The Android backend has been fairly unused, since we do not have projects actively using it. It gets basic build testing as part of the normal build, but runtime testing it takes a considerable effort, and so I have not done that in a long time. The code is slowly rotting, and with new emerging backends it starts to be a burden, since it cannot use udev, but needs evdev. Therefore to ease Weston going forward, remove the Android backend. If someone misses it, it can still be found in the stable 1.0 branch, and of course resurrected from git history if someone wants to put in the effort and maintain it.
