Android UI Development with Jetpack Compose

By: Thomas Künneth

Overview of this book

Jetpack Compose is Android’s new framework for building fast, beautiful, and reliable native user interfaces. It simplifies and significantly accelerates UI development on Android using the declarative approach. This book will help developers to get hands-on with Jetpack Compose and adopt a modern way of building Android applications. The book is not an introduction to Android development, but it will build on your knowledge of how Android apps are developed. Complete with hands-on examples, this easy-to-follow guide will get you up to speed with the fundamentals of Jetpack Compose such as state hoisting, unidirectional data flow, and composition over inheritance and help you build your own Android apps using Compose. You'll also cover concepts such as testing, animation, and interoperability with the existing Android UI toolkit. By the end of the book, you'll be able to write your own Android apps using Jetpack Compose.

Chapter 9: 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 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 are listed here:

  • 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 several UI elements...
