Пример за Osmdroid не работи

Искам да направя просто приложение за android с помощта на osmdroid, което просто трябва да показва карта. Включих и osmdroid-android-3.0.8.jar и slf4j-android-1.5.8.jar в проекта.

код:

package osmdemo.demo;

import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;

import android.app.Activity;
import android.os.Bundle;

public class Osm extends Activity {

private MapView         mMapView;
private MapController   mMapController;

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
           setContentView(R.layout.main);
       mMapView = (MapView) findViewById(R.id.mapview);
       mMapView.setTileSource(TileSourceFactory.MAPNIK);
       mMapView.setBuiltInZoomControls(true);
       mMapController = mMapView.getController();
       mMapController.setZoom(13);
       GeoPoint gPt = new GeoPoint(51500000, -150000);
       //Centre map near to Hyde Park Corner, London
       mMapController.setCenter(gPt);

   }
}

        ></org.osmdroid.views.MapView>
