Question

It’s the usual activity. The problem is in onCreateOptionMenu. When I click the menu button nothing is done. I don’t see where the problem is.

I also try to comment all code without menu but It’s still don’t work.
It is either a very strange problem or I don’t see some simple things..

    private void copyFile(String filename) {

        }

    }

}

Help if you see a solution.

Answer 1

You’ve misspelled method name – it should be onCreateOptionsMenu(), not onCreateOptionMenu().
It’s preferable to use @Override annotation to avoid such mistakes:

@Override   
public boolean onCreateOptionsMenu(Menu menu) {

This way it will give you compile time error if you misspell method name or use wrong parameters.
