我正在使用创建背景位置跟踪器Google FusedLocation API。在requestLocationUpdates()，我PendingIntent用于后台操作。当我运行我的应用程序时，前台位置跟踪器工作正常。但是，我的IntentService课似乎不起作用。我没有收到任何通知，后台没有任何反应。这就是我Google FusedLocation API在主片段类中实现的方式：

@Override
    public void onConnected(Bundle bundle) {

        .......

        //Starting Background Location Tracker
        if (mRequestingLocationUpdates)
        {
            createLocationRequest();
            startLocationUpdates();
        }
    }



protected void startLocationUpdates() {


        locationIntent = new Intent(getActivity().getApplicationContext(), LocationHandlerService.class);
        locationPendingIntent = PendingIntent.getService(getActivity().getApplicationContext(), 5,
                locationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


        LocationServices.FusedLocationApi.requestLocationUpdates(apiClient, locationRequest, locationPendingIntent);

    }

这是我的LocationHandlerService课：

public class LocationHandlerService extends IntentService {

    Location mLocation;
    NotificationManager notificationManager;

    public LocationHandlerService() {
        super("Services.LocationHandlerService");
    }


    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return START_STICKY;
    }

    @Override
    protected void onHandleIntent(Intent intent) {

        if (LocationResult.hasResult(intent)) {

            LocationResult locationResult = LocationResult.extractResult(intent);
            mLocation = locationResult.getLastLocation();

            if (mLocation != null) {
                setupNotification(mLocation);
            }
        }
    }

    //Setup Notification
    private void setupNotification(Location location) {

        notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.location_start_notification)
                .setOngoing(true)
                .setPriority(Notification.PRIORITY_HIGH)
                .setContentTitle(getResources().getString(R.string.location_notification))
                .setContentText("Lat: " + location.getLatitude() + ", Long: " + location.getLongitude());

        notificationManager.notify(0, notification.build());

    }

}

谁能告诉我的代码有什么问题？？？
