This page provides release information about the SDK packages available for download from the SDK Manager, in the SDK Platforms tab.
Each SDK Platform version includes the following packages:
- The Android SDK Platform package. This is required to compile your app for that version.
Several System Image packages. At least one of these is required to run that version on the Android Emulator.
Each platform version includes a system image for each supported form factor (handsets, Android TV, and Android Wear). Each form factor might offer variations to match your computer's processor architecture (such as x86_64 and ARM 64 v8a). System images labeled Google APIs include access to Google Play services and those labeled Google Play also include the Google Play Store.
The Sources for Android package. This includes the source files for the platform. Android Studio may show lines of code from these files while you debug your app.
The revision numbers listed in the following sections are for the Android SDK Platform package only. The system images may receive separate updates, usually to resolve bugs with the emulator. There are no release notes for the system images, but you should always keep them up to date.

- Android 12 ATD system images
This Automated Test Device (ATD) image is an Android system image that is optimized for headless automated tests. Early data indicates that tests that use this image should experience reduction in emulator process CPU and memory usage, and reduction in test wall time.
It achieves these performance gains through:
- Removing most user-facing applications (for example Dialer, Settings, and SystemUI).
- Disabling hardware renderer drawing.
The image comes with two versions: Google APIs ATD which provides Google APIs, and AOSP ATD which provides pure AOSP experience.
To learn more about running tests using ATDs, see Run tests using Automated Test Devices.
