You can't handle swipe, because system just removes your process from memory without calling any callback.
I have checked, that before user calls "recent apps" screen, onPause() will be always called. So you need to save all data in onPause method without checking isFinishing().
To check back button, use onBackPressed method.

To check back button, use [onBackPressed](http://developer.android.com/reference/android/app/Activity.html#onBackPressed()) method.
