Assam,
Thank you very much for your reply. It helped a lot.
Unfortunately I’m still having the same crash when launching the application and I don’t know what this means:
E AndroidRuntime: FATAL EXCEPTION: main
E AndroidRuntime: Process: com.imaginando.drc, PID: 2776
E AndroidRuntime: java.lang.RuntimeException: Unable to pause activity {com.imaginando.drc/org.qtproject.qt.android.bindings.QtActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void org.qtproject.qt.android.QtDisplayManager.unregisterDisplayListener()' on a null object reference
E AndroidRuntime: at android.app.ActivityThread.performPauseActivityIfNeeded(ActivityThread.java:4031)
E AndroidRuntime: at android.app.ActivityThread.performPauseActivity(ActivityThread.java:3986)
E AndroidRuntime: at android.app.ActivityThread.handlePauseActivity(ActivityThread.java:3938)
E AndroidRuntime: at android.app.servertransaction.PauseActivityItem.execute(PauseActivityItem.java:45)
Can you please enlighten me?
Thank you!
Best regards,
Nuno
