action bar navigation for extra credit

I'm trying to do the extra credit by setting up the action bar navigation for "where's my up button?" I'm trying to do it like this as google says:

ActionBar actionBar = getSupportActionBar(); actionBar.setDisplayHomeAsUpEnabled(true);

but getSupportActionBar doesn't work. Further information said that I need the class in BlogWebViewActivity to extend ActionBarActivity rather than just Activity. But if I change that then the entire project becomes one giant error. I also need to create the appcompat_7 library to import.

How do I go about adding this?

Did you try this:

ActionBar actionBar = getActionBar(); actionBar.setDisplayHomeAsUpEnabled(true);

I know in the apps i have created that I used this to get the actionBar. Not sure if it will work but it is just a suggestion.

It did work, thank you. From what I understand now, SupportActionBar is only for older versions (v7 or below) of android SDK
