I think you can see from your stack that you do not even get near your XML
parsing code.It is my impression that you fail open the Http connection to
get the file.
This might be because you have not given permission to your app to access
the internet.
Could you check that you have
<uses-permission android:name="android.permission.INTERNET" />
in your AndroidManifest.xml?
