I think op means micro-g Soo on Android many non basic features are enabled through Play Services. It is basically a huge library from Google that auto updates itself. Chromecast is a good example of a feature delivered entirely through play services. Google login also works that way. Many apps leverage Play Services in some way. It is common to check your play services version at startup and ask the user to update them if they are out of date compared to what your app targets. Micro-g reproduces the Play Services API and tries to deliver an open source equivalent to some of its features. I don't really buy the argument that Play Services nullifies AOSP in any way but it is interesting to see another alternative (amazon also has a similar project) that is open source.
