Very useful thread, thanks a lot! I'm using a similar solution like yours, the difference is that my "finish();" is located in onStop. So it is only finished when it can not be seen from the user, I feel this is a little bit better than onPause.
they say "Prior to 2.0 multiple surfaces on top of each other were not supported, and any tricks you use to try to make this work are likely to break in the future or on different devices." This is exactly what I'm worrying about...
