Answer 3

A folder and its subfile. I have tested this:

com.xx.xx.* { *; }   

I guess that it may contain multiply folders and subfile. I've not tested this:

com.xx.xx.**.* {*;}

Check this issue: https://issuetracker.google.com/issues/147802433

`If you right-click on error, there is option "suppress for statement", after that AS adds a comment such as:

noinspection ShrinkerUnresolvedReference

-keep class not.existing

And with this comment there is no error for "not.existing".`
