Android : savedInstanceState.getParcelableArrayList() return empty list

If screen is rotated, I want to save list of My objects, so I implemented my Object as following:

public class Video implements Serializable, Parcelable {

private String mTitle;
private String mVideoID;
private String mThumbUrl;

public Video(String title, String id, String thumbUrl) {
this.mTitle = title;
this.mVideoID = id;
this.mThumbUrl = thumbUrl;
  }

 @Override
public int describeContents() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    // TODO Auto-generated method stub
    dest.writeString(mTitle);
    dest.writeString(mVideoID);
    dest.writeString(mThumbUrl);
}

public Video(Parcel in) {
    // TODO Auto-generated constructor stub
    mTitle = in.readString();
    mVideoID = in.readString();
    mThumbUrl = in.readString();
}

public static final Parcelable.Creator<Video> CREATOR = new Parcelable.Creator<Video>() {

    @Override
    public Video[] newArray(int size) {
        // TODO Auto-generated method stub
        return new Video[size];
    }

    @Override
    public Video createFromParcel(Parcel in) {
        // TODO Auto-generated method stub
        Log.e("CREATOR", in.readString());
        return new Video(in);
    }
};

}

And in the MainActivity, i retrieved saved list of objects:

  if (savedInstanceState != null) {
        ArrayList<Video> saved = savedInstanceState.getParcelableArrayList(VIDEO_LIST);

        Toast.makeText(this, "Count: " + saved.size(), Toast.LENGTH_SHORT)
                .show();
    }

--> The problem is, After rotating screen list of objects is empty: saved.size() = 0 Please tell me why? I how can i resolve it. Thanks
