It seems like every tutorial that I can find has a different, usually old, way of doing it. For example, even Google's LiveCard page has an example where they tell you to implement LiveCardCallback , however the link they give is dead, and that class doesn't exist in the GDK.
I also found a gdk apidemo on github, but most of those examples seem to be outdated?
Any good resource for an Android developer just starting out on Glass?
