Lint for Life: Your Customizable Guard On the Go
summary
Demonstrates a custom Android Lint rule that flags constructors with more than two parameters and suggests a generated builder, implemented with UAST/PSI scanners, IssueRegistry, and the Lint testing API; packaging uses a lint JAR or Gradle artifact and an environment variable controls the parameter threshold. Includes an autofix replace that inserts the builder in the IDE, tests pass, and the approach already shipped a Retrofit-related rule at Groupon. Notes that Android Lint grows to about 300 checks and integrates into build-time and IDE reports.
