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.

This chapter explored the predefined layouts of Row(), Column(), and Box(). You learned how to combine them to create beautiful UIs. You were also introduced to ConstraintLayout, which places composables that are relative to others on the screen and flattens the UI element hierarchy.

The second main section explored why the layout system in Jetpack Compose is more performant than the traditional View-based approach. We looked at some of the internals of the Compose runtime, which prepared us for the final main section of this chapter, Creating custom layouts, where you learned how to create a custom layout and thus gain precise control over the rendering of its children.

The next chapter, Managing the State of Your Composable Functions, will deepen your knowledge of state. We will examine the difference between stateless and stateful composable functions. Also, we will look at advanced use cases such as surviving configuration changes.
