I'm inserting Fragments into the Activity using this 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();
}
}
Fragments code is:
public class SimpleFragment extends ListFragment
{
@Override
public void onActivityCreated(Bundle savedInstanceState)
{
super.onActivityCreated(savedInstanceState);
getView().setBackgroundColor(Color.YELLOW);
}
}
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.
It seems that after rotation FragmentManager didn't restores
animations (enterAnim, exitAnim, popEnterAnim and popExitAnim) for
BackStackEntry.
FragmentManager dump (without rotation):

Is this Android behavior or I'm doing something wrong?
Thank you for any help!
