Android mapbox：如何取消注册IntentReceiver？

mapView = (MapView) findViewById(R.id.mapview);
    mapView.onCreate(savedInstanceState);

    mapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(MapboxMap mapboxMap) {
            my_function();
        }
    });

在my_function（）中我使用此订阅者：

GetDataSubscription = model.getData()
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe();

订阅开始时我有这个错误：
