у меня естьActivity в котором у меня есть приватный класс Data. вonSaveInstanceState метод, я пытаюсь сохранить этот экземплярData. This is my whole Activity:

<code>public class TestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    public void onSaveInstanceState(Bundle outState){
        outState.putSerializable("TEST", new Data());
    }

    private class Data implements Serializable {

        private static final long serialVersionUID = -4312723541994925110L;

    }
}
</code>

Теперь, когда я меняю ориентацию устройства,Data Объект сохраняется и читается как следует. Тем не менее, когда я нажимаю кнопку «Домой», приложение аварийно завершает работу со следующим в logcat:

Когда я комментирую строку вonSaveInstanceState метод такData объектnot сохранено, приложение исчезает правильно.

Любая помощь с этим?
