use activity life cycle methods to save the state of the Activity and restore the Activity state to the previous state. those methods are onPause(), onResume() http://developer.android.com/reference/android/app/Activity.html follow this link

You can override the onSaveInstanceState and onRestoreInstanceState methods in the Activity class and save/restore the value of your index.
