Аудио воспроизводится, но не отображается в уведомлении Android API 34

Цитата

Сообщение Anonymous » 29 июн 2024, 15:34

после обновления моего API до версии 34, когда я играю, звук воспроизводится, но не отображается в списке уведомлений. поэтому я не могу остановить звук, даже когда закрываю приложение, и я не вижу никаких ошибок в Logcat, чтобы узнать, откуда возникла ошибка. как исправить это при воспроизведении аудио, чтобы отображалось уведомление при нажатии значка в уведомлении, чтобы остановить аудио
я уже добавил Service в манифест.xml

Кто-нибудь может помочь, пожалуйста
Я уже искал это в Google, но не нашел, что поможет мне это исправить, потому что, когда я пытаюсь нажать «Аудио», это Воспроизводится без ошибок, но не отображается в уведомлении.
