Late response (new to forum), but hope this helps new programmers.

Until Studio is out of beta testing, you are best of starting with Eclipse (as you did). You can easily download it, as well as all required SDK packages from the Google developer page: Android SDK | Android Developers

On this same page, you will also find a training page, with many examples to get you started, including a great 'My first app' tutorial to get you on your way. You can find it here: Getting Started | Android Developers

After this, stackoverflow is a great site to find answers to your programming questions. Dont start by making threads, start by using the search function, your question is most likely already posted.

Good luck and have fun!!
