android - App crashes when bringing the app to foreground while playing high memory games -

I have a bizarre problem with my app

When I use high memory consumption games like applet 8 I play, my app moves from the background to the foreground, the app crashes This is when I play high memory app like Asphalt 8 . Crashing is because the activity references to zero

I do not know how to fix it.

UPDATE
