This is my code which i have implemented in android java

public class MainActivity extends Activity 
{
private MapView mapView;
private MapController mapController;    
LocationManager locationManager;

ArrayList<OverlayItem> overlayItemArray;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mapView = (MapView)findViewById(R.id.mapview);

    mapView.setBuiltInZoomControls(true);
    mapView.setMultiTouchControls(true);
    mapView.setClickable(true);
    //mapView.setUseDataConnection(false);
    mapController = (MapController) mapView.getController();
    mapController.setZoom(17);

    //--- Create Overlay
    overlayItemArray = new ArrayList<OverlayItem>();

    DefaultResourceProxyImpl defaultResourceProxyImpl = new DefaultResourceProxyImpl(this);
    MyItemizedIconOverlay myItemizedIconOverlay = new MyItemizedIconOverlay(overlayItemArray, null, defaultResourceProxyImpl);
    mapView.getOverlays().add(myItemizedIconOverlay);
    //---

    locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

    //for demo, getLastKnownLocation from GPS only, not from NETWORK
    Location lastLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    if(lastLocation != null)
    {
        updateLoc(lastLocation);
    }

    //Add Scale Bar
    ScaleBarOverlay myScaleBarOverlay = new ScaleBarOverlay(this);
    mapView.getOverlays().add(myScaleBarOverlay);
}

@Override

{
    super.onResume();

private void updateLoc(Location loc)
{
    GeoPoint locGeoPoint = new GeoPoint(loc.getLatitude(), loc.getLongitude());
    mapController.setCenter(locGeoPoint);
    mapController.animateTo(locGeoPoint);

    setOverlayLoc(loc);

    mapView.invalidate();
}

private void setOverlayLoc(Location overlayloc)

    @Override

        if(!overlayItemArray.isEmpty())
        {
            //overlayItemArray have only ONE element only, so I hard code to get(0)
            GeoPoint in = overlayItemArray.get(0).getPoint();

            Point out = new Point();
            mapview.getProjection().toPixels(in, out);

            Bitmap bm = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher);
