Fragmentation has been a longstanding complaint about the Android ecosystem. Often users miss out on features of the latest Android version because they are using older devices that are no longer updated. To reduce the gap, Google has released the first public version of the Extension SDK, which aims to bring features of the latest Android version to older iterations.

As a part of this announcement, Google is opening up Photo Picker API support to Android 11 and Android 12. Photo picker lets users give access to select photos from their library to an app — right now, only Android 13 users can use the latest photo picker interface.
