Building a better codebase with Lint
summary
Shows how to build a custom lint rule module that registers an IssueRegistry, implements a resource XML detector that flags a V1→V2 style detector (uses getApplicableElements, appliesTo layout, visitElement), and supplies a two-step lintfix autofix (unset then set attribute). Includes unit tests with the lint testing lib, explains baseline-driven incremental fixes, notes lintfix fails on first run then passes after fixes, and points out Android ships >100 default checks.
