* Added Codename One books

Codename One is an Open Source Java platform for mobile devices (iOS, Android, Windows etc.). The developer guide is created in the open as part of the Codename One wiki. The Uber Clone book isn't free but the first 2 chapters which are about 100 pages are free to download without an email address or anything. I hope the latter is considered free enough for this list
