After about 2 weeks of work on a project of an App Android / iOS already published on the App Store and Google Play I found the following errors:

1 - If I compile the project target device debugging the app works perfectly if it is in the foreground all goes well for hours while if I leave in the background debugging ends after a few hours  and the compiler returns to stop mode but the app is still running on device.

2 - If I compile the project target device debugging the app works perfectly close the compiler I disconnect the device and I'm going to do anything else with the device leaving the app in the background the app suddenly stops and the absurd and very serious since that time will not start again.When I try to start the app you only see a black screen


Same sources compiled for iOS work perfectly for days never stops.

I am very disappointed and angry in this state is difficult to work and produce good work I hope someone has some advice to get around the problem.

Bye All
