There are generally three ways to do this:

1. As some of the answers suggested, you could distinguish the cases of your activity being created for the first time and being restored from savedInstanceState. 
   This is done by overriding onSaveInstanceState and checking the parameter of onCreate.

2. You could lock the activity in one orientation by adding android:screenOrientation="portrait" (or "landscape") to <activity> in your manifest.

   <activity android:screenOrientation="landscape">

3. You could tell the system that you meant to handle screen changes for yourself by specifying android:configChanges="screenOrientation" in the <activity> tag.
