we expect to see adoption rise even further in the coming year. The network connection APIs make it easier to manage IoT devices over local Wi-Fi, for peer-to-peer functions like configuring, downloading, or printing. The network suggestion APIs let apps surface preferred Wi-Fi networks to the user for internet connectivity.

Wi-Fi performance modes - Apps can now request adaptive Wi-Fi by enabling high performance and low latency modes. These can be a great benefit where low latency is important to the user experience, such as real-time gaming, active voice calls, and similar use-cases. The platform works with the device firmware to meet the requirement with the lowest power consumption.

ART optimizations - Improvements in the ART runtime help your apps start faster, consume less memory, and run smoother -- without requiring any work from you. At runtime, Generational Garbage Collection makes garbage collection more efficient in terms of time and CPU, reduces jank, and helps apps run better on lower-end devices. This chart shows the percentage improvement in startup time for specific apps when tested using Play profiles. This chart shows the percentage improvement in startup time for specific apps when tested using Play profiles. Neural Networks API 1. This lays the foundation for accelerating a much greater range of models -- such as those for object detection and image segmentation.

Android 10 is also the first release to support Project Mainline officially called Google Play system updates , our new technology for securing Android users and keeping their devices fresh with important code changes - direct from Google Play. For developers, we expect these updates in Android 10 to help drive consistency of platform implementation broadly across devices, and over time bring greater uniformity that will reduce your development and testing costs. Getting apps tested and ready for the new version of Android is crucial to faster platform updates throughout the ecosystem , so please prioritize this work if possible.

Next, when you're ready, dive into Android 10 and learn about the new features and APIs that you can use. Here are some of the top features to get started with. To read about all of the new features and changes, visit the Android 10 developer site. Then follow these instructions to configure your environment.

Android 10 will begin rolling out today to the three generations of Pixel phones -- Pixel 3 and 3a , Pixel 2, and even the original Pixel! If you own a Pixel device, watch for your official over-the-air update coming soon! As always, the system images for Pixel devices are available here for manual download and flash, and you can get the latest Android Emulator system images via the SDK Manager in Android Studio.

If you're looking for the Android 10 source, you'll find it here in the Android Open Source Project repository under the Android 10 branches. We'll soon be closing the Android Beta issue tracker and Feedback app, but please keep the feedback coming! Thanks again to the many developers and early adopters who participated in the Android Beta program this year!

You gave us great feedback, and filed thousands of issues that helped us to make the Android 10 platform great for consumers and developers. In May, we launched new Families policies to provide additional protections for children and families on Google Play. Thanks to everyone who has completed it already. Apps that include children in their target audience need to adhere to our new policy requirements including appropriate content, showing suitable ads learn more , and disclosing personally identifiable information correctly.

Apps who submit inaccurate responses in the target audience and content section will also be subject to these reviews. We respect that you are running a business and longer review times can impact how you work. Our goal is to prepare you for this change and minimize disruptions for you.

These apps will be subject to extended reviews for every update, and you may need to update your processes to accommodate for additional review time. Suggestions for how to best adapt to this change include submitting your app at least a week before any important launch dates and unless urgent avoid resubmitting your app while it is under review.

These changes help make the Play Store safer through deeper and longer reviews, which is a tradeoff we think everyone is willing to make. Thanks for your continued support in building a positive and safe experience for all users on Google Play. It is for this reason that we offer a broad range of vulnerability reward programs, encouraging the community to help us improve security for everyone. In these scenarios, Google helps responsibly disclose identified vulnerabilities to the affected app developer. This opens the door for security researchers to help hundreds of organizations identify and fix vulnerabilities in their apps.

If the developers already have their own programs, researchers can collect rewards directly from them on top of the rewards from Google. We encourage app developers to start their own vulnerability disclosure or bug bounty program to work directly with the security researcher community. Affected app developers are notified through the Play Console as part of the App Security Improvement ASI program, which provides information on the vulnerability and how to fix it.

Over its lifetime, ASI has helped more than , developers fix more than 1,, apps on Google Play. In alone, the program helped over 30, developers fix over 75, apps. The downstream effect means that those 75, vulnerable apps are not distributed to users until the issue is fixed. With these changes, we anticipate even further engagement from the security research community to bolster the success of the program. In particular, the program aims to identify situations where user data is being used or sold unexpectedly, or repurposed in an illegitimate way without user consent.

If data abuse is identified related to an app or Chrome extension, that app or extension will accordingly be removed from Google Play or Google Chrome Web Store. In the case of an app developer abusing access to Gmail restricted scopes, their API access will be removed. As continues, we look forward to seeing what researchers find next.

Thank you to the entire community for contributing to keeping our platforms and ecosystems safe. Happy bug hunting! The Google Play Store has over two billion monthly active users coming to find the right app, game, and other digital content. There are now two distinct destinations for games and apps, which helps us better serve users the right kind of content. Once users find the right app or game, the updated store listing page layout surfaces richer app information at the top of each page as well as a more prominent call-to-action button.

This makes it easier for users to see the important details and make a decision to install your app. To ensure your page resonates well with Android users, use store listing experiments to test for the best app icon, images, video, and descriptions on Google Play.

You can also tailor your marketing messages to specific user groups based on their country, install state or even pre-registration by creating custom store listings. For even more, try our free e-learning resource, Academy for App Success. Docs News. Android Developers Blog.
