java - Make custom Parcelable containing byte array -


i'm trying make parcelable class contains byte array. have been trying sorts of things, still seems fail if want put parcelable intent.

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;  }

it works fine if don't include byte array..

why use createbytearray ?? revised code in way 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); }
