## What it is
The AOSP Android Support Library (the predecessor to AndroidX/Jetpack), a set of Java libraries providing backward-compatible UI components and APIs for Android app development. This mirror repository primarily serves as the contribution and development source for the support library codebase.

## Use cases
- build android apps that run on older api levels
- contribute bug fixes to the android support library
- debug support library behavior with demo apps
- run support library tests locally
- backport newer android ui features to older devices

## When to choose
- you need to fix or patch the legacy android support library itself
- you maintain an older android app still built on the support library
- you want to study the source of android's backward-compatibility libraries

## When to avoid
- you are starting a new android project - use AndroidX/Jetpack libraries instead
- you want to add new features or modules - contributions of new functionality are not accepted
- you develop on Windows - building is only supported on Linux and macOS

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, developer-tools, testing
- domain: mobile-development, developer-tools, cross-platform
- platform: jvm
- tags: android, androidx, support-library, aosp, jetpack, mobile, contribution-guide
