Exactly this. I've never heard of CloudRails, from my own development experience, on conferences or meetups or posts. Retrofit (1&2, Volley, those are the libraries that deserve mention there. "Database" category having just two libraries is like someone didn't want to bother, since Android has a lot of ORM libraries and also databases like Realm. Date & Time doesn't even have Joda-Time for android, DI links to Dagger which is deprecated in favour of Dagger 2, Functional includes only Retrolabmda, no even mention of RxJava and all the libraries surrounding it, Camera is missing some most popular camera libraries, Logging doesn't include the most used one - Timber, Image doesn't include Picasso or UIL... I don't feel like scrolling anymore, there is a lot missing, especially since the list is called "Best Android Libraries".
