Solution 1:

There's a straightforward solution using the 2.0 Maps API. You'll get a nice smooth route line using three steps:

1. create a list of LatLng points such as:

   List<LatLng> routePoints;
   

2. Add the route points to the list (could/should be done in a loop):

   routePoints.add(mapPoint);
   

3. Create a Polyline and feed it the list of LatLng points as such:

   Polyline route = map.addPolyline(new PolylineOptions()
     .width(_strokeWidth)
     .color(_pathColor)
     .geodesic(true)
     .zIndex(z));
   route.setPoints(routePoints);
   

Give it a try!
