Answer 1

To answer the original question:

There seems to be no built-in way on Android O to get a single line, ongoing notification for a ForegroundService. One could try adding a custom design, but as different phones have different designs for notification, that solution is hardly a good one.

There is hope, however :)

On Android P the notification in a NotificationChannel of IMPORTANCE_LOW with a priority of PRIORITY_LOW is compacted to a single line even for a ForegroundService. Yeah!!
