| Android is an open-source software stack for a wide range of mobile devices and a corresponding open-source project led by |
| Google. Here you can find the information and source code you need to learn more about the Android platform. From there you can |
| create custom variants of the Android software stack, port devices and accessories to the Android platform, |
| and ensure your devices are compatible with the Android compatibility definition. |
