What's new in the Android Studio build system
summary
Build system work adds concrete wins: a new workers API converts ~90% of plugin tasks to side‑effect‑free work items to boost parallelism, artifact transforms gain caching and earlier scheduling for a 15% faster clean build on a 100‑module test, lazy task configuration cuts configured tasks from ~19,000 to ~3,000, incremental annotation processing and KAPT support reduce rebuilds, benchmarks show 50–80% faster for large projects and average 35% improvement, Instant‑style apply changes targets Android 8+, and a Chrome trace JSON profiler helps pinpoint slow tasks.
