Improving Android Build Performance

on YouTube ↗40m

" summary

Shows concrete fixes and tools: use Gradle profiler to automate scenarios, upload results to build scans, and run Gradle 5.5 with Android Gradle Plugin 3.4.1 (3.5 incoming). Give the daemon more heap (example: 4 GB cuts GC from 20s to 5s, shaving ~12s), avoid configuration-time dependency resolution and costly settings scripts, enable configuration avoidance and task caching, remove changing inputs (Crashlytics build IDs), use incremental compilation/Kapt with Kotlin 1.3.30, and enable remote cache and parallel builds for big multi-module gains.
