Overview of this book

Compose has caused a paradigm shift in Android development, introducing a variety of new concepts that are essential to an Android developer’s learning journey. It solves a lot of pain points associated with Android development and is touted to become the default way to building Android apps over the next few years. This second edition has been thoroughly updated to reflect all changes and additions that were made by Google since the initial stable release, and all examples are based on Material 3 (also called Material You). This book uses practical examples to help you understand the fundamental concepts of Jetpack Compose and how to use them when you are building your own Android applications. You’ll begin by getting an in-depth explanation of the declarative approach, along with its differences from and advantages over traditional user interface (UI) frameworks. Having laid this foundation, the next set of chapters take a practical approach to show you how to write your first composable function. The chapters will also help you master layouts, an important core component of every UI framework, and then move to more advanced topics such as animation, testing, and architectural best practices. By the end of this book, you’ll be able to write your own Android apps using Jetpack Compose and Material Design.

Building a Real-World App

The previous chapters explored various aspects of Jetpack Compose. For example, Chapter 2, Understanding the Declarative Paradigm, compared the traditional view system to composable functions and explained the benefits of the declarative approach. Chapter 4, Laying Out UI Elements in Compose, gave you a solid understanding of important built-in layout composables, such as Box(), Row(), and Column(). In Chapter 5, Managing State of Your Composable Functions, we looked at state and learned about the important role it plays in a Compose app.

Now, it’s time to see how these key elements work together in a real-world app. In this chapter, you will learn how Compose apps can be themed. We will also look at Scaffold(), an integrational UI element that picks up quite a few concepts that were originally related to activities, such as toolbars and menus. Finally, we will learn how to add screen-based navigation.

In this chapter, we will cover the following...
