Apps GPS Location Distance

[Ravi Pratap Singh]

How we find exact distance b/w two point on gmap in android ?
I am using this

public String getDistance(final double lat1, final double lon1, final double lat2, final double lon2){
    String parsedDistance;
    String response;
    Thread thread=new Thread(new Runnable() {
        [USER=1021285]@override[/USER]
        public void run() {
            try {

                URL url = new URL("http://maps.googleapis.com/maps/api/directions/json?origin=" + lat1 + "," + lon1 + "&destination=" + lat2 + "," + lon2 + "&sensor=false&units=metric&mode=driving");
                final HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setRequestMethod("POST");
                InputStream in = new BufferedInputStream(conn.getInputStream());
              String  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");
              String  parsedDistance=distance.getString("text");

            } catch (ProtocolException e) {
                e.printStackTrace();
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    });
    thread.start();
    try {
        thread.join();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    return parsedDistance;
}

but error is comming in this line
String response = org.apache.commons.io.IOUtils.toString(in, "UTF-8");

What's the error? If the application crashed, please include the stack trace from the Logcat view.

Be careful dabbling in those type of programs you're going to raise some unwanted suspicions.
