Android: Use DisplayListener to detect rotation

Browse Source 
Since Activity's onConfigurationChanged is not called
when rotating from landscape to landscape (through 180 degrees),
added display listener to detect the rotation.

DisplayManager.DisplayListener.onDisplayChanged() is called exactly when
Display.getRotation() value is changed.

Task-number: QTBUG-56919
