How to recalculate the route when exiting it in Mapbox Android?

Question

I would like to know how to recalculate the route in the Android mapbox, since leaving the route continues the same initially mapped. For dash the route, start the navigation and even left it both the navigation and the route are not recalculated. I thank everyone.

public void getRoute(List<Point> waypoints){

    waypointSize = waypoints.size();
    Log.d("tag", "WaypointSSize: "+waypoints.size());
    // Transforma localizacao atual em Point para o MapBox
    Point origin = Point.fromLngLat(currentLocation.getLongitude(),currentLocation.getLatitude());
    Log.d("tag", "Origin: "+origin);
    for (Point destination : waypoints){
        // Criando a rota -> Token tem que ser AccessToken
        NavigationRoute.Builder builder = NavigationRoute.builder(this)
                .accessToken("sk.eyJ1IjoiYWhlbnRyZWdhIiwiYSI6ImNqc2NkZ2ptZjAwYmEzenA2Zmo0MDBoNjQifQ.0r13_lXZMCNdaWrkYddRLg")
                .origin(origin)
                .destination(destination);

        builder.build().getRoute(new Callback<DirectionsResponse>() {
            @Override
            public void onResponse(Call<DirectionsResponse> call, Response<DirectionsResponse> response) {
                Log.d("tag", ""+response.code());
                // Verificando se a problema como o AccessToken
                if (response.body() == null){
                    Log.d("tag","Nenhuma rota encontrada, check access token");
                    return;
                    // Verificando se nao foi encontrada nenhuma rota
                }else if(response.body().routes().size() < 1){
                    Log.d("tag","Nenhuma rota encontrada");
                    return;
                }
                // Adicionando a rota a variavel do MapBox
                currentRoute = response.body().routes().get(0);

                if (distancia == 0){
                    distancia = currentRoute.distance();
                    route = currentRoute;
                }else if (distancia > currentRoute.distance()){
                    distancia = currentRoute.distance();
                    route = currentRoute;
                }
                cont++;
                if (cont == waypointSize){
                    // Verificando se ja existe uma rota no mapa
                    if (navigationMapRoute != null) {
                        navigationMapRoute.removeRoute();
                    } else {
                        navigationMapRoute = new NavigationMapRoute(null, mapView, map);
                    }
                    // Adicionando a rota no mapa
                    navigationMapRoute.addRoute(route);

                    navigation.startNavigation(route);

                    // LatLng para marcar no mapa o destino
                    LatLng latLng = new LatLng(destination.latitude(),destination.longitude());
                    map.addMarker(new MarkerOptions().setPosition(latLng));
                }

                Log.d("tag", ""+currentRoute.distance());
                Log.d("tag", ""+currentRoute.duration());
            }

            @Override
            public void onFailure(Call<DirectionsResponse> call, Throwable t) {
                Log.d("Rota",t.getMessage());
            }
        });
    }
    Log.d("Rota", "WaypointSSize: "+waypoints.size());


}

The Navigation SDK includes an OffRouteListener that is not enabled by default.

The documentation goes into detail about how to detect when a user is off the initial route and trigger a request for a new route: https://docs.mapbox.com/android/navigation/overview/off-route/
