Notes:
Spent around 3 hours to watch the walk-thought videos to set up "Android Studio" and type codes for the initial 2 user stories. Spent around another 3 hours to design the second activity of edit item and did research on "StartActvityForResult()", "Intent" and "Intent.putExtras()". This is a very out-standing introductory tutorial for a beginner toward Android development.
