@Override Error in Android Studio

Question

I'm new in Android Studio and Java. After I create any android projects, they have an error at first!

Error is for "@Override" When I hold mouse on it, it says "method does not override method from superclass"

What I should do to solve this error?

Thanks.

Answer 1

When you add @Override to a method, if

method does not override method from superclass

appears. It means IDE can't find the method with same signature in its super class.

From my view, I guess you didn't add the library which contains AppCompatActivity properly. Please have it examined.
