Firebaseにオブジェクトのリストを追加する

「ゲーム」オブジェクトをFirebaseデータベースに入れるコードに取り組んでいます。各ゲームには名前と「プレイヤー」という名前のアーリーリストがあり、それぞれに名前と「ターゲット」があります。しかし、私はコードを実行すると、アプリケーションがクラッシュするだけで明確なエラーは、それだけでメソッドを実行することができないと述べています。私はそれがゲームの名前だけで動作するようになる以前に、プレイヤーのリストと関係があると確信しています。Firebaseにオブジェクトのリストを追加する

Games: 
    Game1: 
     name: Johns Game 
     Players: 
      John 
      Mike 

    Game2:......

EDIT 1 プレイヤーがプレイヤー名を尋ねるダイアログで初期化し、その後にプレイヤーを渡している：私のような組織化私のデータベースをしたい明確にすることが

public void beginGame(View view) { 
    mDatabase = FirebaseDatabase.getInstance().getReference(); 


    EditText gameNameField = (EditText) findViewById(R.id.gameName); 
    String gameName = gameNameField.getText().toString().trim(); 
    Collections.shuffle(players); 
    if (gameName.isEmpty()) { 
     int duration = Toast.LENGTH_LONG; 

     Toast toast = Toast.makeText(getApplicationContext(), 
       R.string.toast_no_game_name, duration); 
     toast.show(); 

    } else if (playerNames.size() < 2) { 
     int duration = Toast.LENGTH_LONG; 

     Toast toast = Toast.makeText(getApplicationContext(), 
       R.string.toast_not_enough_players, duration); 
     toast.show(); 

    } else { 
     for (int i = 0; i < players.size(); i++) { 
      if (i != (players.size() - 1)) { 
       players.get(i).target = players.get(i + 1); 
      } else { 
       players.get(i).target = players.get(0); 
      } 
     } 
     Game game = new Game(gameName, players); 
     mDatabase.child("Games").child(gameName).setValue(game); 

     Intent intent = new Intent(StartNewGameActivity.this, SessionsActivity.class); 
     startActivity(intent); 
    } 
}

配列リスト

public void addNewPlayer(View view) { 
    DialogFragment newFragment = new CreatePlayerDialogFragment(); 
    newFragment.show(getSupportFragmentManager(), "Player"); 
} 

@Override 
public void onDialogPositiveClick(String name) { 
    playerNames.add(name); 
    players.add(new Player(name)); 
}

そして、ここで私のLogcat

で同様の疑問を持っていますプレーヤーはどこで初期化されますか？また、あなたのLogcatにも正確にありますか？ – rhari

だから私は、正確なプレーヤーのコンストラクタを持っていませんでし（それが実際の名前に取るdidntの）が、場合には、私のコードを掲示イムは、あなたが部分を投稿することができ、将来の

からのエラーは私の知る限りでは、あなたは一人の子供の下で多くの値を持つことはできませんされています。新しいプレーヤーごとに新しい子を作成するたびに、値を1つずつ設定してみてください。 mDatabase.child（ "Games"）。子（gameName）.child（playerName）; playerNameが変更され（i ++は配列リスト内でインクリメントされます）、新しい子が各項目に対して作成されます。結局のところとして
