I recently got interested in Android development and wanting to learn (and if permits, a career shift! ) this awesome mobile programming.
If you look around the internet, most of the references that you will find there are mostly about Android Development from Eclipse IDE and it is also the IDE of choice by Android Developers see here. As for me, I want it somewhat "from scratch" that way I'll learn how an Android Application execute.
Android Developers provided a Developers Guide when Building and Running an Android Application from Command Line, but for a newbie like me with roughly 5% Android development knowledge, it is too advance for me to understand those. That's why I decided to do a step-by-step setting up an android development environment in 4 easy steps.
