title: Where can I find FragmentTabHost Library
body: <p>Ok, so this is what I get to see when I'm missing the library:</p>
  
  <pre><code>import android.support.v4.app.FragmentTabHost;
  </code></pre>
  
  <p>Where can I find it and how do I need to add this library to my project?</p>
  
  <p>Any help is appreciated.</p>
