Subject: [PATCH] altosdroid: Hack up build to 'work' for now

Android apps are now build with gradle instead of ant; the ant bits
are stale and only work with old java. Use old java to run ant while
using the current java compiler to build things.

This requires a custom version of the google play API library.
