1. Android Build Engineering @ Airbnb FELIPE LIMA / @FELIPECSL / NOV 10, 2016 / CODEPATH
2. Team scaling
3. • Tripled in 1 year • Migrated to a monorepo • More code, slower builds Team Scaling
4. React Native
5. React Native • Development Environment • Seamless build integration • Production crashes • Learning curve
6. Build Engineering
7. Build Engineering • Debug builds with 200K+ methods • Almost 10 min. clean builds • Poor parallelization • Multidex issues
8. Buck
9. • Mature: Created by and actively maintained by Facebook. • Speed: Focused on performance. Highly concurrent. • Caching: Aggressive caching, supports remote cache server. • Simple: Rely on small and self contained modules. Enter Buck A new hope for Android
10. Challenges • Caching: Hard to debug. Hidden changes invalidate cache keys. • Modularity: Obscure issues with annotation processors, harder to figure out code dependencies. • Configuration: Verbose, hard to parse and understand. • Dependency resolution: No automatic dependency download. Needs to be available locally. • Adoption: Requires many changes to the codebase.
11. Adoption • OkBuck: A lifesaver. Uses Gradle's project model to generate BUCK configuration files. • Traction: Recently being adopted by many companies like Airbnb, Uber and Lyft. • Supported Features: Most popular libraries supported (Retrolambda, ButterKnife, Sqldelight, etc).
