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 may
offer variations to match your computer's processor architecture (such as
Intel x86 and ARM EABI). System images labeled Google APIs include
access to
Google Play services and those labeled Google Play also include
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 below 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.
Important: To see the most recent Android
system components in the Android SDK Manager, you must first update
SDK Tools to the most recent
release and restart the SDK Manager.
