Clean Code Base: Harnessing the Power of Android Lint and Custom Rules
summary
Android Lint plus a small custom-rule module catches real problems: it finds the intent-filter exported receiver issue that blocks Android 12 installs, detects mismatched translations that cause runtime crashes, and flags mutating SharedPreferences and allocations inside draw that hurt performance. Using the Gradle lint plugin, Google’s template repo, PSI/evaluator APIs and open-source rule sets (Slack/Uber), teams run lint on CI, produce a baseline file for legacy noise, and write JVM tests so rules unblock a target-SDK upgrade and fix dependency bugs.
