Android is Google mobile operating system and the platform behind most of the world smartphones. Native development is done in Kotlin or Java with Android Studio, the Jetpack libraries and the Compose UI toolkit.
This category covers native Android work: the activity and fragment lifecycle, Jetpack Compose, background execution and coroutines, storage and networking, and publishing to Google Play. Cross-platform routes to Android — React Native, Flutter, Ionic — have categories of their own.
