title: The meaning of @android
body: <p>I would like to ask what is the meaning of <code>@android</code> as in <code>android:id="@android:id/list</code>.  I have seen it in different android samples and tutorials, and I have also googled it.  The only explanation I found is "The list and empty IDs are provided for us by the Android platform, so, we must prefix the id with android:" from <a href="http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html" rel="nofollow">http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html</a></p>
  
  <p>Thank you.</p>
