J2ME/Android/BlackBerry - driving directions, route between two locations

I'm just writing an App for displaying the route between two coords (lat, long) in google maps view. Displaying an single coord (even with a marker) works fine, but how to draw route between two point with 2 markers?

I must admit that I'm quite new to Android and the maps-API...

  • I am doing a similar kind of app and like to know if using kml or using the api to return a json is better.

  • One note, you might be running afoul of the Google Maps api if you use it to obtain driving directions (they removed this capability from the android maps api).

  • yep. but we can do manipulations with the kml file of maps. in my answer, they are retriving the coordinates points to the route from the google maps kml file. check the RoadProvider.java the are build the url to get the road coordintes from the kml file.

Your route will be a list of points so you have to create a route overlay class. And in the draw method of the overlay class you have to draw a Path between the points.
