title: Safely remove an Android Activity
body: <p>We all know how easily and safely to create a new <code>Activity</code>. Now I want to know how to remove an <code>Activity</code> from my project safely.</p>
  
  <p>I've created some activity in my project and feel that they are now needless and I want to delete them. But if I delete manually these files:</p>
  
  <ol>
  <li><p>The activity's XML file in the <code>/layout</code> folder</p></li>
  <li><p>The activity's Java file in the <code>/src</code> folder</p></li>
  <li><p>The <code>&lt;activity&gt;&lt;/activity&gt;</code> portion from the manifest file</p></li>
  </ol>
  
  <p>Then,</p>
  
  <ul>
  <li>Will no other data related that activity stays in my project? What are those?</li>
  <li>Is there any simple removal procedure like creating an activity in Eclipse?</li>
  </ul>
