I'm new to Android, and i've got some issues. It looks like it's saying that's having an null object passed to it, but I'm not sure. Where I missed a step? Any help is appreciated.

Thanks in advance.

In line 138 you create a new instance of EmployeeOperations, but never call its open() method (which presumably calls DatabaseHelper#getWritableDatabase()), so the instance's reference to the database does not get initialized, and is null when it is used in the next line.
