2.8 Updating Android Studio and the SDK
From time to time new versions of Android Studio and the Android SDK are released. New versions of the SDK are installed using the Android SDK Manager. Android Studio will typically notify you when an update is ready to be installed.
To manually check for Android Studio updates, click on the Configure -> Check for Updates menu option within the Android Studio welcome screen, or use the Help -> Check for Updates... (Android Studio -> Check for Updates... on macOS) menu option accessible from within the Android Studio main window.
