问题
I want to start a foreground service in Android 8 and I want to know how are foreground services compatible with the notification channel system.
Let's say we start a foreground service, then we immediately create the required notification and assign it to a notification channel. Suddenly, the user decides to go into System Settings and disable the notification channel.
What happens in this case? Will the service become a background service? Does it get killed? I haven't found a documented answer.

Foreground service notification:
Disable notifications:
Android 8 shows this notification after few seconds (when you send your application to background):
