      <p>
      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.
