I am developing a tracking application, so I use GPS data to draw a route + waypoints on the canvas. The problem is that I developed scaling / dragging + dragging + span in SurfaceView and all the "long step to cartesian conversion", but it would be so easy to do all this if I could use the api map functionality (with my own overlay).
So my question is: can I use api / MapFragment maps without an internet connection and use the api functionality? Have any of you done something like this before?
