I am storing it in the XML as a way of storing the value... any other
standard conventions that are recommended? Store this as a static
constant in a static 'settings' class maybe?

I'm not counting on it returning anything useful, just having the
functionality indicate that it has finished is enough, I am then
setting a boolean field to true when it does, so that I know I that
the app has created a temporary copy of the file in the app's cache
directory. On exiting the program, if the field is true, I then empty
the cache directory. Obviously don't need to do this if I am no
longer copying the file if/when I get the method you suggest using
onFile() to work.
On that front, I have overriden the onFile() method in my content
provider, but it is not being triggered by the above code, any
suggestions?
@Override
public ParcelFileDescriptor openFile(Uri uri, String mode) {
Log.d(LOG_TAG, "openFile() called");
return null;
}
