[Android-development] Android: crash in qmessagebox

[maitai]

Thanks Louis for replying

Concerning permissions I have been there too it's something specific to 
Android 6, and I had to implement a requestPermission method in Java. 
But since it's Android 5 I don't think it is that case (plus I cannot 
imagine that QMessageBox would need a permission that QDialog don't 
have).

I'll keep that in mind anyway

Philippe.
