}

Для информации, я должен получить данные с другого URL-адреса веб-сервера (http://........................./lastClock.php), а имя объекта из таблицы - dclkrec (представлять дату) и cclktime (представлять время).

Любая помощь от вас, ребята, будет очень признательна. Заранее благодарю.

Здесь вы делаете много переосмысления колес. Существуют инструменты для создания сетей и сериализации/десериализации данных.

Для сетей я могу рекомендовать Retrofit

Работа с JSON объектов Gson

Попробуйте это и ваша жизнь будет намного проще. Доверьтесь мне. Стоит инвестировать немного времени.
