Answer 1

Try the modified codes for your onPostExecute:

@Override
protected void onPostExecute(List>> result) {
        ArrayList points = null;
        //PolylineOptions lineOptions = null;

        //MarkerOptions markerOptions = new MarkerOptions();

        points = new ArrayList();

        // Traversing through all the routes
        for(int i=0;i();
            //lineOptions = new PolylineOptions();              

            // Fetching i-th route
            List> path = result.get(i);

            // Fetching all the points in i-th route
            for(int j=0;j point = path.get(j);                 

                double lat = Double.parseDouble(point.get("lat"));
                double lng = Double.parseDouble(point.get("lng"));
                LatLng position = new LatLng(lat, lng); 

                points.add(position);                       
            }

            // Adding all the points in the route to LineOptions
            //lineOptions.addAll(points);
            //lineOptions.width(4);
            //lineOptions.color(Color.BLUE);

        }

        // Drawing polyline in the Google Map for the i-th route
        //map.addPolyline(lineOptions); 

        lineOptions.addAll(points);
        lineOptions.width(4);
        lineOptions.color(Color.BLUE); 
        line = map.addPolyline(lineOptions);
    }           

I moved your list points instance before for loop, and also lineOptions after for loop.

Hope this help.
