What does it say if you hover over the @Override?

Okay! Thanks for your time and also I understand about the late responses (It's the same with me, I have school too!).

When extending Activity, you have no need to override the getPageTitle() method since you aren't overriding or implementing something to the method.

Basically, @Override will overwrite the method in the parent class so, the code that deals with getting the page title will not run. Java is giving you an error here because this method can not be overwritten (This is mainly a safeguard to prevent things going wrong in your code as a result).

I hope this explains it but, if you have any more questions, give me a shout! :)

So remove the override?

Yes :)

I thought I'd also include a bit of an explanation about why you got that error as well as, it's useless if I give you an answer without explaining it!

The concept of overrides can seem confusing at first but, there are plenty of comments on the internet that explain how they function.
