Release Navigation SDK v3.21.0 · mapbox/mapbox-navigation-android

Navigation SDK Core Framework 3.21.0 - 02 April, 2026

GeoUtils: added getWayId overloads to retrieve OSM way id(s) by directed edge id or polyline span

Fixed an issue where the navigator would cycle between alternative routes after missing a turn at a waypoint, when the current position was already on the second leg of both the primary and alternative routes.
Fixed an issue in PredictiveCacheController that caused excessive resource consumption when the same map styles were requested for download multiple times.
Added geometryPointAt(index, precision) extension on RouteLeg that decodes leg geometry one step at a time and stops at the target index, avoiding allocation of all subsequent points.
Fixed an issue where requesting road cameras using RoadCamerasProvider could potential stall the main thread.
Fix redundant leg geometry decoding in SlowTrafficSegmentsFinder by caching decoded points per route instance, and eliminate iterator allocations in congestion range lookup.
Added a minimum speed threshold for applying avoid-maneuver-radius for continuou alternative route, so that Nav SDK can suggest alternatives with maneuver being close in case of low speed.
Improved off-road mode detection in parking aisles that are marked as tunnels.
Improved ADAS cache performance.
Fixed a crash that could occur after navigation shutdown.
Improved performance on routes with a large number of road alerts.

This release depends on, and has been tested with, the following Mapbox dependencies:
