TLDR: Single-shot event bus with priority-based collectors?

I have an app-wide single-shot event bus which exposes a Flow of events and is collected in a (Android) lifecycle-way such that whichever Fragment is visible (let’s assume only one visible at a time) will collect the event and handle it. However, there are some fragments where it doesn’t make sense to collect these events but instead have some generic behavior which would make more sense in the Activity (assume single Activity app).

I’m trying to work out how to do this. Essentially, if nothing collects an event (ideally: no collector is active, or (less ideally) perhaps using a timeout) then let some Activity collector handle it instead. Or perhaps the Activity collector somehow has lower priority than a visible-fragment collector.
