Faster builds on Android: from 2 minutes to 2 seconds
summary
Claims concrete steps and measured wins: use Gradle Build Scans or the profile flag to see task timings, update Gradle/JVM/Android Studio, enable caching and parallel execution and Kotlin incremental compilation, and make a development build variant to skip resources. Modularize so modules compile in parallel and only what changes. Examples include reducing a full-app build from ~30s to ~21s, a library+app iteration from 65s to 9s, and unit tests in a pure JVM module running in 1–2 seconds.
