Android Google map Excepción de puntero nulo al agregar marcador

He hecho una simple FragmentActivity mostrar el mapa de google y el uso de marcadores para mostrar la posición actual y lugares cercanos. Pero ahora necesito usar ese código dentro de otra aplicación, y estoy recibiendo este problema.

Esta es la actividad

private void updatePlaces(JSONArray jDestinationArray) throws JSONException{ locMan = (LocationManager)getSystemService(Context.LOCATION_SERVICE); Location lastLoc = locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); double lat = lastLoc.getLatitude(); double lng = lastLoc.getLongitude(); lastLatLng = new LatLng(lat, lng); Display display = getWindowManager().getDefaultDisplay(); Point size = new Point(); display.getSize(size); int width = size.x; int height = size.y; Builder boundsBuilder = new LatLngBounds.Builder(); boundsBuilder.include(lastLatLng); markers = new HashMap<Marker,Object>(); userMarker = map.addMarker(new MarkerOptions() .position(lastLatLng) .title("You are here") .icon(BitmapDescriptorFactory.fromResource(userIcon)) .snippet("This is your last recorded location")); markers.put(userMarker, lastLatLng); for(int i=0; i<jDestinationArray.length(); i++){ JSONObject destinationObject = jDestinationArray.getJSONObject(i); LatLng latlng = new LatLng(destinationObject.getDouble("latitude"), destinationObject.getDouble("longitude")); Marker destinationMarker= map.addMarker(new MarkerOptions() .position(latlng) .title(destinationObject.getString("name")) .icon(BitmapDescriptorFactory.fromResource(destinationIcon)) .snippet(destinationObject.getString("street")) ); markers.put(destinationMarker, latlng); boundsBuilder.include(latlng); } // pan to see all markers on map: LatLngBounds bounds = boundsBuilder.build(); map.moveCamera(CameraUpdateFactory.newLatLngBounds(bounds, width, height, 30)); //map.animateCamera(CameraUpdateFactory.newLatLng(lastLatLng), 3000, null); }

Y el registro, cuando abro el mapa:

No veo donde usted asigna userIcon cualquier valor, y por BitmapDescriptorFactory.fromResource(userIcon) tanto BitmapDescriptorFactory.fromResource(userIcon) puede estar devolviendo null como resultado.

Primero verifique que google map es null o notnull usando este método -> If (gMap! = Null)
Si usted tiene que descargar el icono del marcador url del formulario (o) añadir la imagen del marcador a la ventana de información del marcador directamente desde el url.its posible obtener la excepción de hilo principal de la red.
La excepción de hilo principal de red conduce a la imagen de marcador null para que pueda obtener una excepción de puntero nulo en google map

Solución:

Agregue las siguientes líneas en su método onCreate

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder (). AllowAll (). Build ();

StrictMode.setThreadPolicy (policy);
