Didn't find class “androidx.core.app.CoreComponentFactory”

Question

I don\'t know what to do about the following errors, I\'ve searched the web but not found anything:

java.lang.ClassNotFoundException: Didn\'t find class \"an         


        

Answer 1

In my case, the code works on one of my teammates' machine. These steps made it work for me too:

1. Close project
2. Remove the project from the list in the welcome screen
3. Open the project again

This is a solution to another problem, that I also found here in SO. It's worth a try when Invalidate and Restart doesn't solve it for you.
