1. Preface

As mobile app development continues to evolve, Google has introduced Jetpack Compose, a brand-new declarative UI framework designed to simplify the process of developing Android UIs. Based on Kotlin, Compose UI offers a more intuitive and reactive approach to building interfaces. Part 1 introduced A Comprehensive Guide to Building Your First Compose Application, and this article will provide a detailed overview of the toolset and learning resources for Compose UI.

2. Toolset

Jetpack Compose UI is a modern toolkit for building native interfaces on Android. Here are 10 recommended Compose UI toolsets that range from design to development, debugging, and testing. These tools can help developers increase their productivity and enhance the user experience.
