Question

отправлено push-уведомление с использованием Firebas e через PHP API. Передача параметров с android и данные попадают на push-уведомление, отправленное на android. Объявление получает данные из базы данных и данные о прохождении в классе Firebas e и отправляет их на уведомление в строке android.in 3, что я не знаю.
