In this two-part guide, you expand the Phoneword application that you created in the Hello, Android guide to handle a second screen. Along the way, this guide will introduce the basic Android Application Building Blocks and dive deeper into Android architecture as you develop a better understanding of Android application structure and functionality.
Part 1: Quickstart
In the first part of this guide, you'll add a second screen to the Phoneword application to keep track of the history of numbers called from the app. The final app will display a second screen that lists the call history.
Part 2: Deep Dive
In the second part of this document, you will review what you've built and discusses architecture, navigation, and other new Android concepts that are encountered along the way.
