Jetpack Compose
Jetpack Compose is a modern declarative UI toolkit for building native Android applications using Kotlin. It simplifies UI development by allowing developers to describe their user interface as composable functions that automatically update when data changes. It replaces the traditional imperative XML-based view system with a more intuitive and efficient code-driven approach.
Developers should learn Jetpack Compose for new Android projects or when modernizing existing apps, as it reduces boilerplate code, improves performance with efficient recomposition, and enhances developer productivity with live previews and state management. It is ideal for building responsive and dynamic UIs, especially in apps targeting Android 5.0 (API level 21) and above, and is the recommended UI framework by Google for future Android development.
