Answer 1

Измените задачу async следующим образом: Выполнение фонового метода asynctask выполняется в NON Threading, поэтому мы не можем изменить ui-элементы из doInbackgroud, поэтому мы должны вернуть этот результат, чтобы результат включался в метод postExecute в качестве параметра то мы можем изменить интерфейс

       return null; 
     } 
     protected void onPostExecute(JSONObject result) { 
      //Parse and update the UI 
       jsonParsed.setText(OutputData); 
      } 
     } 
    }

Answer 2

jsonParsed.setText(OutputData);
Вы просто поставить выше линии в onPostExecute метод после того, как hint_data.setText(OutputData);, и вы получите идеальный выход.
А также удалить jsonParsed.setText(OutputData); линия из doInBackground метода.

Answer 3

Удалить ниже линии от метода doInBackground

jsonParsed.setText(OutputData); 

Вы не можете коснуться вид из вне основного потока.
