Improving Android Build performance

on YouTube ↗30m

" summary

Typical installs see huge wins by measuring first: use Gradle Profiler to script repeatable scenarios and build scans to find the exact task that regresses. Upgrading to recent Gradle and the Android plugin plus a healthy daemon cuts GC stalls (example: 17s GC = 8% of build time). KAPT can add tens of seconds (a Kotlin AP example: clean 30s → +50s with KAPT), enabling incremental annotation processing (Gradle 4.7 opt‑in) and using the build cache / remote cache and parallel execution often reduces team build time by orders of magnitude.
