Crash due to quick Back button press

Question

When I press the Back button once, the app exits just fine. But when I press the [Back] button repeatedly and quickly, the app crashes (ref.the attached stack trace). There happens even without any fragment transaction performed. Is there a cure for this?

@SankarV I tried all methods provided at the SO link to no avail. Then I figure out my stupid mistake (mentioned in the edit). Thank for the link then. That question seems old (from Sep 2011) so I guess Google had already fixed all the described bugs. — An Hoa, Apr 07 '13 at 03:33

Just figure out my stupid mistake. I called super.onStop() when overriding the activity's onPause()!
