android method is undefined prob
<p>I am using the CameraDemo code and have added some extra functionality to it.  I have calls to <code>getFilesDir()</code> and <code>openFileInputString()</code> in both <code>CameraDemo.java</code> and <code>Preview.java</code>.  The Problem is window won't let me run because it says that both these are undefined for the type Preview.  Running 'clear project' doesn't help. It doesn't object to them in CameraDemo and I've checked the imports and I now have all the ones in CameraDemo also in Preview.   The android help seems to indicate they both are in Class File  and I have <code>import java.io.File</code> in both files.  I hope someone has a suggestion!
Thanks</p>
