Parcelable protocol requires a Parcelable.Creator object called CREATOR (I do have CREATOR)


I am trying to pass Parcelable data from one intent to another and this is the error I am getting:

08-31 14:12:22.709: E/AndroidRuntime(9931): FATAL EXCEPTION: main
08-31 14:12:22.709: E/AndroidRuntime(9931): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.matejsoftware.cardscoretracker/com.matejsoftware.cardscoretracker.Igra}: android.os.BadParcelableException: Parcelable protocol requires a Parcelable.Creator object called  CREATOR on class com.matejsoftware.cardscoretracker.Novaigra$Player

The thing is: I do have Parcelable.Creator object. I'll post the whole Parcelable code below:

public class Player implements Parcelable{
    String name;
    int score;
    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(score);
    }

    public Player(Parcel source){
        score = source.readInt();
        name = source.readString();
    }

    public Player(int score, String name){
        this.score = score;
        this.name = name;
    }
}

public class MyCreator implements Parcelable.Creator<Player> {

    @Override
    public Player createFromParcel(Parcel source) {
        return new Player(source);
    }

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

}

Is there somethin wrong with the CREATOR? The app crashes as soon as I click the button to start the next activity.

This is how I "retrieve" Parcelable data in the second activity:

//global variable
ArrayList<Player> playersParceledData;

//This is in onCreate
playersData = getIntent();
playersParceledData = playersData.getParcelableArrayListExtra("parceledData");

Also, this is how I put class objects to ParcelableArrayListExtra:

Player newPlayer = new Player(0, text);
playersParceledData.add(newPlayer);
zacniIgro.putParcelableArrayListExtra("parceledData", playersParceledData);

Solution

  • You are have different sequence when reading from Parcel than the one you write in.

    In writeToParcel() you are first putting String but in the HeatFriendDetail(Parcel in), you first read integer. It is not the correct way because the order or read/write matters.

    Following is the code which makes correct order when writing/reading the data to/from Parcel (also see this link):

    public class FriendDetail implements Parcelable {
    
        private String full_name;
        private int privacy;
    
        public HeatFriendDetail(Parcel in) {
            this.full_name = in.readString();
            this.privacy = in.readInt();
        }
    
        public HeatFriendDetail() {
    
        }
    
        @Override
        public void writeToParcel(Parcel dest, int flags) {
    
            dest.writeString(this.full_name);
            dest.writeInt(this.privacy);
        }
    
        public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
            public HeatFriendDetail createFromParcel(Parcel in) {
                return new HeatFriendDetail(in);
            }
    
            public HeatFriendDetail[] newArray(int size) {
                return new HeatFriendDetail[size];
            }
        };
    
        // GETTER SETTER//
    }
