AndroidX (formerly known as Android Support) libraries have moved

frameworks/support is no longer part of the platform checkout. Android platform now uses prebuilts of AndroidX for everything. AndroidX is being developed as an unbundled project.

Next steps

• For source-code for your IDE, please use *-sources.jars in prebuilts/sdk/current/androidx
• To contribute, check out the AOSP (onboarding guide).
• For internal contributions dependent on pre-release platforms, see go/androidx-dev.
