Building Your First Mobile App in Compose Multiplatform (CMP) for Android and iOS with Kotlin Multiplatform (KMP)

This codelab is designed to guide you through the exciting journey of creating your first mobile application using Compose Multiplatform, a powerful toolkit by JetBrains that enables you to build native UIs for both Android and iOS using a single codebase. You'll start by setting up your development environment, followed by creating your first cross-platform app. You'll then delve into building a shared UI in Kotlin for both platforms and learn to fetch and display data, including images, from APIs using the Ktor Networking Library. By the end of this codelab, you'll have a solid foundation in Compose Multiplatform, enabling you to develop robust and efficient cross-platform mobile applications.
