How to read json array in Android

Question

I am facing here problem in reading a json array which is got from server : http://XXX.XXX.XXX.XXX:9090/appsapi/rest/services/getStudentPersonalDetails/123789 , this json array doesn't have json object in it. It is like below.:

{"password":"raj","address":"dfsaf","state":"tamilnadu","image":"Bindu Appalam.jpg",
 "dept":"BE(Mech)","fname":"fasdf","mname":"saffd","dob":"14/12/1951","sex":"Male",
 "email":"[email protected]","contact":"212121212545855555545","city":"dsfadf",
 "pin":"600106","sname":"fdjsf","studid":"123789"}

I want to parse it..

I have tried to get the json array like below from httpclient request :

try {

            System.out.println("url tt : "+url);
            // http client
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpEntity httpEntity = null;
            HttpResponse httpResponse = null;

            System.out.println(" Urls Input to "+url);

            // Checking http request method type
            if (method == POST) {
                HttpPost httpPost = new HttpPost(url);
                // adding post params
                if (params != null) {
                    httpPost.setEntity(new UrlEncodedFormEntity(params));
                }

                httpResponse = httpClient.execute(httpPost);

            } else if (method == GET) {
                // appending params to url
                System.out.println(" Params Valyes "+params);

                if (params != null) {
                    String paramString = URLEncodedUtils.format(params, "utf-8");
                    url += "?" + paramString;
                    System.out.println(" Params String "+paramString);
                }
                HttpGet httpGet = new HttpGet(url);
                httpResponse = httpClient.execute(httpGet);
            }

            httpEntity = httpResponse.getEntity();
            response = EntityUtils.toString(httpEntity);

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

but got below error in response :

Looks like you are getting 404 not found on your service call? It cant parse it because it cant be found — riggaroo

A JSON Object starts with a { and ends with a } while a JSON Array starts with a [ and ends with a ].

In your case, change your code to have a JSONObject instead.

JSONObject json = new JSONObject(jsonString);
JSONArray jArray = json.getJSONArray("list");

System.out.println("*****JARRAY*****"+jArray.length());
for(int i=0;i<jArray.length();i++){


 JSONObject json_data = jArray.getJSONObject(i);
 Log.i("log_tag","_id"+json_data.getInt("account")+
  ", mall_name"+json_data.getString("name")+
  ", location"+json_data.getString("number")+
  ", telephone"+json_data.getString("url")+
  ",----"+json_data.getString("balance")+
  ",----"+json_data.getString("credit")+
  ",----"+json_data.getString("displayName")
 );

}

In your code, there is no json array present, it is json object with name value pair data. So you have to parse JSONObject not JSONArray.

Like:

JSONObject json = new JSONObject(jsonString);

String password = json.getString("password");

Similarly you can get all the values of the object.
