Once you figure it out, doing it when you receive a push notification is a cake walk .. Good luck in exploring the same.

05/03/2021, 9:32 AMI think you misunderstand me. The problem is not to find the current activity from service. although, I have done it before and It does not require any permission and I only use ActivityManager to do that.
I just have searched and I have found two solution for that:
1. use EventBus library
2. register a BroadcastReceiver in my activity and send broadcast to handle it in activity.
which solution is better? Is it safe to use EventBus library for only one usage?

The activity or it's ViewModel collect from that flow.
If you look at the docs for SharedFlow they show you how to use it as an event bus.
