I have a configuration.xml file which I hold all the (yep, you guessed it!).. configuration strings and values and stuff.
One of those values is a string which is an oauth client id, and it has a hyphen..
Replace "-" with an "en dash" character (–, –) ?
You wrap your values in
which stops the parser from parsing the contents. E.g.
<string name="server_clientid"><![CDATA[ 5467656-blahblahblah.apps.googleusercontent.com ]]></string>
