We haven't tested on android yet and as you can see it's trying to initialize 
the desktop OpenGL 3.2 based helper class for some reason. Paul is looking 
into issues on running on ES 2 based systems. Once that is working making it 
work on Android should not be difficult.

I'd expect basic support before Christmas for Android and also hopefully iOS 
once James is back from the US DevDays.

Of course if you want to help solving these issues then you're more than 
welcome to help out :)

Cheers,

Sean
