title: marker in the osm Map with osmdroid
body: <p>I am trying to display a marquer in OSM, but can't. I can display the OSM map and the location of my phone, but nothing else. </p>
  
  <p>Here is my code:</p>
  
  <pre><code>public class Carte2Activity extends Activity implements LocationListener {
      MapView mapView;
      MapController myMapController;
      MyLocationOverlay location = null;
      double lat;
      double lng;
      LocationManager lm;
      LocationListener ll;
  
      ArrayList&lt;OverlayItem&gt; anotherOverlayItemArray;
      String[] sources;
  
      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main); 
          mapView = (MapView)findViewById(R.id.openmapview);
          mapView.setBuiltInZoomControls(true);
          mapView.setMultiTouchControls(true);
  
          lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
          ll = new Myll();
          lm.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,ll);
  
          myMapController = mapView.getController();
          myMapController.setZoom(10);
          myMapController.setCenter(new GeoPoint((int)(48.785152*1E6), (int)(2.285156*1E6)));
  
  
          location = new MyLocationOverlay(getApplicationContext(), mapView);
  
         //ajouter la loc
          mapView.getOverlays().add(location);
          //afficher
          location.enableMyLocation();
  
      }      
  
      private class Myll implements LocationListener{
  
      public void onLocationChanged(Location location) {
          // TODO Auto-generated method stub
          lat = location.getLatitude();
          lng = location.getLongitude();
          run();
      }
  
      public void run() {
          // TODO Auto-generated method stub
          location.runOnFirstFix(new Runnable() { public void run() {
              mapView.getController().animateTo(location.getMyLocation());
              }}); 
      }
  
      public void onProviderDisabled(String provider) {
          // TODO Auto-generated method stub      
      }
  
      public void onProviderEnabled(String provider) {
          // TODO Auto-generated method stub      
      }
  
      public void onStatusChanged(String provider, int status, Bundle extras) {
          // TODO Auto-generated method stub      
      }
  }
  
      public void onLocationChanged(Location location) {
          // TODO Auto-generated method stub      
      }
