title: Fragment lost transition animation after configuration change
body: <p>I'm inserting Fragments into the Activity using this code:</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) 
  {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
  
      FragmentManager fm = getFragmentManager();
      String tag = "simple";
  
      Fragment fr = fm.findFragmentByTag(tag);
      if (fr == null)
      {
          SimpleFragment simpleFragment = new SimpleFragment(); 
          FragmentTransaction transaction = fm.beginTransaction();
          transaction.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out,
                                          android.R.animator.fade_in, android.R.animator.fade_out);
          transaction.add(R.id.main_layout, simpleFragment, tag);
          transaction.addToBackStack(tag);
          transaction.commit();
      }
  }
  </code></pre>
  
  <p>Fragments code is:</p>
  
  <pre><code>public class SimpleFragment extends ListFragment 
  {
      @Override
      public void onActivityCreated(Bundle savedInstanceState) 
      {
          super.onActivityCreated(savedInstanceState);
          getView().setBackgroundColor(Color.YELLOW);
      }
  }
  </code></pre>
  
  <p>When I pop the fragment from backstack via Back button just after launching, then everything is fine and I can see fade out animation. But if I rotate device and press Back button then fragment disappears without animation.</p>
  
  <p>Is this Android behavior or I'm doing something wrong?</p>
  
  <p>EDIT:
  It seems that after rotation FragmentManager didn't restores animations (enterAnim, exitAnim, popEnterAnim and popExitAnim) for BackStackEntry.</p>
  
  <p>FragmentManager dump (without rotation):</p>
