Training | Jetpack Compose in depth

Jetpack Compose from zero to 100 course. Learn about the internals of the library, it's compiler, and how to use it to write fully fledged Android UIs.

Overview

Compose is a declarative UI toolkit that is about to kick-off for Android. It's the future of Android UI, providing declarative APIs to create layouts of any complexity, manage and observe state changes automatically. Its API surface leverages immutable view state and its compiler is oriented to unlock efficient UI rendering and updates. Compose requires Kotlin and removes the duality of code and XML we had prior to what is imposed by the Android layout system

In this course, you will learn the guts of Compose, its purpose, and how it can be used for your day-to-day Android apps.

Prerequisites

  • Previous experience with Kotlin and Android knowledge.
  • Familiarity with other declarative UI frameworks like React, Flutter or similar would be helpful, but not required.
  • A computer with Android SDK and Android Studio or IntellIJ.
