Но я до сих пор путают BCZ до этого я делаю так много времени и JSON массива JSON объект, но никогда не увидеть такого рода ошибки.

Итак, теперь мой вопрос в том, что происходит с этой проблемой?

Сколько раз этот код становится выполнен? –

ваше решение toString помогло мне решить мою ошибку stackOverflow, которую я получал для простого json с json-массивом. Спасибо тонну :) = –

Вы создали круговую структуру: j_class содержит j1 и j1 содержит j_class.

Возможно, вы хотели поставить j1_class вместо j_class.

      JSONObject messageObject = new JSONObject(); 
      messageObject.append("date", smsdate);

      JSONObject callObject = new JSONObject(); 
      callObject.append("date", calldate);

      locationObject.append("latitude", latitude); 
      locationObject.append("longitude", longitude); 
      locations.put(locationObject.toString()); 


     } 
     json.append("msisdn", msisdn_); 

    }catch(JSONException je){ 
     je.printStackTrace(); 
    } catch (Exception se) {

Также не забудьте сделать Stringify them.See выше фрагменте кода: (ToString());) Надеюсь, что это помогает кто-то там;)
