Android Crash Course checklist

A list of basic topics that are fundamental to Android application development.

I recently have the opportunity to introduce Android development to a group of developers who want to hone their skill in Android development and learning it from the ground up. So I made the list that lists some of the common topic found when developing Android application to act as achievement confirmation and milestone.

Why created my own and not using Google's own material? This checklist does not go into details in any subject at all. It is meant to accompanied new developer when adventuring in Android tutorial on http://d.android.com as that can overwhelm unprepared newcomers quite easily.

The list is structured so that part of it reflect what you would learn from Google's Android Application Development course on Udacity so those learning can recollect what they learned as a confirmation.

I hope someone find it useful. Feedback welcome :)
