@Override
public void onCameraChange(CameraPosition arg0) {
    // camera's center
    LatLng a = arg0.target;
    double lat = a.latitude;
    double lng = a.longitude;
    // you can also access the field-of-view
    LatLngBounds boundingBox = mMap.getProjection().getVisibleRegion().latLngBounds;
