Android SDK - Subscribe to Cloud event?

I notice the iOS sdk has a built-in way to subscribe to events:

but I don’t see this listed in the docs for Android.
Is it supported (even if not documented)? If not, do you plan to add it? E.g. I see some mention of it in EventsDelegate.java but these docs indicate it’s still “coming soon”

Thanks! Looking forward to tinkering!

p.s.

My use case, fwiw, is that I’d like the Android App to respond to when a user presses a button attached to the Photon.

It’s implemented in version 0.3.0 of the SDK(at least that’s in the CHANGELOG). Although I can’t figure out how to use it. I’m trying to receive notifications when button is pressed.
