error with google maps v2 in tab (MapFragment in Fragment)

问题

I have a fragmentActivity where I build a tabHost and in each tab there is a Fragment. Well, I haver four tabs 3 with info and 1 with a fragment where is included a google-map-v2 (is a fragmentMAp in a Fragment because I want to add buttons etc.), when I select one tab and pass to other everything go well, but when I select the map tab, after that other tab and again the map tab an error is throw.

My view seems like:

|__||__|__|__|
| __________ |
|| FRAGMENT ||
||_____   _ ||
|| FRAG| |_|||
|| MAP |    ||
||     |    ||
||_____|    ||
||__________||

The error:

Here is the problem, but I dont know why only this fragment have the problem:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.monumenos_view_preview, container, false);


return view;
}

回答1:

Finally I found the solution, I removed the nested MapFragment in my Fragment:

public void onDestroyView ()
{
      try{
    SupportMapFragment fragment = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapv2));
        FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.remove(fragment);
        ft.commit();
      }catch(Exception e){
      }
    super.onDestroyView();  
}

I get the solution from here: Fragments within Fragments
