What is the "icon" attribute in <provider> used for?
<p>I'm writing a content provider, it will be part of my application. What does the "icon" attribute in the  element do though?:</p>

<p><a href="http://developer.android.com/guide/topics/manifest/provider-element.html" rel="nofollow">http://developer.android.com/guide/topics/manifest/provider-element.html</a></p>

<p>Where would anyone ever see this icon? Is there a way for users to list all the content providers in the system, and they might see it in this listview perhaps?</p>
