android .os.BadParcelableException: ClassNotFoundException при демаршалинге

Question

Мы сталкиваемся с получением исключения BadParceableException, и мы не знаем почему. Выше - трассировка стека:

Мы видели некоторые похожие ошибки здесь, в stackoverflow, но на самом деле никто не работал с нами.

Исключение составляет сообщение о том, что ошибка происходит в "super (in ) "в этом классе:

private stati c class SavedState extends BaseSavedState {int mSelectedPosition;

SavedState(Parcelable superState) {
    super(superState);
}

private SavedState(android.os.Parcel in) {
    super(in);
    this.mSelectedPosition = in.readInt();
}

@Override
public void writeToParcel(android.os.Parcel out, int flags) {
    super.writeToParcel(out, flags);
    out.writeInt(this.mSelectedPosition);
}

public static final Parcelable.Creator<SavedState> CREATOR =
        new Parcelable.Creator<SavedState>() {
            public SavedState createFromParcel(android.os.Parcel in) {
                return new SavedState(in);
            }

            public SavedState[] newArray(int size) {
                return new SavedState[size];
            }
        };

}

Есть ли у кого-нибудь идеи, чтобы нам помочь? ?

Спасибо!
