title: Issues with Android TabHost Example
body: <p>I have been attempting to implement the 'advanced' <a href="http://developer.android.com/resources/tutorials/views/hello-tabwidget.html" rel="nofollow noreferrer">tabwidget</a> example from google.  But, when it tries to call <code>tabHost.addTab(spec);</code> I get a stack trace from the debugger.  Sorry, I don't have the stack trace here, but I'm wondering if others have had this same issue (as this code had a number of typo's and missing information that stopped me from even compiling.</p>
  
  <p>Can anyone point me to a corrected/running version of this code?</p>
  
  <p>The updated information needed are:</p>
  
  <pre><code>&lt;activity android:name=".ArtistsActivity"&gt;&lt;/activity&gt;
  &lt;activity android:name=".AlbumsActivity"&gt;&lt;/activity&gt;
  &lt;activity android:name=".SongsActivity"&gt;&lt;/activity&gt;
  </code></pre>
