## What it is
An official Google sample project demonstrating how to write, test, and package custom Android Lint rules in Kotlin/Java. It includes example lint checks, their tests, and documentation on distributing rules via lint.jar inside AAR libraries.

## Use cases
- write custom android lint rules
- how to create custom lint checks for android library
- test custom lint checks
- package lint rules in an aar
- enforce company-specific code rules with lint
- learn the android lint api

## When to choose
- you are an Android library author wanting to ship lint rules with your library
- you need to enforce team- or company-specific coding rules in Android projects
- you want a working reference for the Android Lint API and its testing setup

## When to avoid
- you need a production lint library rather than a sample to copy from
- you want static analysis for non-JVM languages
- you need a stable API - the lint API is explicitly not final and changes between releases

## Facets
- artifact type: learning-resource
- maturity: active
- function: testing, linter, developer-tools
- domain: android-tools, developer-tools, testing, tutorials
- platform: jvm, cli
- tags: android-lint, static-analysis, custom-lint-rules, sample-project, kotlin, android
