how to use Parcelable for custom type objects/variable in a class (Android)

Question

I have make a class which has a custom class object/variable and i want to make this class parcelable for passing it in to the intend so that i receive the reponse in next activity

MORE DETAILED

I Have class first ie

public class Data implements Parcelable{


    @SerializedName("barlist")
    Bar bar_list[];



    public Bar[] getBarLst() {
        return bar_list;
    }

    public void setBarLst(Bar lst[]) {
        this.bar_list = lst;
    }



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

    @Override
    public void writeToParcel(Parcel parcel, int flags) {
        parcel.writeParcelableArray(bar_list, Parcelable.PARCELABLE_WRITE_RETURN_VALUE);

    }
    public static final Parcelable.Creator<Data> CREATOR = new Creator<Data>() { 
           public Data createFromParcel(Parcel source) { 
               Data data = new Data(); 
               data.bar_list = (Bar[]) source.readParcelableArray(this.getClass().getClassLoader());

               return data; 
           }

        @Override
        public Data[] newArray(int size) {
            // TODO Auto-generated method stub
            return new Data[size];
        } 
     };

}

In the above class i have a custom type object/variable ie of type Bar

and my next class is ::

public class Bar implements Parcelable{

    @SerializedName("name")
    String Name;

    @SerializedName("sex")
    String sex;

    @SerializedName("type")
    String type;

    @SerializedName("userid")
    String userId;

    @SerializedName("contactno")
    String ContactNo;

    @SerializedName("zipcode")
    String zipCode;

    @SerializedName("address")
    String Address;

    @SerializedName("email")
    String Email;



    public String getName() {
        return Name;
    }
    public void setName(String name) {
        Name = name;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
    public String getUserId() {
        return userId;
    }
    public void setUserId(String userId) {
        this.userId = userId;
    }
    public String getContactNo() {
        return ContactNo;
    }
    public void setContactNo(String contactNo) {
        ContactNo = contactNo;
    }
    public String getZipCode() {
        return zipCode;
    }
    public void setZipCode(String zipCode) {
        this.zipCode = zipCode;
    }
    public String getAddress() {
        return Address;
    }
    public void setAddress(String address) {
        Address = address;
    }
    public String getEmail() {
        return Email;
    }
    public void setEmail(String email) {
        Email = email;
    }
    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    @Override
    public void writeToParcel(Parcel parcel, int flags) {
        parcel.writeString(Name);
        parcel.writeString(sex);
        parcel.writeString(type);
        parcel.writeString(userId);
        parcel.writeString(ContactNo);
        parcel.writeString(zipCode);
        parcel.writeString(Address);
        parcel.writeString(Email);
    }

    public static final Parcelable.Creator<Bar> CREATOR = new Creator<Bar>() { 
           public Bar createFromParcel(Parcel source) { 
               Bar barlst = new Bar(); 
               barlst.Name = source.readString(); 
               barlst.sex = source.readString(); 
               barlst.ContactNo = source.readString(); 
               barlst.type = source.readString(); 
               barlst.userId = source.readString(); 
               barlst.zipCode = source.readString(); 
               barlst.Address = source.readString(); 
               barlst.Email = source.readString(); 
               return barlst; 
           }

        @Override
        public Bar[] newArray(int size) {
            // TODO Auto-generated method stub
            return new Bar[size];
        } 
     };
}

I want to make a data class (first class) object be parcelable so in my first activity i did some this like this

EmptyRequest empt = new EmptyRequest();
Data responsestr = userManager.getMainMenuItems(empt,"url","Post","getBarList");

Intent myintent = new Intent(MainMenuPageActivity.this, BarListPageActivity.class);
Bundle mbundle = new Bundle();
mbundle.putParcelable("BARLIST", responsestr);
myintent.putExtras(mbundle);
startActivity(myintent);

till here my code worked fine and i kept the responsestr of type data into the parcelable

and in my next acitivity i tried to fetch data object like this

Data responseStr = (Response)getIntent().getParcelableExtra("BARLIST");

to fetch the object of type data but this didnt work and give exception the second activity class not found but my debugger reaches in the second activity.

Thanks in advance....
