can't switch between tabhost with google map inside

Question

I used a tabhost for two fragments. Each fragment contains a google map.The question is it performs well in each fragment, but when I switch back the same fragment it crushed.
This is the error messages:

I've found many solutions on web. Every one told that I have to remove fragment in onDestroy(), but it still not work on me.

This is my fragment content:

 View v;

  @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        if (container == null) {
            return null;
        }            
        if(v!=null){
            ViewGroup parent = (ViewGroup) v.getParent();
            if (parent != null)
                parent.removeView(v);
        }
        /*------------------this is line 263 that caused error----------*/
        v = inflater.inflate(R.layout.allfragment, container, false);
        Bundle args = getArguments();
        if (args != null && args.containsKey(ARGUMENT_NAME)) {
            String text = args.getString(ARGUMENT_NAME);
            if (mMap == null) {
                mMap = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.allmap)).getMap();
            }
            if (mMap != null) {
                if(text.equals("all")){
                    setUpAllMap();
                }
                else if(text.equals("art")){
                    setUpArtMap();
                }
            }



@Override
    public void onDestroyView()
    {
        super.onDestroyView();
        killOldMap();
        mMap = null;
    }
    private void killOldMap() {
        SupportMapFragment mapFragment = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.allmap));
        if(mapFragment != null) {
            FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
            ft.remove(mapFragment);
            ft.commit();
        }
    }

I've tried many solutions on web but the problem still remains.Could anyone help me with this problem?
Thanks a lot!

Have you tried adding the following code to your map fragment? Maybe you have omit something? If you haven't tried, please give it a shot.

public void onDestroyView() {
    super.onDestroyView();
    FragmentManager fm = getActivity().getSupportFragmentManager();
    Fragment fragment = (fm.findFragmentById(R.id.map));
    FragmentTransaction ft = fm.beginTransaction();
    ft.remove(fragment);
    ft.commit();
}
