title: The import android.support cannot be resolved
body: <p>I am trying to run the code provided <a href="http://architects.dzone.com/articles/building-rss-reader-android" rel="noreferrer">HERE</a><br>
  I downloaded the code from their Github and imported into Android SDK, but it shows error at the lines  </p>
  
  <pre><code>import android.support.v4.app.FragmentActivity;
  import android.support.v4.app.NavUtils;  
  </code></pre>
  
  <p>in multiple files. However if I check the Android SDK Manager, the <code>Android Support Library</code> as well as the <code>Android Support Repository</code> in the Extras folder are both installed. I can also see the support folder and it's contents in the <code>SDK_INSTALL\sdk\extras\android\support</code> directory. It also has the v4 folder which also contains the <code>android-support-v4.jar</code> and the <code>src</code> folder. THen why is it still showing the error, how do I resolve it and how do I get that sample code running? THe sample code is for an RSS reader app, if that's relevant.</p>
