In this two-part guide, we expand the Phoneword application we created in the Hello, Android guide to handle a second screen. Along the way we introduce the basic Android Application Building Blocks and dive deeper into Android architecture as we develop a better understanding of Android application structure and functionality.
In the first part of this guide we’ll add a second screen to our Phoneword application to keep track of the history of numbers called using our app. The final application will have a second screen that displays the call history.
In the second part of this document, we review what we’ve built and discuss architecture, navigation, and other new Android concepts that we encounter along the way.
