                       throws java.lang.IllegalArgumentException

Set the navigation params, and the listener that receives the updated navigation progress.

Can only exist one navigation with one listener at a time. If this method was previously invoked, but removeUpdates() wasn't, removeUpdates() is called internally.

Parameters:

listener - NavigationListener that receives updates of navigation progress.

Throws:

java.lang.IllegalArgumentException - if listener, request or NavigationRequest.route are null, or if NavigationRequest.distanceToGoalThreshold or NavigationRequest.outsideRouteThreshold have 0 or negative value.

Parameters:

location - new Location of the user. If null, nothing is done

Returns:

true if there is a listener to which notify progress update. False if there isn't, so this method do nothing.

removeUpdates

boolean removeUpdates()

Returns:

true if a listener was removed. False if there was no listener.

isRunning

boolean isRunning()

Returns true if the navigation is running, false otherwise
