20 Nuggets in 20 Minutes - Get more from your CI
summary
Twenty concrete CI tactics delivered as quick wins: integrate ChatGPT PR comments to summarize and review code, prefer modular Gradle graphs so 16-core machines beat 4-core by ~3x, leverage Gradle build cache hits to shave specific task times (example saved ~20s by fixing a signing file), publish live HTML annotations and APK size reports (Spotify Ruler), enforce module depth with graph-assert, cache Docker build layers, run CI locally via CLI, SSH into builds, publish OTA install pages, use Google Play REST API, and track flaky test rate by commit hash.
