This sample shows how to construct a simple collection widget. This particular example shows how
to create a widget containing a <a href="../../../reference/android/widget/StackView.html"><code>StackView</code></a>
; however, only minimal changes are required to include
a <a href="../../../reference/android/widget/ListView.html"><code>ListView</code></a>,
<a href="../../../reference/android/widget/GridView.html"><code>GridView</code></a> or
<a href="../../../reference/android/widget/AdapterViewFlipper.html"><code>AdapterViewFlipper</code></a> instead.
</p>
<p>
The sample demonstrates the following:
</p>
<ul>
<li>
The pattern for creating and wiring a <a href="../../../reference/android/widget/RemoteViewsService.html"><code>RemoteViewsService</code></a>
and <a href="../../../reference/android/widget/RemoteViewsService.RemoteViewsFactory.html"><code>RemoteViewsFactory</code></a> which
serve the function of an adapter for the widget collection.
</li>
<li>
The pattern for setting an intent template and fill-in intents in order to
provide children of the collection with click behaviour.

<li>
How to make a widget with a <a href="../../../reference/android/widget/StackView.html"><code>StackView</code></a>

// from the network, etc., it is ok to do it here, synchronously. The widget will remain
// in its current state while work is being done here, so you don't need to worry about
// locking up the widget.
