I may have answered my main question by discovering that I can
override the dispatchTouchEvent method in my Activity. This gives me
events no matter what I'm interacting with. I just implemented:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
Log.e("UI","dispatchTouchEvent");

mHandler.removeCallbacks(mTimeoutHandler);
mHandler.postDelayed(mTimeoutHandler, 2000);

return super.dispatchTouchEvent(ev);
}

With this I am able to postpone the timeout while the user is
interacting, indefinitely. Then two seconds after they let go of the
screen, the timeout handler gets called back and it will fade out the
buttons. That'll probably solve my issues for now. Is this solution a
bad one for some reason?

Cheers,

Neal
