It have been long time since this question have been active, but I sill need to answer this. I had same issue and found answer.

In manifest you should add android:configChanges=orientation|screenLayout|layoutDirection|screenSize in your activity which should not call default actions on orientation change.

...
<activity android:name=".Activity"
  android:screenOrientation="portrait"
  android:configChanges="orientation|screenLayout|layoutDirection|screenSize" 
...

And in your activity:

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
    // This overrides default action
}

I had to add "|screenSize" as well for more recent OSs. – Jake Brownson Feb 06 '14 at 19:48
Yes, basically add any parameter that might be related to or caused by orientation change. – Karri Rasinmäki Feb 07 '14 at 20:54

Edited answer so that "screenSize" is in parameter list as well. – Karri Rasinmäki Mar 03 '15 at 11:43

This is the default behavior: the activity is recreated when orientation changes. But you can decide to ignore this event. You can find details here : How to make an application ignore screen orientation change?

Well, the technique in the linked article apparently prevents orientation changes, but not the calls to the callbacks when the orientation changes (which is what was asked). – Heiko Rupp Feb 25 '12 at 12:26

You can't avoid that, those are system callbacks. You can save the state though in onStop and then have the system pass it to onCreate for a faster recovery of the state after the screen orientation has changed.

See also this and that article on the developer pages.

This can avoided by calling android:configChanges="orientation|keyboardHidden" . But still there are some issues – indira May 12 '11 at 06:53
