I recently bought online courses on the android application, I installed everything, there were minor problems, but I solved everything, except for this one, I can’t find a solution how to fix it.

Answer 1

First, clear your caches.
If it does not help, then we will think further.

Answer 2

From the screenshots, it seems to me that this is not an android course, but a pure Java course.
It is better not to do it in the studio, but in IntelliJ IDEA
