Android Build a Self-Destructing Message Android App Relating Users in Parse.com Executing a Query

I don't understand what I'm being asked to do?

I even tried referencing the code we had written during the lesson and I so much is omitted from the CodeChallenge.java code for brevity that I can't even sort out where within my code I should search. Maybe I need a break.....

Challenge Task 1 of 2: Let's continue with our previous code challenge. Execute the query that we built before using the findInBackground() method. Pass in the mFindCallback variable defined below.

CodeChallenge.java
// This code is an excerpt from an Activity. Some code has been omitted!

FindCallback<ParseUser> mFindCallback = new FindCallback<ParseUser>() {
    @Override
    public void done(List<ParseUser> users, ParseException e) {
        if (e == null) {

        }
    }
};

ParseQuery<ParseUser> query = ParseUser.getQuery();
query.orderByAscending("email");

Try this and see if it works:

query.findInBackground(mFindCallBack);
