Piszę aplikację timera, z usługą i sygnałem dźwiękowym co 30 sekund (w rzeczywistości jest to dropdown, który zmienia ten czas).ToneGenerator spowalnia aplikację bardzo mocno
Jednak po wygenerowaniu sygnału dźwiękowego aplikacji sygnał dźwiękowy trwa bardzo długo i powoduje zatrzymanie aplikacji, ostatecznie (po około 5 sekundach) kończy się, a następnie odliczanie czasu. Dlaczego to się dzieje? Jak to naprawić? Tu jest mój kodu:

mogę dodać moje AndroidManifest jeśli to konieczne. Na AndroidStudio na debug daje mi następujące informacje, gdy to się dzieje:
I/Choreographer: Skipped 35 frames! The application may be doing too much work on its main thread.
I/Choreographer: Skipped 175 frames! The application may be doing too much work on its main thread.
I/Choreographer: Skipped 44 frames! The application may be doing too much work on its main thread.
powinienem robić sygnału dźwiękowego w służbie, czy coś?
Dodam, że jestem przekonany, że to jest z ToneGenerator, skomentowałem wszystkie części dźwiękowe i opuściłem wibrator, a kiedy działa, nie ma problemu. Ale ToneGenerator i Ringtone zarówno spowodowany ten problem
