This component integrates the Routing API described on https://developer.tomtom.com/routing-api/routing-api-documentation. The service calculates a route between an origin and a destination, passing through waypoints if they are specified.

The outing API is one of our most advanced APIs, enabling the user to calculate a perfect path from point A to point B.

RoutingBuilder is instantiated with the API Key for the TomTom Online Routing service.
You can set an origin and a destination, if you want to route from the current location, then simply pass it to the from() method of the RoutingBuilder.
You can set a list of via points to lead the way though them.
You can provide locations as points, or as approximate points (circles).

To initialise routing:

_

routePlannerAPI = OnlineRoutingApi.create(context);

private val routingApi = OnlineRoutingApi.create(context)!!

To execute routing:

_

Disposable subscribe = routePlannerAPI.planRoute(routeQuery).subscribeOn(getWorkingScheduler())
        .observeOn(getResultScheduler())
        .subscribe(routeResult -> displayRoutes(routeResult, routeStyle, startIcon, endIcon),
                throwable -> proceedWithError(throwable.getMessage()));
Disposable subscribe = routePlannerAPI.planRoute(routeQuery).subscribeOn(getWorkingScheduler())
        .observeOn(getResultScheduler())
        .subscribe(
                routeResult -> displayRoutes(routeResult),
                throwable -> proceedWithError(throwable.getMessage()));

disposable.set(routingApi.planRoute(routeQuery)
        .subscribeOn(workingScheduler)
        .observeOn(resultScheduler)
        .subscribe(
                { response -> result.value = Resource.success(response.routes) },
                { error -> result.value = Resource.error(null, Error(error.message)) }
        )
)

To display a route on the map:

_

RouteBuilder routeBuilder = new RouteBuilder(route.getCoordinates())
        .endIcon(endIcon)
        .startIcon(startIcon)
        .style(routeStyle);
final Route mapRoute = tomtomMap.addRoute(routeBuilder);

val routeBuilder = RouteBuilder(route.coordinates)
        .style(RouteStyle.DEFAULT_ROUTE_STYLE)
        .startIcon(createIcon(R.drawable.ic_map_route_origin))
        .endIcon(createIcon(R.drawable.ic_map_route_destination))
        .tag(routeIdx.toString())
tomtomMap.addRoute(routeBuilder)
