バイト配列を含む Parcelable クラスを作成しようとしています。私はあらゆる種類のことを試してきましたが、パーセルブルを自分の意図に合わせたい場合はまだ失敗しているようです.

public class Car implements Parcelable{

private String numberPlate;
private String objectId;
private byte[] photo;
private String type;
private ParseGeoPoint location;
private ParseUser owner;
private String brand;
private double pricePerHour;
private double pricePerKm;
public static final String TYPES[] = {"Cabrio", "Van", "SUV", "Station", "Sedan", "City", "Different"};


public Car(String numberPlate, byte[] bs, String type, ParseGeoPoint location, String brand) {

    this.numberPlate = numberPlate;
    this.photo = bs;
    this.type = type;
    this.brand = brand;
    this.setLocation(location);
    this.owner = ParseUser.getCurrentUser();
}

public Car(Parcel in){
    readFromParcel(in);
}

 public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public Car createFromParcel(Parcel in) {
            return new Car(in);
        }

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



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

public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(type);
    dest.writeString(numberPlate);
    dest.writeString(brand);
    dest.writeDouble(pricePerHour);
    dest.writeDouble(pricePerKm);
    dest.writeString(objectId);
    dest.writeByteArray(photo);


}

public void readFromParcel(Parcel in){
    this.type = in.readString();
    this.numberPlate = in.readString();
    this.brand = in.readString();
    this.pricePerHour = in.readDouble();
    this.pricePerKm = in.readDouble();
    this.objectId = in.readString();
    byte[] ba = in.createByteArray();
    in.unmarshall(ba, 0, ba.length);
    this.photo = ba;

}

バイト配列を含めなくても問題なく動作します..

Why you use createByteArray ?? I revised your code in a way it should work... 

public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(type);
    dest.writeString(numberPlate);
    dest.writeString(brand);
    dest.writeDouble(pricePerHour);
    dest.writeDouble(pricePerKm);
    dest.writeString(objectId);
    dest.writeInt(photo.length());
    dest.writeByteArray(photo);
}



public void readFromParcel(Parcel in){
    this.type = in.readString();
    this.numberPlate = in.readString();
    this.brand = in.readString();
    this.pricePerHour = in.readDouble();
    this.pricePerKm = in.readDouble();
    this.objectId = in.readString();
    this.photo = new byte[in.readInt()];
    in.readByteArray(this.photo);
}
