addGuidanceUpdatedListener
Adds a GuidanceUpdatedListener. The listener is notified of new Guidance instances, whenever there is a change in location and the GuidanceEngine successfully generates it.
Important: To ensure that GuidanceUpdatedListener is triggered, be sure you include GuidanceOptions in RoutePlanningOptions during route planning. Otherwise, the route will lack guidance information, and the listener will not be activated.
Parameters
listener
The listener to be added.
