## What it is
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)
