That's too bad. I do know you can trap the backKey message but for some 
reason we don't get a homeKey message.

I used to worry about it, but after running a lot of Android apps I've 
noticed that most of them just pick up where they left off if they are 
still in memory, or else they start over again if they aren't. It must 
be a common problem. But that doesn't help you much if you need to do 
processing no matter how the user leaves.

I'm guessing the OS probably doesn't notify the app that it's suspended.
