I was wondering how to load an already created kml file into the mapview programatically? The kml file is stored in the SDcard. I have a mapActivity already set up. Do I just SAX parse the kml file and use the draw method to create the boundary? Here is a snippet of the kml file stored on the phone

I am a student and am new to android so any help be greatly appreciated Thanks
You could parse the KML file using something like a SAXParser and get the coordinates for your way-points.
Then, you could draw them on the MapActivity: Link
