CameraUpdateFactory.newLatLngZoom returns null

안녕하세요 저는 현재 학교 프로젝트를하고 있으며 버그가있는 곳을 잘 모릅니다. 내 코드가 잘못되었다고 생각하지 않습니다. 제발 도와주세요. 내 코드는 입니다. 이것은 제가 사용하는 모든 프로젝트입니다. 내가 된 CameraUpdate이CameraUpdateFactory.newLatLngZoom returns null

  googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(route.startLocation, 16)); 
    //((TextView) findViewById(R.id.textView2)).setText(route.duration.text); 
    //((TextView) findViewById(R.id.textView3)).setText(route.distance.text); 

    originMarkers.add(googleMap.addMarker(new MarkerOptions() 
      .icon(BitmapDescriptorFactory.fromResource(R.drawable.start_blue)) 
      .title(route.startAddress) 
      .position(route.startLocation))); 
    destinationMarkers.add(googleMap.addMarker(new MarkerOptions() 
      .icon(BitmapDescriptorFactory.fromResource(R.drawable.end_green)) 
      .title(route.endAddress) 
      .position(route.endLocation))); 

    PolylineOptions polylineOptions = new PolylineOptions(). 
      geodesic(true). 
      color(Color.BLUE). 
      width(10); 

    for (int i = 0; i < route.points.size(); i++) 
     polylineOptions.add(route.points.get(i)); 

    polylinePaths.add(googleMap.addPolyline(polylineOptions)); 

    routes.clear(); 
} 
}
