Answer 1

Вы пытаетесь получить доступ ключа, который не существует.

Форма ответа сервера заключается в следующем:

D/Login attempt﹕ {"data":null,"message":null,"status":"Failed"} 
W/System.err﹕ org.json.JSONException: No value for success 

Вы можете проверить, если он существует, прежде чем использовать его, как это:

if (json.has("status")) { 
    String status = json.getString("status")); 
} 

UPDATE:
Вы можете изменить следующий тег:

private static final String TAG_SUCCESS = "success"; 

Для этого:

private static final String TAG_SUCCESS = "status"; 

Возможно изменить имя переменной, скажем, TAG_STATUS
