Stephe, you're talking apples to oranges.
We're talking about building native Ada applications which (like
native C/C++ applications) could utilize the Android API for windows,
accelerator sensor access, etc.  The binding with those libraries
still need to be made, and you need to wrap in the xml manifests
described in the "nativeactivity" capability that was introduced with
Android 2.3.

You're talking about building the apps in the Java VM I think, and
that's just an entirely different approach.

GNAT-AUX specifically targets x86, x86_64 on four BSDs and Solaris,
and ARM on Android.  It will very likely work on other platforms
(namely Linux) and even other processors, but that is just a carryover
from gcc and it's not tested.
Stock GCC/GNAT can not be built for Android/ARM, although it should
work fine for Linux/ARM.
