I'll be offering an Android Application Development course this coming fall. The prerequisites are Comp 245 (Data Structures) and Comp 345 (OOP) or consent of the instructor.
I'm toying with the idea of offering an on-line, not-for-credit version of the course which will run concurrently with the live course. I would create a series of 30 minute videos that participants would watch on their own time, and then there would be a set time each week when everyone taking the course would join together in an on-line environment. I would be able to answer questions and go into more detail about the week's topic. There would also be some homework. Let me know if you think this is something you would be interested in. The fee would probably be around $150-200.
Some tutorials I created for developing an Android tic-tac-toe app are available on Google Code University. The tutorials teach you how to render graphics, save state information, play audio files, etc. I created the tutorials when I taught the first Android/iPhone programming course last spring. I'll likely be augmenting the tutorials this fall.
I ran across this article last week from the Wall Street Journal reporting that smartphone developers are increasingly in demand (see the figure below). Just a little more motivation to take my course!
