android_main() now takes an `app: AndroidApp` argument and has an extern "Rust" ABI instead of "C" ABI. This should help make it possible to run multiple native Activities in a single process.
This is a minimal test application similar to agdk-mainloop that
is based on NativeActivity instead of GameActivity.
It shows how to run a mainloop based on native_activity::poll_events() and
traces the events received without doing any rendering. It also saves and
restores some minimal application state.
Since this test doesn't require a custom Activity subclass it's
optionally possible to build this example with cargo apk.
The idea here is to test whether we can have a NativeActivity based
glue layer which is API compatible with game-activity, which can
optionally be used for very basic tests/demos that want the convenience
of not needing to compile any Java code.
