That is my guide when I started how to setup Android and Eclipse. I am so happy it's 100% working now, i.e. both Android and Eclipse are "communicating" very well (just trying to do very basic programming though). And what's so cool about this is that I'm using the same Eclipse version for my J2ME projects, so I am using one Eclipse version for both projects.
I don't know if there is a plugin of Android for the Netbeans IDE. I also want my NetBeans to recognize Android projects, but unfortunately, I can't find one on the Web. (Any tips anyone? Thanks). I hope the link will help.
Thank you and good luck to your Android development.
God bless everyone.
