java/解析错误。正在尝试从android sdk发送到解析

几天前为另一个应用程序设置了这个，它运行良好，结果成功发送到MongoLab。 尝试使用下面相同的基本代码为新应用程序再次执行此操作，但每次都失败

有什么想法吗？谢谢

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

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

    // Add your initialization code here
    Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
            .applicationId("abc123")
            .clientKey(null)
            .server("http://abc123.herokuapp.com/parse/")
    .build()
    );

      ParseObject gameScore = new ParseObject("GameScore");
      gameScore.put("score", 1337);
      gameScore.put("playerName", "Sean Plott");
      gameScore.put("cheatMode", false);
      gameScore.saveInBackground(new SaveCallback() {
          public void done(ParseException e) {
              if (e == null) {
                  Log.i("Parse", "Save Succeeded");
              } else {
                  Log.i("Parse", "Save Failed");
              }
          }
      });
