Imagebutton Selector Xml File Not Found In Eclipse 3.6.1?

Having some trouble with an ImageButton with a Selector.xml as the drawable source, keep getting the following error when I switch to the Graphical Layout in Eclipse: Unable to res

Solution 1:

Try a lowercase s in selector. If that does not help, get rid of the PI line, which looks like:

<?xml version="1.0" encoding="utf-8"?>

It is complaining about that line, though I am not quite certain why.
