    //Depends on the use case, you can hold directionClient on your fragment or activity or applicaiton
private val directionClient: DirectionClient = DirectionClient.Factory.hybridClient()

    RouteRequest request = (new RouteRequest.Builder(
        new GeoLocation(37.405022D, -122.061887D),
        new GeoLocation(37.39962D, -121.977785D)))
        .contentLevel(ContentLevel.FULL)
        .routeCount(2)
        .build();

            ).contentLevel(ContentLevel.FULL)
            .routeCount(2)
            .build()

    Task<RouteResponse> task = directionClient.createRoutingTask(request);
task.runAsync(response -> {

        if (response.getResponse().getStatus() == DirectionErrorCode.OK) {
            Log.i(
                    "SecondFragment. routing",
                    "route request success! routes: " + response.getResponse().getResult().size()
            );

            Route route = response.getResponse().getResult().get(0);
            //  TODO present the route on map or start navigation with the route
            //  ...
        } else {
            Log.e("route requesting", "routing failed");
        }
    }
