What is androidx?

Artifacts within the androidx package comprise the libraries of Android Jetpack.

Libraries in the androidx package provide functionality that extends the capabilities of the Android platform. These libraries, which ship separately from the Android OS, focus on improving the experience of developing apps through broad OS- and device-level compatibility, high-level abstractions to simplify and unify platform features, and other new features that target developer pain points.

What happened to the Support Library?

As part of the Jetpack project to improve developer experience on Android, the Support Library team undertook a massive refactoring project. Over the course of 2017 and 2018, we streamlined and enforced consistency in our packaging, developed new policies around versioning and release, and developed tools to make it easy for developers to migrate.

Revision 28.0.0 of the Support Library, which launched as stable in September 2018, was the last feature release in the android.support package. There will be no further releases under Support Library packaging.
