You can try the below code :

 @Override
 public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    Log.i("onActivityCreated", "onActivityCreated");
    if(supportMapFragment==null){
        supportMapFragment = (SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map);

        supportMapFragment.getMapAsync(new OnMapReadyCallback() {
           @Override
             public void onMapReady(GoogleMap googleMap) {
             mGoogleMap = googleMap;

            loadMapAtPosition(googleMap, CAMERA_INITIAL_LATITUDE, CAMERA_INITIAL_LONGITUDE);
        }
    });
 }

.....

private void loadMapAtPosition(GoogleMap googleMap, double latitude,    double longitude){     googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude), 6.0f)); }

Just Simple if you want to use Map in Fragment.

Try this

in you Fragment class.

 GoogleMap map = ((SupportMapFragment) getFragmentManager()
                .findFragmentById(R.id.map)).getMap();

and in your xml.

<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment" />

if you use google map within fragment then you should be use map object like this.you have to use getChildFragmentManager() to find fragment

    <fragment
        android:id="@+id/main_map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" >
    </fragment>

     SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager()
                    .findFragmentById(R.id.main_map);
