Cannot inherit from final class

Question

I installed Android studio 0.4.2 at Windows 7(64-bit). Try create simple project from studio, but I get an error:

Cannot inherit from final class

Answer 1

In addition to the above answer and before deleting the files, i opened the project which is broken, Android Studio told me gradle is out dated, and there was a small URL in the message that says fix gradle... this did something, but did not quite solve my problem. Afterwards, i deleted the files above, and everything worked.
