Are you trying to inflate a fragment... inside a fragment_layout?

Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically.

Please see this post.

Simple answer! you check if view is already created in fragment then return else add like this

GoogleMap fragmentMap;

if(fragmentMap==null)

     fragmentMap = ((com.google.android.gms.maps.MapFragment) getActivity().getFragmentManager().
     findFragmentById(R.id.mapfragment)).getMap();
