public class ImagePagerActivity extends BaseActivity { 

    private static final String STATE_POSITION = "STATE_POSITION"; 

    ViewPager pager; 

    public void onCreate(Bundle savedInstanceState) { 
     // ... 

     if (savedInstanceState != null) { 
      pagerPosition = savedInstanceState.getInt(STATE_POSITION); 
     } 

     // ... 

     pager.setCurrentItem(pagerPosition); 
    } 

    public void onSaveInstanceState(Bundle outState) { 
     outState.putInt(STATE_POSITION, pager.getCurrentItem()); 
    } 

    ... 
}
