GridView Tutorial Fails To Compile
<p>I am trying to implement the GridView tutorial at:</p>

<pre><code>http://developer.android.com/resources/tutorials/views/hello-gridview.html
</code></pre>

<p>However, I get the error:</p>

<blockquote>
  <p>ImageAdapter cannot be resolved to a type.</p>
</blockquote>

<p>I am using Android 4.0 (API Level 4).</p>

<p>Googling for ImageAdapter does not find an official API description for it.</p>
