There should be no need for anything as complicated as that huge 
android.toolchain.cmake file. CMake has a Modules/Platform/Android.cmake 
file, and cross compiling for Android should really be a case of specifying 
simple things local to you such as your compiler paths etc.

I filed 

 http://public.kitware.com/Bug/view.php?id=15492

for better documentation there (and to find out what features are missing in 
CMake which would make everything easier). If you know what is missing in 
CMake but required to make cross compiling for android simpler, please add 
it there.

Thanks,

Steve.
