Putting Kotlin Parcelable Data Class in java bundle doesn't work

Question

I'm working with an Android Project where i use both Java and Kotlin together, I have a Kotlin Data Class with Parcelable implemented (Some properties in this class are custom Java POJO Class and it's Parcelable implemented too).

When I try to pass this class as an Intent Parcelable Extra in compile-time there are no errors, but when I try to retrieve this class in another Activity from Intent.getExtras().getParcelable("Key") it throws an exception

E/Parcel: Class not found when unmarshalling: 
    java.lang.ClassNotFoundException

So I tried to search for the cause of the exception and tried all the Answers in this question and nothing worked

1 - Koltin data class

data class OrderResponse (
    @SerializedName("client")
    var client: RideResponse? = null,

    @SerializedName("driver")
    var driver: BigRideResponse? = null,

    @SerializedName("id")
    var id: String? = null,
    @SerializedName("rideInfo")
    var rideInfo: RideDetails? = null
) : Parcelable {
    constructor(parcel: Parcel) : this(
            parcel.readParcelable(RideResponse::class.java.classLoader),
            parcel.readParcelable(BigRideResponse::class.java.classLoader),
            parcel.readString(),
            parcel.readParcelable(RideDetails::class.java.classLoader)) {
    }

    override fun writeToParcel(parcel: Parcel, flags: Int) {
        parcel.writeParcelable(client, flags)
        parcel.writeParcelable(driver, flags)
        parcel.writeString(id)
        parcel.writeParcelable(rideInfo, flags)
    }

    override fun describeContents(): Int {
        return 0
    }

    companion object CREATOR : Parcelable.Creator<OrderResponse> {
        override fun createFromParcel(parcel: Parcel): OrderResponse {
            return OrderResponse(parcel)
        }

        override fun newArray(size: Int): Array<OrderResponse?> {
            return arrayOfNulls(size)
        }
    }
}

2- The RideResponse class

public class RideResponse implements Parcelable {

    private String id;

    private User user;

    private OrderLocation location;

    private RideInfo rideInfo;

    private String orderType;

    private String repeatedDays ;

    private boolean repeated;

    public boolean isRepeated() {
        return repeated;
    }

    public void setRepeated(boolean repeated) {
        this.repeated = repeated;
    }

    public String getRepeatedDays() {
        return repeatedDays;
    }

    public void setRepeatedDays(String repeatedDays) {
        this.repeatedDays = repeatedDays;
    }




    public RideResponse() {
    }


    protected RideResponse(Parcel in) {
        id = in.readString();
        user = in.readParcelable(User.class.getClassLoader());
        location = in.readParcelable(OrderLocation.class.getClassLoader());
        rideInfo = in.readParcelable(RideInfo.class.getClassLoader());
        orderType = in.readString();
        repeatedDays = in.readString();
        repeated = in.readByte() != 0;

    }

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

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

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public OrderLocation getLocation() {
        return location;
    }

    public void setLocation(OrderLocation location) {
        this.location = location;
    }

    public RideInfo getRideInfo() {
        return rideInfo;
    }

    public void setRideInfo(RideInfo rideInfo) {
        this.rideInfo = rideInfo;
    }

    public String getOrderType() {
        return orderType;
    }

    public void setOrderType(String orderType) {
        this.orderType = orderType;
    }

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {

        dest.writeString(id);
        dest.writeParcelable(user, flags);
        dest.writeParcelable(location, flags);
        dest.writeParcelable(rideInfo, flags);
        dest.writeString(orderType);
        dest.writeString(repeatedDays);
        dest.writeByte((byte) (repeated ? 1 : 0));

    }

}

3- BigRideResponse is the same as RideResponse but with extra fields

4- Code passing the parcelable

Intent intent = new Intent(getContext(), RatingActivity.class);
        intent.putExtra(ApplicationConstants.ExtrasTag.ORDER_RESPONSE, mOrderResponse);
        getViewCallback().openRatingScreen(intent, REQUEST_CODE_RATE);

5 - Code retrieving the parcelable

mOrderResponse = intent.getExtras().getParcelable(ApplicationConstants.ExtrasTag.ORDER_RESPONSE);

And after some time-wasting, I tried to convert the Kotlin Data Class(OrderResponse) to a regular Java POJO and implemented Parcelable and boom it worked fine !!

So I'm guessing that using Parcelable data classes with Java Bundles doesn't seem to work so I wanted to know why exactly? Isn't kotlin Classes mapped to Java Classes so they are the same?

Answer 1

You need to send object as Parcelable to send the Data class objects via Intent like:

Here i am using Kotlin to create intent object

val intent = Intent(context, RatingActivity::class.java)
intent.putParcelableArrayListExtra(ApplicationConstants.ExtrasTag.ORDER_RESPONSE, mOrderResponse)

And now need to get the result as Parcelable like this.

Make sure create object of Data Class like this and get the Intent value in the object

//object create of ArrayList
    private var mOrderResponseViaIntent= ArrayList<OrderResponse>()


    mOrderResponseViaIntent= intent.getParcelableArrayListExtra<OrderResponse>(ApplicationConstants.ExtrasTag.ORDER_RESPONSE)
