I'm currently developing an extension for App Inventor. And for this, I need to use the AndroidX library, but unfortunately, App Inventor still use the old support library. So, I was searching for it's (AndroidX) JAR/AAR version so that I can use it, but sadly, didn't found it anywhere. It'd be really nice if someone could help me with this. Thanks :)

According to your question here you find jar and aar file
