Test Devices About the Android is an open source operating system for mobile devices and a corresponding open source project led by Google. This site and the (AOSP) repository offer the information and source code needed to create custom variants of the Android OS, port devices and accessories to the Android platform, and ensure devices meet the compatibility requirements that keep the Android ecosystem a healthy and stable environment for millions of users. As an open source project, Android’s goal is to avoid any central point of failure in which one industry player can restrict or control the innovations of any other player. To that end, Android is a full, production-quality operating system for consumer products, complete with customizable source code that can be ported to nearly any device and public documentation that is available to everyone (in English at source.android.com and in Simplified Chinese at source.android.google.cn ). Just as you can contribute code to AOSP , you can also contribute to AOSP documentation—and we want your input! Android’s flexibility and ever-changing codebase means this site needs your feedback to keep content fresh, accurate, and relevant to Android implementors. We encourage you to check the changelog for details on recent AOSP updates and to report bugs or offer suggestions using the Site Feedback at the bottom of every page (or by visiting g.co/androidsourceissue ).
