I've been looking for posts in this forum related to this, one of them is Jetifier andorid (x) into an additional folder, cleaning project and I have done everything but it still has an error.

What should I do to get the application running

Thanks U Before

looks like you're missing androidx.print. how up-to-date is your sdk? launch it from the ide and type "androidx.print" in the search box. see if it says installed.
