Android Studio is the official Integrated Development Environment (IDE) for Android app development. It is based on IntelliJ IDEA and provides all the necessary tools for developing Android apps, including a robust code editor, an Android emulator, and tools for building and deploying APK files. Android Studio also offers specialized features such as Gradle-based build support, Lint tools for improving code quality, and templates to quickly create Android components. Additionally, it integrates seamlessly with the Android SDK (Software Development Kit), allowing developers to write, test, and debug Android apps efficiently. Its built-in emulator lets developers test applications on virtual devices across different screen sizes and Android versions.
