How Facebook Built Facebook for Android
summary
Facebook replaces the monolithic Android build with Buck, a Java tool with Python build files and explicit build targets that form a DAG so only affected modules rebuild. A migration to many small modules yields over 500 buck files in the repo, preserves IDE integration via a buck project generator, and cuts full build time from 3m40s → 1m30s on day one; later parallel tests drop 20 minutes to 4 and plans include a daemon and remote artifact cache.
