Need to get message back to Forms PCL from Android Prj

I have a RadiusNetworks IBeaconAndroid running in my main android project, works great.
But when I need to send an event back to the UI when a beacon comes in range.
I tried to use MessagingCenter to send a message from Androd prj to the Forms PCL prj but it would cause a recursive

How can I do this?
I don't think I need a custom render since I just want to use normal forms label.

Ed,
