I'm trying to set up a google play service library in my app and I need to download the basegameutils. But I really have no idea how to download this sample on this site... It really seems a mystery to me.. EDIT: I was overlooking the download button on the lower right side of the screen.
On the right hand side column near the bottom, there is a button that says Download zip. If you click that it will download the entire android-basic-samples folder. Within that folder, you will fine BaseGameUtiles under BasicSamples > Libraries > BaseGameUtils.
