App crashes when inactive on background, after screen locking

[KelvinNovais]

Issue explanation (write below this line)

Context: I use this app to access some PDFs for reading. Naturally when I open the file, Amaze goes to the background. If after sometime the screen get locked or I do that myself, the following crash is reported when unlocking the screen.

I tried to figure out more precisely the causes, but I only can highlight these 3 conditions:

1. The app is running on the background;
2. It's inactive for some time;
3. The screen got locked.
