[android help] Blank Map Screen Open while using Google Maps Api v2

I am trying to use Google Maps Api V2 and following all the steps in Android Google Maps Article

But after all steps, code is executed on my glaxy young with android 2.36 but blank map screen is displayed

My main activity code is

  protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.showmapactivity_layout);
FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment mySupportMapFragment 
 = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
map = mySupportMapFragment.getMap();

//map = getFragmentManager().findFragmentById(R.id.map)).getMap();
Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
    .title("Hamburg"));
Marker kiel = map.addMarker(new MarkerOptions()
    .position(KIEL)
    .title("Kiel")
    .snippet("Kiel is cool")
    .icon(BitmapDescriptorFactory
        .fromResource(R.drawable.ic_launcher)));

// Move the camera instantly to hamburg with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
}
