title: mapview and cameraupdate in api v2
body: <p>Why the CameraUpdateFactory class is not working in my project?
  The app crashes if it executes the following command:
               CameraUpdate pino= CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude())); 
  If i remove that line (and of course the next one), the code successfully starts and shows the map.
  I need the mapView and i need to use the new api v2.
  I declare the mapView in layout in this way:</p>
  
  <pre><code>        &lt;com.google.android.gms.maps.MapView
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:map="http://schemas.android.com/apk/res-auto"
  
      android:id="@+id/mappa"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_alignParentBottom="true"
      android:layout_below="@+id/buttonBar"
  
      map:uiZoomControls="false"
       /&gt;
  </code></pre>
  
  <p>then in mainActivity.java i wrote this:</p>
  
  <pre><code>    public class MainActivity extends FragmentActivity    implements LocationListener, LocationSource { 
  public static boolean locatingMe=true;
  public GoogleMap mappa;
  public MapView mapView;
  private OnLocationChangedListener onLocationChangedListener;
  private LocationManager locationManager;
  
  
  
  
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      mapView = (MapView) findViewById(R.id.mappa);
      mapView.onCreate(savedInstanceState);
  
  
          locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
  
      //You may want to pass a different provider in as the first arg here
      //depending on the location accuracy that you desire
      //see LocationManager.getBestProvider()
      Criteria locationCriteria = new Criteria();
      locationCriteria.setAccuracy(Criteria.NO_REQUIREMENT);
      locationManager.requestLocationUpdates(locationManager.getBestProvider(locationCriteria, true), 1L, 2F, this);
  
      if (mappa == null) {
          mappa=mapView.getMap();
          //This is how you register the LocationSource
          mappa.setLocationSource(this);
          mappa.getUiSettings().setMyLocationButtonEnabled(false);
          mappa.setMyLocationEnabled(true);
      }
  
  
  }
  @Override
  public void onPause()
  {
      if(locationManager != null)
      {
          locationManager.removeUpdates(this);
      }
      mapView.onPause();
      super.onPause();
  }
  
  @Override
  public void onResume()
  {
        checkGooglePlayServicesAvailability();
        checkGps();
        mapView.onResume();
        super.onResume();
  }
  @Override
  protected void onDestroy() {
      mapView.onDestroy();
      super.onDestroy();
  }
  
  @Override
  public void onLowMemory() {
      super.onLowMemory();
      mapView.onLowMemory();
  }
  
  @Override
  public void activate(OnLocationChangedListener listener) 
  {
      onLocationChangedListener = listener;
  }
  
  @Override
  public void deactivate() 
  {
      onLocationChangedListener = null;
  }
  
  @Override
  public void onLocationChanged(Location location) 
  {
      if( onLocationChangedListener != null )
      {
          onLocationChangedListener.onLocationChanged( location );
  
          //Move the camera to the user's location once it's available!
          //only if locatingMe is true
          if (locatingMe) {
              if (mappa!=null){
                  CameraUpdate pino= CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
                          mappa.animateCamera(pino);
  
              }
  
          }
  
      }
  }
  
  @Override
