About the Android Open Source Project

Android is an open source software stack for a wide range of mobile devices and a corresponding open source project led by Google. This site and the Android Open Source Project (AOSP) repository offer the information and source code you need to create custom variants of the Android stack, port devices and accessories to the Android platform, and ensure your devices meet compatibility requirements.

We also wanted to make sure there was no central point of failure, where one industry player could restrict or control the innovations of any other. The result is a full, production-quality operating system for consumer products with source code open for customization and porting.

As the AOSP documentation site, we seek your contributions. With an ever-changing ecosystem, we need your help to stay fresh. You may make your own fixes directly to the source files by following the instructions in our README. You may also use the Site Feedback link at the bottom of any page to report bugs and offer suggestions for enhancement. See the site’s changelog for a detailed view of all updates.
