Answer 1

Its Very Simple to draw the polyline as it Moves

Steps 1 : Create a polyline variable for references to update like below

private Polyline polyline_path;

Step 2 : On MapReady Callback do like below

PolylineOptions routes = new PolylineOptions().width(5).color(Color.BLUE);
    polyline_path = mMap.addPolyline(routes);

Step3 : On new Location you got call below method by sending points to this method

  private void UpdatePoints(LatLng newlatlng) {
    List points = polyline_path.getPoints();
    points.add(newlatlng);
    polyline_path.setPoints(points);
}
