Think of home like alt-tab in windows.  You never need to capture it.
You just need to handle onPause()/onStop() in a way that makes sense
for the user temporarily leaving your app.  You'll get onFinish() when
your app is to be actually destroyed.  If you have a need to actually
kill off the whole thing when home is pressed, call finish() in
onPause()/onStop() and you shall receive the touch of the droid
reaper, making for a clean start next time the user tries to enter the
activity.
