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.

I also showed you that you can make your composable functions more reusable by passing logic as parameters, rather than implementing it inside the composable. The previous section explored the integration of a Compose UI hierarchy in activities concerning how to retain user input. We looked at the differences between remember {} and rememberSaveable {}, and I gave you a glimpse of how bigger Compose apps can benefit from ViewModel classes.

Chapters 1 to 5 introduced you to various aspects of Jetpack Compose, such as composable functions, state, and layout. Chapter 6, Putting Pieces Together, focuses on one app, providing...
