Thanks, but why not simply add

android:configChanges="keyboardHidden|orientation|screenSize"

to the manifest:

<activity
            android:name=".AboutActivity"
            android:label="@string/title_activity_about"
            android:parentActivityName=".MainActivity">
            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".MainActivity" />
</activity>
