URI Scheme definition?
<p>I'm working off this tutorial: <a href="http://www.developer.com/ws/article.php/10927_3833306_2/Creating-a-Home-Screen-App-Widget-on-Android.htm" rel="nofollow">http://www.developer.com/ws/article.php/10927_3833306_2/Creating-a-Home-Screen-App-Widget-on-Android.htm</a></p>

<p>It includes the following code:</p>

<pre><code>   widgetUpdate.setData(
   Uri.withAppendedPath(Uri.parse(
   ImagesWidgetProvider.URI_SCHEME + "://widget/id/"), 
   String.valueOf(appWidgetId)));
</code></pre>

<p>My question is, what should URI_SCHEME be defined as and where?</p>
