Solution

Publish a branch with AndroidX dependencies. AS 3.2 has a 'Refactor to AndroidX' option.

@Vincent-Carrier Thanks for the suggestion. We've talked internally about AndroidX support. I'll put this on our 1.1 roadmap and keep you updated on the progress.

We've chosen not to include AndroidX in the latest CameraKit beta versions, at least for the time being. Adding AndroidX required that the end user including CameraKit also needed to include AndoridX in their application. So in an effort to keep CameraKit as widely usable as possible, we've left it out.

Thanks again for the suggestion!

Please update to use androidx dependencies. This library is the only thing preventing us from turning off jetifier. Or at least offer an androidx version.
