stage 4 task 1

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");
query.findInBackground(new FindCallback<ParseUser>());
