title: Android GoogleMaps V2 doesnt refresh
body: <p>My App displays the driven route of the user. After a few seconds, the map stops loading new content and looks like this:

  <p>My Code:
  XML</p>
  
  <pre><code>    &lt;fragment 
      xmlns:android="http://schemas.android.com/apk/res/android"
      class="com.google.android.gms.maps.SupportMapFragment"
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      map:cameraZoom="19"
      android:layout_below="@+id/tracking_maps_colorgradient"&gt;
  &lt;/fragment&gt;
  </code></pre>
  
  <p>Java:</p>
  
  <pre><code>            float zoom =  18;//googleMap.getCameraPosition().zoom;
          LatLng latLng = new LatLng(lastLatitude, lastLongitude);
          locations.add(latLng);
          CameraPosition pos = new CameraPosition.Builder()
              .target(latLng)
              .bearing(bearing)
              .zoom(zoom)
              .tilt(googleMap.getCameraPosition().tilt)
              .build();
  
          googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(pos));
          Polyline p = googleMap.addPolyline(new PolylineOptions()
              .add(latLng)
              .width(15)
              .color(Color.RED)
              .geodesic(true));
          p.setPoints(locations);
  </code></pre>
  
  <p>Is there a way to invalidate the Map? </p>
  
  <p>Thanks for your help!</p>
