StackOverFlowError lors de la création d'une activité héritée

Question

J'ai un CycleActivity abstrait qui étend l'activité. J'ai aussi quelques autres activités qui prolongent CycleActivity. Lorsque l'une des activités est créée que je reçois:

07-28 19:42:20.850: E/AndroidRuntime(21162): FATAL EXCEPTION: main 
07-28 19:42:20.850: E/AndroidRuntime(21162): java.lang.StackOverflowError

Quelle est la raison de ce comportement?

CycleActivity.java

protected void onCreate(Bundle savedInstanceState, 
     GameState finishAfterGameState, Class<?> nextActivityClass) 
{ 
    onCreate(savedInstanceState); 
    this.finishAfterGameState = finishAfterGameState; 
    this.nextActivityClass = nextActivityClass; 

    gameStateChangeHandler = new Timer(); 
    TimerTask gameStateChangeHandlerTask = new TimerTask() 
    { 
     @Override 
     public void run() 
     { 
      handleGameStateChange(); 
     } 
    }; 
    final int GameStateChangeHandlePeriod = 1000;// TODO: 
    gameStateChangeHandler.schedule(gameStateChangeHandlerTask, 0, 
      GameStateChangeHandlePeriod); 

} 

private void handleGameStateChange() 
{ 
    Game game = Game.getInstance(); 

    long finishesAt = 0; 

    GameState[] gameStates = GameState.values(); 
    for (GameState gameState : gameStates) 
    { 
     finishesAt += gameState.getDuration(); 
     if (gameState.equals(finishAfterGameState)) 
     { 
      break; 
     } 
    } 

    if (game.getGameTime() > finishesAt) 
    { 
     gameStateChangeHandler.cancel(); 

     runOnUiThread(new Runnable() 
     { 
      @Override

       finish();

    } 

} 

@Override

{ 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.result, menu);

    super.onCreate(savedInstanceState, GameState.Tour, ResultActivity.class); 
...

Vous avez une chose de référence circulaire se passe ici. Votre CycleActivity crée une GameActivity et vice versa, par conséquent vous n'avez plus de pile en raison de la récursion infinie.
