At least one team at Google has used libGDX (on top of RoboVM): Ingress uses libGDX for their iOS and Android clients. RoboVM is a very cool project. We ended up on Xamarin for the cross-platform project we were working on here internally, but, had RoboVM been a little more mature when we were evaluating cross-platform projects (this was around April of last year), it would've most likely been our first choice instead (we have a lot more in-house Java expertise than C#).
