No.
When i want you to uncheck and recheck the library in the librarytab then i would have said it like this.

When i say ReDownload then i mean. Do the download of v4.0 again. The new download also contains a correct androidX artifact.
Use the files from the newdownload. Make sure to place all files from the download in your additional library folder.

REFRESH the librarylist after updated the files.
Clean your project and try again.
