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.

Exploring Interoperability APIs

The aim of this book is to show you how to develop beautiful, fast, and maintainable Jetpack Compose apps. The previous chapters helped you get familiar with the core techniques and principles, as well as important interfaces, classes, packages, and—of course—composable functions. The remaining chapters cover topics beyond a successful adoption of Android’s new declarative user interface toolkit.

In this chapter, we are going to look at AndroidView(), AndroidViewBinding(), and ComposeView as the interoperability application programming interfaces (APIs) of Jetpack Compose. The main sections we will cover are the following:

  • Showing Views in a Compose app
  • Sharing data between Views and composable functions
  • Embedding composables in View hierarchies

We start by looking at how to show a traditional View hierarchy in a Compose app. Imagine you have written a custom component (which, under the hood, consists of...
