Как использовать Fuse android для определения местоположения в сервисе?

Я пытаюсь использовать Fuse провайдера в службе на Android, чтобы получить местоположение в фоновом режиме. 

  private void init() {
    context = this;
    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
    mSettingsClient = LocationServices.getSettingsClient(this);

    mLocationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            super.onLocationResult(locationResult);
            // location is received
            mCurrentLocation = locationResult.getLastLocation();
            mLastUpdateTime = DateFormat.getTimeInstance().format(new Date());

            showLocation();
        }
    };

    mRequestingLocationUpdates = false;

    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
    builder.addLocationRequest(mLocationRequest);
    mLocationSettingsRequest = builder.build();
}

   private void startLocationUpdates() {
    mSettingsClient
            .checkLocationSettings(mLocationSettingsRequest)
     =====>>>>       .addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
                @SuppressLint("MissingPermission")
                @Override
                public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
                    Log.i(TAG, "Started location updates!");
                    mFusedLocationClient.requestLocationUpdates(mLocationRequest, mLocationCallback, Looper.myLooper());

                     showLocation();
                }
            })
    =====>>>>        .addOnFailureListener(this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {

                }
            });
}

в службе я не могу использовать «это», потому что это относится к деятельности.

Я хочу знать, как реализовать этот код в сервисе?

Я изменил это, и работал ... 

    private void init() {
    context = this;
    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
    mSettingsClient = LocationServices.getSettingsClient(this);

    mLocationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            super.onLocationResult(locationResult);
            // location is received
            mCurrentLocation = locationResult.getLastLocation();
            mLastUpdateTime = DateFormat.getTimeInstance().format(new Date());

            showLocation();
        }
    };

    mRequestingLocationUpdates = false;

    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
    builder.addLocationRequest(mLocationRequest);
    mLocationSettingsRequest = builder.build();
    }



     private void startLocationUpdates() {
        mSettingsClient
                .checkLocationSettings(mLocationSettingsRequest)
         =====>>>>       .addOnSuccessListener(new OnSuccessListener<LocationSettingsResponse>() {
                    @SuppressLint("MissingPermission")
                    @Override
                    public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
                        Log.i(TAG, "Started location updates!");
                        mFusedLocationClient.requestLocationUpdates(mLocationRequest, mLocationCallback, Looper.myLooper());

                     showLocation();
                }
            })
    =====>>>>        .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {

                }
            });
}
...
