com.parse.ParseRequest $ ParseRequestException：缺少用户密码

这是我的应用程序类

public class ParseApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        // Register Subclass
        ParseObject.registerSubclass(One.class);
        ParseObject.registerSubclass(Two.class);

        Parse.enableLocalDatastore(this);

        Parse.initialize(this, "app_key", "client_key");

        ParseUser.enableAutomaticUser();

        ParseACL defaultACL = new ParseACL();
        defaultACL.setPublicReadAccess(true);
        ParseACL.setDefaultACL(defaultACL, true);

        ParsePush.subscribeInBackground("Testing", new SaveCallback() {
            @Override
            public void done(ParseException e) {
                if(e==null)
                    System.out.println("Subscribed Successfully");
                else
                e.printStackTrace();
                    System.out.println("Unable to Subscribe");
            }
        });

        //To save the current device on Parse Installation
        ParseInstallation.getCurrentInstallation().saveInBackground();
    }
}
