  OK just a line from point A to point B then.

  This is (not yet) possible with the builed in maps application. What you can do is create a webview, make a page with the google maps api, and do your location handeling in that. The code for drawing lines in the google maps API is this:

  var polyline = new GPolyline([
    new GLatLng(37.4419, -122.1419), //lat/lon point1
    new GLatLng(37.4519, -122.1519) // lat/lon point 2
  ], "#ff0000", 10); // line color, line width
  
  map.addOverlay(polyline);
  

• If you mean like drawing a line from point a to b through the streets on a map, that is only possible in the official maps app.

• no, i dont want to add point on streets, but outside, like on a hiking trail.
