Android Lint
============

Android Lint is a static analysis tool (which despite the name is not
limited to Android, and within Google for example is used to analyze
Java and Kotlin server side code as well as Android and even desktop
software like IDEs.)

Lint's focus is on finding bugs (whether they are related to
correctness, performance, security, internationalization, usability and
so on); it's not a source code style checker.

Documentation History:
* June 2022: Added documentation for [crafting error
  messages](messages.md.html)
* May 2022: Noticed that the document rendering
  was broken, such that many chapters were missing from
  the api-guide: “Adding Quickfixes”, “Partial Analysis”,
  “Data Flow Analyzer”, “Annotations”, and “Options”.
  These are now included.
* November 2021: Added documentation for [option
  handling](api-guide/options.md.html)
* September 2021: Added documentation for [annotation
  handling](api-guide/annotations.md.html)
* July 2021: Added documentation for
  [test modes](api-guide/test-modes.md.html)
* June 2021: Added documentation for the
  [dataflow analyzer](api-guide/dataflow-analyzer.md.html),
  [Lint Gradle DSL](usage/agp-dsl.md.html) and
  [command line flags](usage/flags.md.html).
* May 2021: Added documentation for individual lint issues
