To invoke the maps from code you'll have to use the Invoke API.

Displaying a route can be achieved by using the MapsArguemnts

String doc = "<location-document>...</location-document>";
Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments(MapsArguments.ARG_LOCATION_DOCUMENT, doc));

Display and clear a route on a map by using a location document
