Android API:
Mapbox Navigation SDK version: 0.16.0
navigation.startNavigation(route);MapMatching route is successfully passed to .startNavigation() and a turn-by-turn navigation session begins.
Crash:

I had the same problem , I've added these two lines :
.voiceUnits("metric")
.language("fr-FR")
in my matching.builder and it worked
MapboxMapMatching.builder()
.accessToken(Mapbox.getAccessToken())
.coordinates(liste)
.steps(true)
.bannerInstructions(true)
.roundaboutExits(true)
.voiceInstructions(true)
.voiceUnits("metric")
.language("fr-FR")
.profile(DirectionsCriteria.PROFILE_WALKING)
.build()
.enqueueCall(new Callback
Hope this help
