title: Android - application hasCode tag
body: <p>Android developer <a href="http://developer.android.com/guide/topics/manifest/application-element.html#code" rel="nofollow">page</a> for  <code>&lt;application&gt;</code> contains the flag <code>hasCode</code>. Its description says:</p>
  
  <pre><code>An application would not have any code of its own only if it's using 
  nothing but built-in component classes, such as an activity that uses 
  the AliasActivity class, a rare occurrence.
  </code></pre>
  
  <p>Can someone please give a code example of the AliasActivity use case (rare occurence) they talk about ?</p>
