I work on a very popular app in Latin America. That means we get to experience every single edge case in the eco system. My favorite quirk has been that for some reason I will never understand when an app goes into a full screen ad it can make your main activity eligible for GC. That means that you don't get any of your Activity life cycle events. Just a lone finalize and your app is gone. Then when the video ad is done you get a truly spectacular crash!

Sadly, I have a half dozen different ways activities have found to explode themselves. It makes me sad!

Sounds like the video ad is a new activity? Since it's full screen, your main activity is no longer visible so you should be seeing onPause and onStop fire. Are you saying you don't see them?

Also, I'd imagine video ads are also quite memory intensive, so if a low-RAM device is playing one I wouldn't be surprised if Android has to kill some processes (like your activity that was sent to the background) to make space.

Perhaps you should look into what these video ads are doing and what sort of resources they eat up?
