title: ActionBarActivity cannot resolve a symbol
body: <p>In my android Studio, Compiler is not able to locate <code>ActionBarActivity</code>. Because of it, I am getting many errors. The compiler is not able to import the <code>ActionBarActivity</code> and <code>ActionBar</code> class. 
  These are the lines where compiler is throwing error:</p>
  
  <pre><code>import android.support.v7.app.ActionBarActivity;
  import android.support.v7.app.ActionBar;
  </code></pre>
  
  <p>I tried to search on stackoverflow before asking a question. The answer i got is for the eclipse which is to add the library. I tried doing it in Android Studio, but didn't get anything.</p>
