So, starting to develop with Google Android, the more convenient choice is certainly to stay open source with Eclipse. If like me you can't develop smoothly as long your IDE is not customized, here there are some suggestions from which to take inspiration (or I hope so).

I've also installed a new theme called Dark Juno from here https://github.com/rogerdudler/eclipse-ui-themes. Clone the repository, follow easy instructions in the README file and set the theme in Window -> Preferences -> General -> Appearance.
Finally I suggest you to use a better programming font like Monoco, available here for example. Also this is done in the preference window under Appearance -> Colors and Fonts section. If you don't like it, check out some good blog post on the web about this argument, e.g. this one.
