Android : How to retrieve the value of a pointer column from parse

I want to retrieve the value stored in a pointer type column in parse. I am using the following:

ParseQuery test = ParseUser.getQuery();
                test.include("_Installation"); 
                test.getInBackground("EMqw4TOQ0c", new GetCallback() {
                    public void done(ParseObject parseObject, ParseException e) {
                        id = parseObject.get("identification").toString();
                        Log.d("SUCCESS !!! :",id);
                    }
                });

With this I get com.parse.ParseInstallation@42619a80 the value of the id which is wrong.

How can I get the correct value stored?
