Kickstart Your Android Journey by Building Your First Android Application with Jetpack Compose

Kickstart your Android development journey with Jetpack Compose by building your first interactive app! This codelab introduces you to Compose’s declarative UI, key components like Text, Button, and TextField, and styling with Modifiers. You’ll learn recomposition, manage UI state with remember and mutableStateOf, and explore state hoisting for reusable composables. You'll also implement a ViewModel to retain state across recompositions and configuration changes. Finally, you'll handle user interactions, preview UI in Android Studio, and debug on an emulator or device, gaining essential skills to build modern Android apps.
