Navigation SDK Core Framework 3.18.0 - 16 January, 2026

Features

• Added Experimental API:
  • MapboxNavigation#registerVoiceInstructionsAvailableObserver and MapboxNavigation#unregisterVoiceInstructionsAvailableObserver to be notified when voice instructions become available or unavailable;
  • MapboxNavigation#registerRelevantVoiceInstructionsCallback to asynchronously fetch the relevant voice instructions. The callback is automatically unregistered after receiving the result, register again for subsequent voice instructions.
• Adjust FollowingFrameOptions#maxZoom: The value is applied directly when the zoom level cannot be calculated precisely, e.g., when there is only one point to frame.
• Added experimental NavigationOptions#nativeRouteObject which replaces NavigationRoute#directionsRoute with a thin wrapper that accesses route data stored in native memory instead of the Java heap. This is an early preview feature. When this option is enabled, some functionality is disabled or not fully supported. See NavigationOptions#nativeRouteObject for details.
• Added new class RerouteStateV2: it allows you to observe RerouteStates with additional substates which are not present in the original RerouteState.
  Current additional states are: RerouteStateV2.Deviation.ApplyingRoute and RerouteStateV2.Deviation.RouteIgnored. See the corresponding API reference for details. To observe RerouteStateV2, register a new type of observer: RerouteController#registerRerouteStateV2Observer.
• Capabilities list added to Connector object, so it is now compliant with OCPI v2.3.0
• Added an isOffline flag to EvStationMarker to identify when charging station data is from an offline source.
• Added support of connctor types in MapboxEvViewOptions to be able to customize the connector types in the EV view.

Bug fixes and improvements

• Made RerouteStateV2 a sealed class.
• Fixed an issue when adding a stop point on top of an already traversed route, which could show a carried-over vanishing portion from the previous route. That is accomplished by ensuring that MapboxRouteLineApi.getVanishPointOffset() returns 0.0 in case the point was in the VanishingPointState.DISABLED state.
• Obfuscated access token in RouteShieldError#url#toString.
• Improved EV SAR call to return requested number of charging stations.
• Fix an issue where transitionEndListener passed to NavigationCamera#requestNavigationCameraTo... might not have been invoked.
• Added RouterFailureType.ROUTER_RECREATION_ERROR when route request failed due to related reason and made this error retriable
• Improved EV SAR call to evenly distribute returned stations along the route.
• Fixed the routing tiles endpoint configuration to avoid redundant recreations of Navigator.
• ⚠️ Breaking change (preview API): removed MapboxRoadCamerasDisplayConfig::showOnlyOnRoute. Safe to remove. It's now a default behavior to show road cameras only on the route.
• Fixed a bug that prevented road cameras from being removed from the map after passing them.
• Fixed an issue when re-route might take a few minutes, because of missing internal reroute state.
• Fixed Copilot issues that caused recordings to be lost.
• Fix ConcurrentModificationException in RoadCamerasByTileProvider
• Fix the race condition when canceling Active Guidance from a background thread that does not immediately cancel Route Progress updates.
• Avoid high CPU usage when user location is stationary.
• Improve DR accuracy after sharp turns.
• Update interface for retrieving last voice instructions.
• Incident positions after a mid-leg route refresh now use correct distance calculations.
• Disallow route refreshes in other than Tracking state.
• Native Route Object via Flatbuffers.
• Implement reaction on notification that user-provided-charging-station is not needed.
