parsing json webservices in android for my format

Question

I am developing a simple login application. My JSON web service returns the username. Here's the JSON code's format:

[{"demologin":{"username":"demoname","id":100}}]

And here is my code:

private class LongRunningGetIO extends AsyncTask <Void, Void, String> {

    protected String getASCIIContentFromEntity(HttpEntity entity) throws IllegalStateException, IOException {
       InputStream in = entity.getContent();
         StringBuffer out = new StringBuffer();
         int n = 1;
         while (n>0) {
             byte[] b = new byte[4096];
             n =  in.read(b);
             if (n>0) out.append(new String(b, 0, n));
         }
         return out.toString();
    }

    protected String doInBackground(Void... params) {
         HttpClient httpClient = new DefaultHttpClient();
         HttpContext localContext = new BasicHttpContext();

         username=txtUserName.getText().toString();
         password=txtPassword.getText().toString();



         String url="MY URL HERE";
         HttpGet httpGet = new HttpGet(url);

         String text = null;
         String result = null;
         String webusername=null;
         int webuserid;
         ArrayList<String> desc=new ArrayList<String>();

         try {

               HttpResponse response = httpClient.execute(httpGet, localContext);
               HttpEntity entity = response.getEntity();
               text = getASCIIContentFromEntity(entity);



                   JSONArray ja = new JSONArray(text) ;
                   // ITERATE THROUGH AND RETRIEVE CLUB FIELDS
                                int n = ja.length();
                                for (int i = 0; i < n; i++) {
                                    // GET INDIVIDUAL JSON OBJECT FROM JSON ARRAY
                                 JSONObject jo = ja.getJSONObject(i);

                                 webusername= jo.getString("demologin");
                                 webuserid= jo.getInt("id");

                                }
         } catch (Exception e) {



                   e.getLocalizedMessage();
                   }    
         return webusername; 
    }   
    protected void onPostExecute(String results) {
        if (results!=null) {

            String sendusername=results;
            Intent inte=new Intent(Login.this,FrontPage.class);
            inte.putExtra("displayusername", sendusername);
            startActivity(inte);


        }
        else
            Toast.makeText(getApplicationContext(), "Invalid user", Toast.LENGTH_LONG).show();


        }
}

The problem here is that I have no idea how to get the username into a string and pass it over the web. Does anyone have an idea about how this could be done?

see this. This would be the opposite of what your trying to do. http://stackoverflow.com/questions/8706046/create-json-in-android — Fahad Ishaque, Feb 28 '13 at 11:43

I think this post will help you, here the string manupulation is done on a string returned fro the wsdl, you can use the same string split function to split your results process an array returned by web service

Please stop creating tag wikis for [incorrectly spelled tags](http://stackoverflow.com/tags/druapl/info). They will be deleted and we don't want people to use them. – Ben Mar 28 '13 at 11:26
In fact, please stop creating tag wikis for non-existent tags. – Ben Mar 28 '13 at 11:28
Ok but it would be good if the ppl who got more reputation remove them. – Amalan Dhananjayan Mar 28 '13 at 11:31
