GPS

I'm trying to get GPS working on Android but I'm stuck with a compilation error?

Maybe

CerberusGame

instead of

cerberusGame

?

No sadly that didn't fix it, but that's one thing for sure. I'll try to dig into this later as my Android skills are severely lacking at this stage I need to brush them up first.
