You realize that you need to save and restore your state to work correctly
anyway, right? If you don't, you will lose your state when the user returns
to it after it was killed in the background.
So do that first. Seriously. You have to do it anyway.
Then once you have that working, you can look at using android:configChanges
or onSaveNonInstanceState(), both of which are ONLY optimizations on top of
the general save/restore model.
