I think you need to refer to mapFieldDemo in order to understand how map works.
as i have read that i got to know that DemoMapField & MapFieldDemoScreen boh java file you need to look at closely which will be very useful to you to integrate map funtionality in your application.
As you want to locate your friend on your map i think
you need to override paint method in the DemoMapField.java file
in paint method you get all your longitude an latiude the convert each into XY point in order to put it on screen. then use this XY point and with the help of graphics you can use drawBitmap or drawText what ever you want.
