Adding Secondary Data With a SimpleAdapter - Author variable labeled "redundant, or not being used"

After following the video and getting to the end, when i run my app it isnt showing the secondary author info. In my code "KEY_AUTHOR" is grey everywhere it is used and marked as unused. I keep looking at my code and i cant find anything i have done wrong. Im thinking it might be the "simple_list_item_2" or maybe the fact im using android studio instead of eclipse? Anyone have any ideas?

Within the handleBlogResponse method...

String[] keys = { KEY_TITLE, KEY_AUTHOR };
                int[] ids = { android.R.id.text1, android.R.id.text2 };
                SimpleAdapter adapter = new SimpleAdapter(this, blogPosts,
                        android.R.layout.simple_list_item_2, keys, ids);

                setListAdapter(adapter);

This is the propper way to set texts 1 and 2 of the simple_list_item_2 adapter. :) Your IDE should have nothing to do with the error. I completed the project in Android Studio as well, and it worked fine. Though, if you figure out which section the error is in (try using breaks or debug mode?), it would help to see what you have typed up. :)
