Lab 2: CodepathMail

Time Spent: Around 2 1/2 hours

In this lab, we'll build a simple clone of the very popular Gmail app.

The main purpose of this lab is to understand how to implement the most common type of screen in mobile apps: scrolling lists.

In Android, RecyclerView is what allows us to easily display a list of data, and we'll utilize this lab to get comfortable working with RecyclerViews.
