更快的路线检测和替代路线未在地图框中显示

Question

我已经尝试在我的项目中实现更快的路由检测和替代路由。但是我从文档中尝试的代码似乎无法正常工作。在这里，我将提供代码以更好地理解。

MapboxNavigationOptions mapOptions = MapboxNavigationOptions.builder()
                    .build();
mapOptions.enableFasterRouteDetection();
mapboxNavigation = new MapboxNavigation(MapBoxActivity.this, Mapbox.getAccessToken(), mapOptions);
mapboxNavigation.addFasterRouteListener(new FasterRouteListener() {
        @Override
        public void fasterRouteFound(DirectionsRoute directionsRoute) {
            // Update MapboxNavigation here
            // navigation.startNavigation(directionsRoute);
            mapboxNavigation.startNavigation(directionsRoute);
        }
  });

NavigationRoute.builder(this)
            .accessToken(Mapbox.getAccessToken())
            .origin(origin)
            .alternatives(true)
            .destination(destination)
            .build()
            .getRoute(new Callback<DirectionsResponse>() {
                @Override
                public void onResponse(Call<DirectionsResponse> call, Response<DirectionsResponse> response) {
                    // You can get the generic HTTP info about the response
                    Log.d(TAG, "Response code: " + response.code());
                    if (response.body() == null) {
                        Log.e(TAG, "No routes found, make sure you set the right user and access token.");
                        Toast.makeText(MapBoxActivity.this, "No routes found, make sure you set the right user and access token.", Toast.LENGTH_SHORT).show();
                        return;
                    } else if (response.body().routes().size() < 1) {
                        Log.e(TAG, "No routes found");
                        Toast.makeText(MapBoxActivity.this, "No routes found.", Toast.LENGTH_SHORT).show();
                        return;
                    }

                    currentRoute = response.body().routes().get(0);

                    // Draw the route on the map
                    if (navigationMapRoute != null) {
                        navigationMapRoute.removeRoute();
                    } else {
                        navigationMapRoute = new NavigationMapRoute(null, mapView, mapboxMap, R.style.NavigationMapRoute);
                    }

                    navigationMapRoute.addRoute(currentRoute);

                }

                @Override
                public void onFailure(Call<DirectionsResponse> call, Throwable throwable) {
                    Log.e(TAG, "Error: " + throwable.getMessage());
                }
            });

请有人指出我犯了什么错误。预先感谢您的帮助。
