Extension SDK allows older versions of Android to use new features.
Extension SDK is mostly aimed at developers.
Google has been working on a way to bring updates to core components of Android through the Play Store for years. Its latest attempt at that is releasing a public version of its Extension Software Developer Kit to bring new features to older versions of Android.
According to XDA Developers, Google has made its Extension SDK available to the public. With it, versions of Android 11 and 12 should be able to use newer features that were exclusive to Android 13, like the OS’s new photo picker API.
