Будильник не звонит в указанное время ⇐ Android

[Anonymous]

Я пытаюсь создать небольшое приложение для сигнализации для Android, я новичок в разработке для Android, заранее извините, если это глупый вопрос. проблема, с которой я столкнулся, заключается в том, что будильник не начинает воспроизводиться по достижении установленного времени.
Вот код

Я также пытался проверить журналы, но кажется, что сообщение не регистрируется. Я совершенно не понимаю, почему это происходит, любая помощь, совет или подсказка будут ценю.
Спасибо
