So I think I am going to resume the project I almost started back when my wife got her tablet, I am going to make an app/program for the tablet and our phones just to see if I can. Then maybe tryout the iOS SDK, but for that one I have to install a iOS X on an virtual machine so I can running the SDK. Anyway I am in the process of reading over the install process's, and downloading all the software I need. I am at Java and Eclipse right now, and am looking at all these different packages and wondering which ones are essential, or useful, and which are not needed, and a waste? Like if I got the one for Mobile Developers, would I need 4.2 also? Or the IDE for Java Developers? Or are they included in those packages? I've got a couple sites I am reading through with installation, and set up plans, but does anyone have any tips, do's/don't's, words of wisdom, learn from my mistake's they want to share?
