fastdex is a Gradle plugin and Android Studio plugin that speeds up Android APK build times by caching pre-built dex files and only recompiling changed project code. It also pushes incremental dex and resource patches to a running app via adb to skip reinstall time.

Use cases

• speed up slow apk builds with multidex
• reduce android gradle build time
• avoid full dex generation on every assemble
• push incremental dex patches to a running app without reinstalling
• replace instant run for faster debug iterations

When to choose

• your Android project has multiple dex files and slow transformClassesWithDex builds
• you want faster incremental debug builds on older Android gradle plugin versions
• you want to hot-push patches to a running debug app

When to avoid

• building production release apks (builds are debug-only, code placed in secondary dex slows pre-5.0 devices)
• your buildType enables obfuscation (ignored by fastdex)
• you use modern Android Gradle Plugin versions or need maintained tooling (last release 2018)
