I am writing a game that has a save function which looks like this 

    public void Save()
    {

        System.Xml.Serialization.XmlSerializer ser = new System.Xml.Serialization.XmlSerializer(this.GetType());
        System.IO.StreamWriter file = new System.IO.StreamWriter(("Assets/Resources/Save");
         ser.Serialize(file, this);
        file.Close();
    }
}

This will work fine in the editor and on Windows machines, but when we build to Android the saving no longer works. Why is that?

No longer works in what way? Are you getting an error? –  Byte56♦ Dec 19 '13 at 22:39
    
From session to session with the game you cannot have a save load, it reverts back to if a there was no save file. –  Tucker Morgan Dec 19 '13 at 22:40
    
"From session to session with the game you cannot have a save load", well yes, if the file isn't writing, you couldn't load it. "it reverts back to if a there was no save file"... huh? –  Byte56♦ Dec 19 '13 at 22:45
    
I have a system where it checks to see if there is a save file, if not it loads so other data a creates a new save file. So it is not saving every time you start the game it creates a new save file. My problem is that it cannot find the XML file to save to. –  Tucker Morgan Dec 19 '13 at 22:49

It's likely to do with the path you're trying to save to and/or the permissions. While I haven't done this myself, all the examples I've seen where people are writing to files in Android, they have to use Application.persistentDataPath and append their directory to the end. This ensures you're writing to the correct location, and a location where you have permission to do so.
