Http Post Request in Android

public class HttpHelper extends AsyncTask < Void, Void, String >
{
    private String url = "SOME_POST_URL";
    @Override
    protected String doInBackground(Void...params)
    {
        String resultString = null;
        JSONObject json = new JSONObject();
        try
        {
            json.put("email", "EMAIL");
            json.put("password", "PASSWORD");
        }
        catch (JSONException e)
        {}
        DefaultHttpClient client = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        ByteArrayEntity arrayEntity = new ByteArrayEntity(json.toString().getBytes());
        httpPost.setEntity(arrayEntity);
        httpPost.setHeader("Accept", "application/json");
        httpPost.setHeader("Content-type", "application/json");
        HttpResponse httpResponse;
        try
        {
            httpResponse = client.execute(httpPost);
            InputStream stream = httpResponse.getEntity().getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(stream));
            StringBuffer buffer = new StringBuffer();
            String line = null;
            while ((line = reader.readLine()) != null)
            {
                Log.e("Line===", line);
                buffer.append(line);
            }
            resultString = buffer.toString();
        }
        catch (ClientProtocolException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        catch (IOException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return resultString;
    }
    @Override
    protected void onPostExecute(String result)
    {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        //result will contains the response JSON
    }
}

Here on the onPostExecute method we will get the resultant JSON in result variable.
