I have an activity that makes use of a surfaceview forced into landscape mode using "android:screenOrientation="landscape"" in the manifest file. My concern is related to the use case where the screen is turned off using the (red) hangup button, where I would assume that the onPause() method of the activity would be invoked and nothing else. However as can be seen from the bottom trace, the activity is cycled twice. I have tried to summarize the relevant part of the trace - the numbers are marked in the complete bottom trace succeeding an empty line.
1) onSaveInstanceState() + onPause() are invoked 2) windowManager reports rotation and config changed, causing surfaceChanged() to be invoked (I assume) 3) onDestroy() is invoked 4) onCreate() is invoked 5) onPause() is invoked 6) onResume() is invoked 7) onSaveInstanceState() + onPause() are invoked And please note that all this is caused by just one hangup key press - the handset being a HTC G1 running Android 1.5. I would like some feedback on the following concerns: a) Why is the activity being shut down? I would not expect it to be caused by the rotation/config changed (the handset has not even been rotated) due to the "screenOrientation=lanscape". b) Why is the activity being restarted, paused, resumed and then paused once again? Google has led me to the following posts that may be dealing with the same issue, however it seems as no firm conclusion has been drawn: http://code.google.com/p/android/issues/detail?id=2423 http://www.mail-archive.com/[email protected]/msg58374.html I hope you can help me here.
