GeoPoint is only for Maps V1. To draw lines in Maps V2, you would add a Polyline to your GoogleMap :

  PolylineOptions line=
      new PolylineOptions().add(new LatLng(40.70686417491799,
                                           -74.01572942733765),
                                new LatLng(40.76866299974387,
                                           -73.98268461227417),
                                new LatLng(40.765136435316755,
                                           -73.97989511489868),
                                new LatLng(40.748963847316034,
                                           -73.96807193756104))
                           .width(5).color(Color.RED);

  map.addPolyline(line);
