Today Oracle published the first in a series of online eLearning training materials. The ADF Academy presents free and online : Developing Applications with ADF Mobile. The main goal is to deliver technical training material to everybody that needs it. You get an online training, where you can view audio and video to learn ADF. Whenever you want to you can stop the recordings to try out everything that you learned so far, or perhaps to get a drink. Developing Applications with ADF Mobile is available here . Take to opportunity and learn to work with a great framework to develop mobile applications for iOS and Adroid. Also keep an eye on lucbors.blogspot.com for more ADF Mobile related content.
