Привести KmlLayer к KmlPolygon

Question

На моем onMapReady() Я называю мой метод initKML() но есть проблема приведения KmlPolygon.

private void initKML() {
    try {
        KmlLayer kmlLayer = new KmlLayer(mMap, R.raw.kmlfile, getApplicationContext());
        kmlLayer.addLayerToMap();
        kmlLayer.setMap(mMap);
        moveCameraToKml(kmlLayer);
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

private void moveCameraToKml(KmlLayer kmlLayer) {
    KmlContainer container = kmlLayer.getContainers().iterator().next();
    KmlPlacemark placemark = container.getPlacemarks().iterator().next();
    KmlPolygon polygon = (KmlPolygon) placemark.getGeometry().getGeometryObject();
    LatLngBounds.Builder builder = new LatLngBounds.Builder();
    for (LatLng latLng : polygon.getOuterBoundaryCoordinates()) {
        builder.include(latLng);
    }

    int width = getResources().getDisplayMetrics().widthPixels;
    int height = getResources().getDisplayMetrics().heightPixels;
    mMap.moveCamera(CameraUpdateFactory.newLatLngBounds(builder.build(), width, height, 1));
}

И это мой файл KML
