在解组时找不到onSaveInstanceState / Class中的bundle意图

Question

我在onSaveInstanceState上将意图存储在bundle中。 但是我在onCreate上的getParcelable时遇到了问题。 我得到了ClassNotFoundException。

如果我尝试单独使用MyParcel putParcelable，我不会得到Exception，但是如果我把它放在intent中并通过bundle传递它，并从getParcelable中获取bundle？我得到了例外。

拜托，帮助我。请...

这是我的代码。

@Override
protected void onSaveInstanceState(Bundle outState) {
    Intent intent = new Intent(getIntent());
    outState.putParcelable("SAVED_INTENT", intent);
    super.onSaveInstanceState(outState);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = new Intent();
    if (savedInstanceState != null && savedInstanceState.containsKey("SAVED_INTENT")) {
        intent = savedInstanceState.getParcelable("SAVED_INTENT");
        MyParcel mParcel = intent.getExtras().getParcelable("EXTRA_PARCEL");
    }
}

MyParcel.class

public class MyParcel implements Parcelable, Serializable{

    public String parcel_string;
    public List<MyUrl> my_url;

    public MyParcel(){
        my_url = new ArrayList<Url>();
    }

    public MyParcel(Parcel in){
        parcel_string = in.readString();
        my_url = new ArrayList<MyUrl>();
        in.readTypedList(my_url, MyUrl.CREATOR);
    }

    public static final Parcelable.Creator<MyParcel> CREATOR = new Parcelable.Creator<MyParcel>(){
        @Override
        public MyParcel createFromParcel(Parcel in) {
            return new MyParcel(in);
        }

        @Override
        public MyParcel[] newArray(int size) {
            return new MyParcel[size];
        }
    };


    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(parcel_string);
        dest.writeTypedList(my_url);
    }
}

MyUrl.class

public class MyUrl implements Parcelable, Serializable{
    public String name = null;
    public String content = null;

    public MyUrl() {
    }

    public MyUrl(Parcel in){
        name = in.readString();
        content = in.readString();
    }

    public static final Parcelable.Creator<MyUrl> CREATOR = new Parcelable.Creator<MyUrl>(){
        @Override
        public MyUrl createFromParcel(Parcel in) {
            return new MyUrl(in);
        }

        @Override
        public MyUrl[] newArray(int size) {
            return new MyUrl[size];
        }
    };

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeString(content);
    }
}

这是我的StackTrace。
