I spent around 5 hours making the native google analytics work with windows phone 8, finally got it to sent a request to google, was pretty satisfying seeing the live update show on up on Google analytics, it needs work but work and needs more testing but I think it could also be used for pretty much any version of cocos2d-x as it is pure c**, the httprequest would need to be switched to curl or some other class possibly.
If anyone’s interested, I can upload the beta
I repeat I converted c** part not c#
