i'm trying to get json data from website that i build using Yii framework.

when i open mozilla and i go to http://localhost/restayii/index.php/employee/getemployee?id it's showing employee json data.

this is my employee jsondata :

{"employee":[{"id":"1","departmentId":"1","firstName":"Hendy","lastName":"Nugraha","gender":"female","birth_date":"1987-03-16","marital_status":"Single","phone":"856439112","address":"Tiban Mutiara View ","email":"hendy.nugraha87@yahoo.co.id","ext":"1","hireDate":"2012-06-30 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"2","departmentId":"2","firstName":"Jay","lastName":"Branham","gender":"male","birth_date":"0000-00-00","marital_status":"Single","phone":"0","address":"","email":"jaymbrnhm@labtech.org","ext":"2","hireDate":"0000-00-00 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"3","departmentId":"3","firstName":"Ahmad","lastName":"Fauzi","gender":"male","birth_date":"0000-00-00","marital_status":"Single","phone":"0","address":"","email":"ahmadfauzi@labtech.org","ext":"3","hireDate":"0000-00-00 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"4","departmentId":"1","firstName":"Henny","lastName":"Lidya Simanjuntak","gender":"female","birth_date":"1986-01-27","marital_status":"Married","phone":"2147483647","address":"Tiban Mutiara View ","email":"henokh_v@yahoo.com","ext":"1","hireDate":"0000-00-00 00:00:00","leaveDate":"0000-00-00 00:00:00"},{"id":"5","departmentId":"2","firstName":"sfg","lastName":"sfgsfg","gender":"male","birth_date":"2013-10-23","marital_status":"Single","phone":"356356","address":"sfgsfg","email":"sfgsfg","ext":"4","hireDate":"2012-05-30 00:00:00","leaveDate":"0000-00-00 00:00:00"}]}

this is on Android Activity.

(On Android)

<strong>The problem is:</strong>

when this app launch, and i clicked button refresh, it's not showing table row that contains employee json data. but there's no error too on the logcat. Is it wrong with my url on class Task extends AsyncTask ??

or should i replaced it with the same link just when i open it from mozilla http://localhost/restayii/index.php/employee/getemployee?id??


I already change the url to http://localhost/restayii/index.php/employee/getemployee?id inside Task Class extends AsyncTask, but is still won't get employee json data from localhost.

please, Any help would be greatly apreciated. thanks


i already find an answer. my problem is in sub class Task extends asyntask and also in jsonParser sub class.

private class Task extends AsyncTask<JSONObject, Void, JSONObject>{ @Override protected JSONObject doInBackground(JSONObject... params) { try { JSONParser json_parser = new JSONParser(); json_object = json_parser.getJson(url); } catch (Exception e) { e.printStackTrace(); } return json_object; } @Override protected void onPostExecute(JSONObject result){ LoadEmployee(result); } } private class JSONParser { ..... public JSONObject getJson(String url) { try { HttpClient httpClient = new DefaultHttpClient(); HttpGet httpget = new HttpGet(url); HttpResponse httpResponse = httpClient.execute(httpget); BufferedReader rd = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent())); StringBuffer hasil = new StringBuffer(); String line = ""; while ((line = rd.readLine()) != null) { hasil.append(line); } json = hasil.toString(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } try { jObj = new JSONObject(json); } catch (JSONException e) { e.printStackTrace(); } return jObj; } }

now i can get all json data from my Yii web service. hope it will help someone.


I know that, you have to refresh android screen when you called an ajax data... May be this will show you the way...


Now you use wrong URL in the AsyncTask. The right URL is something like http://localhost/restayii/index.php/employee/getemployee?id
