body: <p>I installed correctly google map api on my app, all works fine with the emulator. But when i transfer it to my phone it doesn't work anymore (there is that grid thing), and i can't find what's wrong.</p>
  
  <pre><code>public class Main extends MapActivity {
      /** Called when the activity is first created. */
      MapView map ;
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
          map = (MapView)findViewById(R.id.mapview);
          map.setSatellite(true);
          List&lt;Overlay&gt; mapOverlays = map.getOverlays();
          Drawable drawable = this.getResources().getDrawable(R.drawable.pins);
          HelloItem itemizedoverlay = new HelloItem(drawable, this);
          GeoPoint point = new GeoPoint(19240000,-99120000);
          OverlayItem overlayitem = new OverlayItem(point, "Hola, Mundo!", "I'm in Mexico City!");
          itemizedoverlay.addOverlay(overlayitem);
          mapOverlays.add(itemizedoverlay);
          map.setBuiltInZoomControls(true);
      }
      @Override
      protected boolean isRouteDisplayed() {
          // TODO Auto-generated method stub
          return false;
