This material is out of date by now. We recommend checking out the Codename One Academy.
We just released a new online course on Udemy called "Learn Mobile Programming By Example With Codename One". Before a single day went by we already have over 600 students enrolled which is pretty cool. This course is based on the videos we made for the Dr. Sbaitso demo and the PropertyCross demo with some additional videos thrown in to tie everything together and introduce Codename One.
We'd appreciate if you would help us spread the word about this and inform people about this course. FYI in case you are new here and missed it, we also have another free course on Udemy covering the photo share app. That course is also available on youtube, we also have the Codename One 101 course which is free for pro subscribers.
