AndroidX Versions

AndroidX libraries ship separately from the Android OS, so updates to the libraries can happen independently and more frequently.

AndroidX uses strict semantic versioning. A version string (like 1.0.1-beta02) contains three numbers representing major, minor, and bugfix levels. Pre-release versions also have a suffix that specifies the pre-release stage (alpha, beta, release candidate) and revision number (01, 02, and so on).

Every version of a library moves through three pre-release stages on its way to becoming a stable release. The critieria for each pre-release stage is:

Alpha

  • Alpha releases are functionally stable, but may not be feature-complete.
  • While a release is in alpha, APIs may be added, removed, or changed.

Beta

  • Beta releases are functionally stable and have a feature-complete API surface.
  • They are ready for production use but may contain bugs.
  • A beta release cannot use experimental compiler features (such as @UseExperimental).
  • Dependencies on other libraries must be beta, rc, or stable versions. No alpha dependencies are allowed.

Release Candidate (RC)

  • A release candidate is a prospective stable release.
  • It may contain critical last-minute fixes.
  • Its API surface is final.
  • Dependencies on other libraries must be rc or stable versions only.

A library can have multiple versions at the same time. Each version has a different release stage. For example, while the stable release of androidx.activity could be 1.0.0, there might also be a 1.1.0-beta02 release as well as a 2.0.0-alpha01 release.

Use this page to learn of the latest updates to the libraries.

The AndroidX release notes overview page lists the libraries that have recently changed. Google's Maven repository shows the complete version history.

Use the table below to view the most recent stable and preview versions of every AndroidX library. The links on each row take you to the library's release notes. In the release notes you'll find:

  • The chronological history of all the releases.
  • A code snippet with the default gradle dependency declarations to use the artifacts.
  • Links to the Kotlin and Java reference pages for the packages in each artifact.
