Android: Updates to handling screen orientation changes

Beginning with Android 3.2 (API level 13), the “screen size” also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the “screenSize” value in addition to the “orientation” value. That is, you must decalare android:configChanges=”orientation|screenSize” in your android manifest file.

However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).
