Android has led the way towards the future of mobile, with new technologies like 5G to foldable displays to machine learning built into the core. A hallmark of our approach is a strong developer community that provides early and thoughtful feedback, helping us deliver a robust platform for apps and games that delight billions of users around the world. So today, we’re releasing the first Developer Preview of Android 11, and building on a strong feedback cycle last year, we’re making this year’s preview available to you earlier than ever.
With Android 11 we’re keeping our focus on helping users take advantage of the latest innovations, while continuing to keep privacy and security a top priority. We’ve added multiple new features to help users manage access to sensitive data and files, and we’ve hardened critical areas of the platform to keep the OS resilient and secure. For developers, Android 11 has a ton of new capabilities for your apps, like enhancements for foldables and 5G, call-screening APIs, new media and camera capabilities, machine learning, and more.
This is just a first look; like prior years, we’ll continue to share new features and updates over the coming months and into Google I/O as we work through your feedback. The most important thing for you to do right now is this: visit the Android 11 developer site, download a system image for your Pixel 2, 3, 3a, or 4 device, and let us know what you think!
Today’s release is an early baseline build for developers only and not intended for daily or consumer use, so we're making it available by manual download and flash only. Remember, getting early input from you is crucial in helping us evolve the platform to meet your needs. Read on for a taste of what’s new in Android 11, and visit the developer site for details on timeline, how to test, and how to give feedback.
5G brings consistently faster speeds and lower latency to more users around the world. With 5G you can extend your Wi-Fi app experiences -- such as streaming 4K video or loading higher-res game assets -- to mobile users, or you can build new experiences designed specifically for 5G. In Android 11 we’re enhancing and updating the existing connectivity APIs so you can take advantage of 5G’s improved speeds.
Moving beyond the home, 5G can for example let you enhance your “on-the-go” experience by providing seamless interactions with the world around you from friends and family to businesses.
Device makers are continuing to innovate by bringing exciting new form-factors and device screens to market. We’ve extended support for these in the platform, with APIs to let you optimize your apps.
Communicating with your friends and colleagues is the most important thing many people do on their phones. In Android 11, we are introducing changes that help developers create deeper conversational experiences, a few of which you’ll see early versions of in DP1:
Neural Networks API (NNAPI) is designed for running computationally intensive operations for machine learning on Android devices. In Android 11, we’re expanding the operations and controls available to developers. In this release, we’ve added new operations and execution controls to help optimize common use cases:
See the NDK sample code for examples using these new APIs.
Watch for more coming in later preview updates. We’re working with hardware vendors and popular machine learning frameworks such as TensorFlow to optimize and roll out support for NNAPI 1.3.
Privacy has always been at the core of Android, and each year we’ve added more ways to keep users secure and increase transparency and control. These changes have been popular with users - for example in Android 10 we added the “While app is in use” permission option to give users more granular control over their location and limit background location access. So far, when given the “While app is in use” option, about half of users select it.
In Android 11 we’re continuing our focus on user privacy with new permission options, updates to scoped storage, and more. Please give these features a try with your apps right away and let us know what you think.

In addition to these platform changes, users tell us that they want more protection on earlier versions of Android and more transparency around how apps will use this data, so we are updating Google Play Policy to ensure that apps only request location permissions when truly necessary. Read more
We focus on raising the bar for security with each version of Android -- from reaching more devices with monthly security updates to building more protections into the latest platform. In Android 11, we’ve extended Android’s defense-in-depth strategies to more areas of the platform and added new features and APIs for apps.
Since Android 10, we’ve been scaling up our investment in Google Play System Updates (Project Mainline) to improve security, privacy, and consistency across the ecosystem. Thanks to strong collaboration with device makers, we’ve made significant progress towards this goal and have expanded our infrastructure to reach a wider range of devices more safely and quickly.
In Android 11, we’ve added 12 new updatable modules, for a total of 22 modules. Highlights include a permissions module that standardizes user and developer access to critical privacy controls on Android devices, a media provider module that’s integral to our privacy efforts around Scoped Storage, and an NNAPI (Neural Networks API) module that optimizes performance and guarantees consistent APIs across devices. To learn more about Google Play System Updates, check out the Project Mainline blog post.
We’re also working to make updates faster and smoother by prioritizing app compatibility as we roll out new platform versions. In Android 11 we’ve added new processes, developer tools, and release milestones to minimize the impact of platform updates.

The Developer Preview has everything you need to try the Android 11 features, test your apps, and give us feedback. To get started, download and flash a device system image to a Pixel 2 / 2 XL, Pixel 3 / 3 XL, Pixel 3a / 3a XL, or Pixel 4 / 4 XL device. Additionally, you can set up the Android Emulator through Android Studio. The Android Emulator running Android 11 system images includes experimental support to run ARM 32-bit & 64-bit binary app code directly on 64-bit x86 Android Emulator system images. Lastly, for broader testing, GSI images are also available.
Next, update your Android Studio environment with the Android 11 Preview SDK and tools - you can do this from inside Android Studio. See the setup guide for complete details. To take advantage of the latest Android Studio features, we recommend installing the latest version of Android Studio from the canary channel.
When you’re set up, here are some of the things you can do:
For more information, visit the Android 11 developer site. You’ll find an overview of what’s new in this release, details on behavior changes, setup and migration guides, release notes, feedback channels, and more.
We plan to update the preview system images and SDK regularly throughout the Android 11 release cycle. This initial preview release is for developers only and not intended for daily or consumer use, so we're making it available by manual download and flash only. Downloads are here and instructions are here.
As we get closer to a final product, we'll be inviting consumers to try it out as well, and we'll open up enrollments through Android Beta at that time. Stay tuned for details, but for now please note that Android Beta is not currently available for Android 11.
As always, your feedback is crucial, so please let us know what you think — the sooner we hear from you, the more of your feedback we can integrate, and because of timelines, we’re giving priority to input we receive in the next several weeks. When you find issues, please report them here.
