Android: simulate long running time

Question

I guess everybody experienced his app work great when you try it for a quick 30 minutes. But when an app sits in the background of the device for a day or so, you get your NullPointerExceptions and things don't work as expected because the Garbage Collector stole your stuff. Is there any way to simulate an app running for a long time in the background?

Answer 1

Settings -> Developer options -> Background process limit -> At most 1 process.

Don't forget to set it back when you're done having fun. Cheers.
