Tracing user path on a MapView?

Hii Frnz,

I am developing an app which computes the distance travelled by the person and shows a map view which draws a line showing the user path from initial position to final position.

Now I am stuck as to how to trace a line on the user path...Should I try a custom annotations(or overlays) or is it possible to draw line on user path...a sample code would be very helpful if not possi开发者_JAVA技巧ble then please provide some suggestion as to how to proceed.
