Using multi-stop navigation

Multi-stop navigation has been introduced with the release of 4.8.0. This allows users to be navigated to multiple stops within a single route.

Querying a multi-stop route

To query a multistop route a new overload MPDirectionsService.query has been introduced MPDirectionsService.query(from: MPPoint, to: MPPoint, stops: List<MPPoint>?, optimize: Boolean).

private var directionsService: MPDirectionsService = MPDirectionsService()

//Example of querying an optimized route with multiple stops
fun getRoute() {
    if (directionsService != null) {
        directionsService = MPDirectionsService()
    //Setting listener to receive the queried route
    directionsService.setRouteResultListener { route, error ->
        if (error == null && route != null) {
            //Route is received
        } else {
            Log.i("Directions", "Error: $error")
    //Creating variables to use for the query
    val origin = MPPoint(57.05800975, 9.949916517)
    val destination = MPPoint(57.058278, 9.9512196, 10.0)
    val stops = listOf(MPPoint(57.0582701, 9.9508396, 0.0), MPPoint(57.0580431, 9.9505475, 0.0), MPPoint(57.0580843, 9.9506085, 10.0))
    directionsService.query(origin, destination, stops, true)

Showing and configuring a multi-stop route on the map

With the introduction of the multi-stop routes. There has also been added new functionality to the MPDirectionsRenderer to facilitate the new multi-stop routes.

You can still render the route as a Route with stops, using setRoute(route: MPRoute) on the DirectionsRenderer. But the interface of the MPDirectionsRenderer has been expanded with a defaultStopIcon as well as an overload of: setRoute(route: MPRoute, icons: HashMap<Integer, MPRouteStopIconProvider>?)

The defaultStopIcon can be configured to show any image. It can also be set to null, to not show any icon for the stops on the Route. We supply the MPRouteStopIconConfig that allows you to customize the default pin to fit your application.

//Changing the default icon to be blue, with a Meeting Room label and with no number inside the pin
val defaultRouteStopIcon = MPRouteStopIconConfig.Builder(myContext)
                                .setLabel("Meeting Room")

To use your own images, you can extend the MPRouteStopIconProvider with your own class. Here is an example using a bitmap for the image

class BitmapRouteStopIcon(val image: Bitmap) : MPRouteStopIconProvider() {
    override fun getImage(): Bitmap? {
        return image

Adding a custom image to a specific waypoint

It is also possible to render an image specific to a single stop. By using setRoute(route: MPRoute, icons: HashMap<Integer, MPRouteStopIconProvider>?)

val stopIcons = mapOf(2 to MPRouteStopIconConfig.Builder(this).setColor(Color.BLUE).build())
directionsRenderer?.setRoute(route, HashMap(stopIcons))

Here we will show a blue icon for the third stop. Leaving the first two indexes as null, means that the renderer will use the defaultStopIcon. If you want to render a specific known stop on an optimized route. You can find the ordering of the stops on an optimized route through MPRoute.orderedStopIndexes.
