Выполнение внутреннего вызова API из службы

Question

У меня есть служба, которая работает как на переднем, так и на заднем плане, чтобы постоянно определять местоположение пользователя, я просто использую LocalBroadCastManager, чтобы отправить местоположение с переднего плана на активность в моем приложении, а затем запустить мой вызов API.

Как добиться того же, когда служба работает в фоновом режиме или когда приложение закрыто.

Служба:

public class LocationService extends Service {

    private static final String TAG = "LocationService";
    private LocationManager mLocationManager = null;
    private static final int LOCATION_INTERVAL = 0;
    private static final float LOCATION_DISTANCE = 1000f;
    private HandlerThread mHandlerThread;
    private Handler mHandler;
    private final IBinder mBinder = new MyLocalBinder();
    Location mLastLocation;

    private class LocationListener implements android.location.LocationListener
    {


        public LocationListener(String provider)
        {
            Helper.showLog(TAG, "LocationListener " + provider);
            mLastLocation = new Location(provider);

        }

        @Override
        public void onLocationChanged(Location location)
        {
            Helper.showLog(TAG, "onLocationChanged: " + location);
            mLastLocation.set(location);
            sendBroadcast();
        }

        @Override
        public void onProviderDisabled(String provider)
        {
            Helper.showLog(TAG, "onProviderDisabled: " + provider);
        }

        @Override
        public void onProviderEnabled(String provider)
        {
            Helper.showLog(TAG, "onProviderEnabled: " + provider);
        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras)
        {
            Helper.showLog(TAG, "onStatusChanged: " + provider);
        }
    }

    LocationListener[] mLocationListeners = new LocationListener[] {
            new LocationListener(LocationManager.GPS_PROVIDER),
            new LocationListener(LocationManager.NETWORK_PROVIDER)
    };

        mHandlerThread.start();
        mHandler = new Handler(mHandlerThread.getLooper());
        initializeLocationManager();
        try {

            mLocationManager.requestLocationUpdates(
                    LocationManager.GPS_PROVIDER, LOCATION_INTERVAL, LOCATION_DISTANCE,

    }

 private void sendBroadcast(){

     intent.putExtra("latitude",mLastLocation.getLatitude() );

 LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
