addGuidanceUpdatedListener
Adds a GuidanceUpdatedListener. The listener is notified of guidance updates, 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.
The listener is invoked on the main/UI thread.
Parameters
listener
The listener to be added.
