Stuck getting started with API

[montgoss]

I'm trying to integrate Flic in an Android app.
I can successfully open the "button grabber". But when I select a connected button, I briefly see a dialog that says "Downloading key...", and then an error dialog that just says "Unknown error". I never get any further and I have no idea what the error is. Any idea what is causing this unknown error or how I might figure out what the error is.

Is it just me? It works for everyone else?!
