title: Switching fragments - Google Map Fragment V2 - Activity has been destroyed Error
body: <p>I have a Maps Activity (SherlockFragmentActivity) that loads in a Maps Fragment that has 2 buttons and switches between showing 2 different fragments (GoogleMapFragment &amp; ScaleImageViewFragment)</p>
  
  <p><img src="https://i.stack.imgur.com/F0sWE.png" alt="Screen Shot"> </p>
  
  <p>When I click the Exhibitor Map button it replaces the fragment, however when I click back I get an "java.lang.IllegalStateException: Activity has been destroyed" error</p>

  <p>and my GoogleMapFragment.java file:</p>
  
  <pre><code>public class GoogleMapFragment extends Fragment {
  private SupportMapFragment mMapFragment;

      }
  }
  }
  </code></pre>
  
  <p>I have been banging my head against the wall for quite some time trying to figure out this error and how to avoid/fix it.</p>
  
  <p>Update:</p>
  
  <p>by the way if I switch to:</p>
  
  <pre><code>getActivity().getSupportFragmentManager()
              .beginTransaction()
              .add(R.id.map_holder, mMapFragment)
              .commit();
  </code></pre>
  
  <p>in the GoogleMapFragment then I dont get the Error, but I cant get a hold of the map to set the maker... it seems like a race condition</p>
