Answer 1

Try this code

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

and in the manifest.xml

<application android:icon="@drawable/icon" android:label="@string/app_name">′
    <activity android:name="XXXXX"
              android:label="@string/app_name"
              android:configChanges="keyboard|keyboardHidden|orientation|screenSize"> //this <--
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    ...
</application>

EDIT: I added the screenSize flag. In android >3 if you dont add this flag the method onConfigurationChanged will not be called.
