title: Android 8 Foreground Service with Notification Channel
body: <p>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.</p>
  
  <p>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.</p>
  
  <p>What happens in this case? Will the service become a background service? Does it get killed? I haven't found a documented answer.</p>
