CI/CD for Android ROMs: Lessons from PixysOS

Building a reliable build pipeline for a community Android ROM, from scratch.

Building custom Android ROMs at scale means juggling dozens of device trees, kernel branches, and manifest changes every week.

We built a pipeline that triggered device-specific builds only when relevant trees changed, cutting average build time by more than half.

The Telegram and GitHub integrations turned the build bot into the team’s de facto status board — no one had to ask "did my build pass?" anymore.
