" summary

Step-by-step guide to writing and testing custom Android Lint checks using the AGP3-era toolchain: creates a Hungarian-notation detector that flags m/S prefixes, compiles a lint.jar and registry, and runs unit tests with the JUnit4 fluent API; explains UAST/PSI parsing and detector scopes so checks run on Java and soon Kotlin; shows a Gradle snapshot checker that scans dependency coordinates, handles duplicate reports, and bundles lint jars into AARs; demos quick fixes that modify source (string truncation for tag length) and verifies them with expect-fix diffs.
