[Interest] Fwd: How to shutdown Qt app on Android.

[Igor Mironchik]

Thank you for your suggestion.

I have tested QApplication::quit() in  
QCoreApplication::applicationStateChanged( Qt::ApplicationSuspended ).

And yes, the app is still in the list, but when I launch the app again it  
starts from the same beginning, not resumed...

Seems that approach with applicationStateChanged() workes...

Thank you guys.
