            // // Move the camera instantly to hamburg with a zoom of 15.
            map.moveCamera(CameraUpdateFactory.newLatLngZoom(point, 14));
            map.animateCamera(CameraUpdateFactory.zoomTo(14), 2000, null);
        } catch (Exception e) {
        }

    }
}

@Override
public void RealTimeLocation(int memberId, final double lat, final double lng) {
    // TODO Auto-generated method stub
    runOnUiThread(new Runnable() {
        public void run() {

            Latreccvier = String.valueOf(lat);
            Lonreccvier = String.valueOf(lng);

            LatLng point1=new LatLng(Double.parseDouble(Latreccvier), Double.parseDouble(Lonreccvier));
            friendMarker.setPosition(point1);
        }
    });
}

this is my code i want to draw ply line on google map i am able to move marker at same time i want to draw path of line of moving google map.

public void RealTimeLocation(int memberId, final double lat, final double lng) { 
a

using this method i am getting 4 to 5 lat long on Location changed i am trying to add freindlatlong.add(point1); where freindlatlong is array list according to that i try to add Plyline but not work please suggest me how to draw path line on map.

        }

    }

Try this ,very good code for drawing poly-line:

 MarkerOptions markerOptions = new MarkerOptions();

            // Setting latitude and longitude of the marker position
            markerOptions.position(point);

            // Setting titile of the infowindow of the marker
            markerOptions.title("Position");

            // Setting the content of the infowindow of the marker
            markerOptions.snippet("Latitude:"+point.latitude+","+"Longitude:"+point.longitude);

            // Instantiating the class PolylineOptions to plot polyline in the map
            PolylineOptions polylineOptions = new PolylineOptions();

            // Setting the color of the polyline
            polylineOptions.color(Color.RED);

            // Setting the width of the polyline
            polylineOptions.width(3);

            // Adding the taped point to the ArrayList
            points.add(point);

            // Setting points of polyline
            polylineOptions.addAll(points);

            // Adding the polyline to the map
            googleMap.addPolyline(polylineOptions);

            // Adding the marker to the map
            googleMap.addMarker(markerOptions);
