Android onStop onDestroy called after onCreate

Question

I hope you can help me. I don't understand why this is happening to me.

My app is calling onPause(), onStop(), onDestroy() immediately after calling onCreate(). The screen is black. When I press the home button, onPause(), onStop(), onRestart(), onStart() and onResume() are called and everything is fine. This only happens on my real device (xperia z2, kitkat 4.4.2). This does never happen on my tablet (galaxy tab3, 4.x) and many other emulators.

Have you guys a solution for that problem? Thank you very much.

Here's the Logcat:

Edit: That was all the logcat throws out. I just found out, that when I hold the device in landscape, it won't call onDestroy().

I implemented:

@Override
public void onConfigurationChanged(Configuration newConfig) 
{
    super.onConfigurationChanged(newConfig);
}

and android:configChanges="orientation|keyboardHidden"

... but still got the same problem.

Answer 1

You're calling setRequestedOrientation to landscape as soon as you start your Activity (onCreate). The documentation states

Change the desired orientation of this activity. If the activity is currently in the foreground or otherwise impacting the screen orientation, the screen will immediately be changed (possibly causing the activity to be restarted). Otherwise, this will be used the next time the activity is visible.

So... you pretty are seeing the expected behavior of your Activity.

If what you want to do is lock your screen to landscape mode, you could, for instance handle it like this:

<activity android:name="GameActivity "
android:screenOrientation="landscape"
android:configChanges="keyboardHidden|orientation|screenSize">

</activity>

which would prevent the screen configuration changes from triggering the events that you mentioned.
