SYNOPSIS

jetifier-standalone [options] -i input -o output

jetifier migrates Android libraries from Support Library to AndroidX. It rewrites bytecode and resources to use new package names.
The tool enables using older libraries with AndroidX projects. It processes AAR and JAR files automatically.

CAVEATS

Part of Android SDK. Forward migration (Support to AndroidX) is preferred. Some libraries may not be fully compatible. Jetifier is considered legacy as most libraries have migrated to AndroidX natively.

HISTORY

jetifier was created by Google to assist in the Android Support Library to AndroidX migration introduced in 2018.
