Could not find class 'org.apache.poi.poifs.filesystem.POIFSFileSystem' in Android
<p>I am getting the following error:</p>

<blockquote>
  <p>Could not find class 'org.apache.poi.poifs.filesystem.POIFSFileSystem'</p>
</blockquote>

<p>when the compiler reaches:</p>

<pre><code>POIFSFileSystem myFileSystem = new POIFSFileSystem(myInput);
</code></pre>

<p>I added <code>poi-3.8-beta5-20111217.jar</code> to the class path.</p>

<p>The same code worked fine but after updating android SDK it shows the error.</p>
