Hi, I’m stuck on step 2-G. The app won’t even load and I get these errors:

error: failed linking references.

Does anybody know what’s wrong?

I haven’t done this project, but I’ve debugged a lot of Java. Check out this StackOverflow page: https://stackoverflow.com/questions/64833521/android-studio-4-1-1-resource-linking-failed

The guy’s problem looks about the same as yours.
