In this code, 'notifyObserver()' method is marked as 'never used'.
What is the problem? It is called in main() method but the inspection doesn't disappear.

Try File | Invalidate Caches/Restart.. | Invalidate and Restart. If problem remains, provide a sample project where issue is reproducible and your File | Export Settings... jar attached.
I already tried it but nothing has changed.
This is my sample project link:
