org.json.JSONException: значение MySQL типа java.lang.String не может быть преобразовано в JSONObject.

Я подключаю внешнюю базу и Android с помощью php. Я подтвердил, что данные, введенные на Android, вставлены в таблицу mysql. Но попадание в ошибки в JSONObject. Я следовал этому уроку. Я просто превратил локальную базу данных во внешнюю базу данных. - https://github.com/GaKaRi/gakari_android/tree/master/Proj_Manager_v3

Буду признателен, если вы поможете мне.
