Parse.com retrieve Ошибка ParseObject

Я использую Parse.com и загрузил небольшой 1kb json-файл для хранения своих данных. Теперь я хочу, чтобы загрузить его из Parse.com и заполнить его в ListView, но я уже не в состоянии с извлекая файл вот мой код:Parse.com retrieve Ошибка ParseObject

public class MainActivity extends AppCompatActivity { 
public static final String TAG = MainActivity.class.getSimpleName(); 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
Parse.initialize(this); 

    ParseQuery<ParseObject> query = ParseQuery.getQuery("testfile"); 
    query.getInBackground("VaCCc2YCp3", new GetCallback<ParseObject>() { 
     public void done(ParseObject object, ParseException e) { 
      if (e == null) { 
       Log.v(TAG, "SUCCESS"); 
      } else { 
       Log.v(TAG, "FAILURE"); 
      } 
     } 
    }); 
}}

Так, к сожалению, мой Logcat показывает мне:

V/MainActivity: FAILURE

Кажется простым, но что мне не хватает?

убедитесь, что вы называете Parse.initialize –

это действительно не хватало, однако я до сих пор ошибка – wjwj

предоставить больше кода, пожалуйста, и убедитесь, что вы используете правильную ссылку на объект , напечатать, почему он сбой вместо FAILURE e.getMessage() –

это, кажется, вы не хватает многих вещей, позвольте мне предоставить образец кода

public class StarterApplication extends Application { 

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

    // Enable Local Datastore. 
    Parse.enableLocalDatastore(this); 

    // Add your initialization code here 
    Parse.initialize(this); 

    ParseUser.enableAutomaticUser(); 
    ParseACL defaultACL = new ParseACL(); 
    // Optionally enable public read access. 
    // defaultACL.setPublicReadAccess(true); 
    ParseACL.setDefaultACL(defaultACL, true); 
    }

и в onCreate

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    ParseAnalytics.trackAppOpenedInBackground(getIntent()); 
    }
