The app is C++ calling some java functions, all encapsulated in a class extending org.qtproject.qt5.android.bindings.QtActivity

I am already creating the QApplication in the main() function so I see no way to fix that.

Until now all was running fine anyway but with Android 5 the app does not start. The error is not explicitly there but later there's an exception

bq. java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

when calling QAndroidJniEnvironment::RegisterNatives. that souns very likely to be related.

Has anyone experienced something similar? (I've seen similar threads but not one related to android + calling java)

Thanks!
