Android Studio Overview
Android Studio is Google's official integrated development environment for building Android apps, available free for Windows, macOS, and Linux. It is built on JetBrains' IntelliJ IDEA platform and adds Android-specific tooling: a visual layout editor, the Android Emulator for testing on virtual devices, the Gradle build system, an APK/bundle analyzer, and deep integration with the Android SDK and debugging tools. It supports Kotlin and Java and includes intelligent code completion and refactoring from the IntelliJ base. The download is large because it bundles the IDE and SDK components; the offline installer sets up the IDE without a network connection, though SDK components are fetched separately.
