Mapbox-navigation-android: Mapbox mapmatching waypoint issue

[headbanggg]

Android API:27
Mapbox Navigation SDK version:com.mapbox.mapboxsdk:mapbox-android-navigation:0.16.0

Hello everyone,

I have a problem with banner instructions. In our app, we would like to start turn by turn navigation with a specific route that we provide from another service. So we use our route as input for mapbox mapmatching. We get response from mapmatching and pass it as directionRoute to navigationView.

Everything is great so far, I'm able to get mapmatched route and navigationView starts without problem.

Problem is banner instructions. Mapmatching API returns the route as waypoints. Navigation banner treat each waypoint as destination. So I'm getting "You have arrived" text continuously. In addition to this map is rotation when we arrive at a waypoint.
When I click on instruction banner It doesnt show the next steps.

It would be great if you can solve this issue.

Hi,

in your builder just add this line :
MapboxMapMatching.builder()
.accessToken(Mapbox.getAccessToken())
.coordinates(liste)
### .waypoints(0, liste.size()-1 )
.steps(true)
.bannerInstructions(true)
.roundaboutExits(true)
.voiceInstructions(true)
.voiceUnits("metric")
.language("fr-FR")
.profile(DirectionsCriteria.PROFILE_WALKING)
.build()

The liste variable contains the waypoints

That way, only the first and the last points will be the waypoints, the others will be there to track the route.

But beware,if you leave the route it will reroute you to the last point directly

hope this help

Hey @headbanggg 👋 Yeah it looks like the map matching response is returning a route completely made of waypoints, so the data / SDK is constantly providing arrival statuses.

Like @vincent-caron pointed out (thanks!), I'd work with the map matching request / adjust your parameters. Regarding map matching used with the NavigationView, please check out https://www.mapbox.com/android-docs/navigation/overview/map-matching/ as we have some guidelines on how to successfully reroute.

.waypoints(0, liste.size()-1 )

Thanks a lot for your help. It works like a charm 👍
