Hi there. One of our goals in toolchain is to give good support to the Android group. I've written a page from the toolchain perspective on what is Android, how do you build it, and how you do common toolchainy tasks like reproduce a compiler fault: https://wiki.linaro.org/MichaelHope/Sandbox/AndroidAndToolchain
Comments are welcome. It needs sections on how the compiler is configured, running a program using adb, and basic debugging.
