Mapapi v2 in android causing error in fragment

Question

I am having little problem in map implementation in fragment. Below is my code.

import android.app.Fragment;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.CameraPosition;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import com.tfick.android.R;

public class PoiFragment extends Fragment{

private GoogleMap mGoogleMap;

private static final LatLng SYDNEY = new LatLng(23.03,72.62);

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View v=inflater.inflate(R.layout.poi_fragment, container,false);


    MapFragment  mMapFragment = MapFragment.newInstance();
     FragmentTransaction fragmentTransaction =
             getFragmentManager().beginTransaction();
     fragmentTransaction.add(R.id.container1, mMapFragment);
     fragmentTransaction.commit();

     if(mGoogleMap ==null){

            /*initializing map */

            mGoogleMap=mMapFragment.getMap();

            /*cretaing custom camera position*/

            CameraPosition mCameraPosition=new CameraPosition.Builder().target(SYDNEY).bearing(0).tilt(30).build();

            /*setting custom camera position*/

            mGoogleMap.animateCamera(CameraUpdateFactory.newCameraPosition(mCameraPosition));

            /*adding custom marker on the map.*/
             mGoogleMap.addMarker(new MarkerOptions().draggable(true).position(new LatLng(22.03, 72.56)).title("hello world").snippet("Ahmedabad").icon(BitmapDescriptorFactory.fromResource(R.drawable.wifi)));

            mGoogleMap.addMarker(new MarkerOptions().draggable(true).position(new LatLng(23.03, 78.10)).title("hello world").snippet("Baroda").icon(BitmapDescriptorFactory.fromResource(R.drawable.wifi)));

        }

        if(mGoogleMap !=null){


            /* map is already initialized then setting map type */
            /*
             * normal 
             * satellite
             * hybrid
             * terrain
             * none
             */
            mGoogleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

        }

    return v;
}
}

Thanks to me i find the solution if any once have same problem use following code.

import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.CameraPosition;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import com.tfick.android.R;

public class PoiFragment extends MapFragment {
    /*object of google map*/
    public GoogleMap mGoogleMap;
    /* summy location*/
    private static final LatLng SYDNEY = new LatLng(23.03, 72.62);


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        return super.onCreateView(inflater, container, savedInstanceState);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onActivityCreated(savedInstanceState);

        if (getMap() != null) {
            Log.d(getClass().getSimpleName(), "Map ready for use!");

            mGoogleMap = getMap();

            /* cretaing custom camera position */

            CameraPosition mCameraPosition = new CameraPosition.Builder()
                    .target(SYDNEY).bearing(0).tilt(30).build();
            Log.i("gmap", mGoogleMap.toString());

            /* setting custom camera position */

            mGoogleMap.animateCamera(CameraUpdateFactory
                    .newCameraPosition(mCameraPosition));

            /* adding custom marker on the map. */
            mGoogleMap
                    .addMarker(new MarkerOptions()
                            .draggable(true)
                            .position(new LatLng(22.03, 72.56))
                            .title("hello world")
                            .snippet("Ahmedabad")
                            .icon(BitmapDescriptorFactory
                                    .fromResource(R.drawable.wifi)));

            mGoogleMap
                    .addMarker(new MarkerOptions()
                            .draggable(true)
                            .position(new LatLng(23.03, 78.10))
                            .title("hello world")
                            .snippet("Baroda")
                            .icon(BitmapDescriptorFactory
                                    .fromResource(R.drawable.wifi)));

        }

    }
