how to get total distance and duration between two location along with waypoint in google map

Question

i want to get total duration and distance between two location along with waypoints. the methodwhich i'm using is giving me distance and duration but without waypoints. so can any one help me? my method look like below...

public String getDistance(final double lat1, final double lon1, final double lat2, final double lon2){


Thread thread=new Thread(new Runnable() {
@Override
public void run() {
try {
URL url = new URL("https://maps.googleapis.com/maps/api/directions/json?origin=" + lat1 + "," + lon1 + "&destination=" + lat2 + "," + lon2 + "&sensor=false&units=metric&mode=driving&key="+getResources().getString(R.string.google_maps_server_key));
final HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
InputStream in = new BufferedInputStream(conn.getInputStream());
response = org.apache.commons.io.IOUtils.toString(in, "UTF-8");

JSONObject jsonObject = new JSONObject(response);
JSONArray array = jsonObject.getJSONArray("routes");
JSONObject routes = array.getJSONObject(0);
JSONArray legs = routes.getJSONArray("legs");
JSONObject steps = legs.getJSONObject(0);
JSONObject distance = steps.getJSONObject("distance");
parsedDistance=distance.getString("text");
JSONObject duration= steps.getJSONObject("duration");
parsedDuration=duration.getString("text");
} catch (IOException | JSONException e) {
e.printStackTrace();
}
}
});

thread.start();

try {
thread.join();
Toast.makeText(this, parsedDistance + " Distance", Toast.LENGTH_SHORT).show();
Toast.makeText(this, parsedDuration + " Duration", Toast.LENGTH_SHORT).show();
} catch (InterruptedException e) {
e.printStackTrace();
}

return parsedDistance;
}

public void parseJson(JSONObject jObject) {

        List<List<HashMap<String, String>>> routes = new ArrayList<>();
        JSONArray jRoutes;
        JSONArray jLegs;
        JSONArray jSteps;
        JSONObject jDistance = null;
        JSONObject jDuration = null;
        long totalDistance = 0;
        int totalSeconds = 0;

        try {

            jRoutes = jObject.getJSONArray("routes");

            /* Traversing all routes */
            for (int i = 0; i < jRoutes.length(); i++) {
                jLegs = ((JSONObject) jRoutes.get(i)).getJSONArray("legs");

                                /* Traversing all legs */
                for (int j = 0; j < jLegs.length(); j++) {

                    jDistance = ((JSONObject) jLegs.get(j)).getJSONObject("distance");

                    totalDistance = totalDistance + Long.parseLong(jDistance.getString("value"));

                    /** Getting duration from the json data */
                    jDuration = ((JSONObject) jLegs.get(j)).getJSONObject("duration");
                    totalSeconds = totalSeconds + Integer.parseInt(jDuration.getString("value"));

                }
            }

            double dist = totalDistance / 1000.0;
            Log.d("distance", "Calculated distance:" + dist);

            int days = totalSeconds / 86400;
            int hours = (totalSeconds - days * 86400) / 3600;
            int minutes = (totalSeconds - days * 86400 - hours * 3600) / 60;
            int seconds = totalSeconds - days * 86400 - hours * 3600 - minutes * 60;
            Log.d("duration", days + " days " + hours + " hours " + minutes + " mins" + seconds + " seconds");

        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

JSONObject jObject = new JSONObject(result);

parseJson(jObject);
