title: Error "package android.support.v7.app does not exist"
body: <p>I am new to android development, and I have been using the command line tools to create an android project.  I followed all the instructions given in the <a href="http://developer.android.com/training/basics/firstapp/index.html">tutorial at android developers</a>.  However, they are focused more on IDE users.</p>
  
  <p>When I tried extending my MainActivity class from ActionBarActivity instead of just Activity, it threw the following error.</p>
  
  <p>error: package android.support.v7.app does not exist</p>
  
  <p>It was complaining about this import statement.</p>
  
  <pre><code>import android.support.v7.app.ActionBarActivity;
  </code></pre>
  
  <p>I made sure to visit the SDK manager, and it says Android Support Library is installed.
  I am truly stumped on this one, and I would really appreciate any help you guys could give me.</p>
  
  <p>This might help:
