Cannot resolve symbol AppCompatActivity - Support v7 libraries aren't recognized?

Question

I\'m trying to figure out why the heck my Android studio isn\'t recognizing the AppCompat v7 library correctly. The import statement below shows up as gray and says there\'s

Answer 1

I changed from "... extends ActionBarActivity" to "... extends AppCompatActivity" and tried cleaning, restarting, Invalidate Caches / Restart and wasn't getting anywhere. All my versions were up to the latest.

What finally solved it was making sure my import was correct:

import android.support.v7.app.AppCompatActivity;

For some reason it didn't get set up automatically like I was used to and I had to add it manually.

Hope that helps someone!
