Parcelable and boxed classes

Question

I've got the following class:

public class E implements Parcelable {
  @SerializedName("a")
  private String a= null;
  @SerializedName("b")
  private BigDecimal b= null;
  @SerializedName("c")
  private String c= null;
  @SerializedName("d")
  private String d= null;    

  protected E(Parcel in) {
   number = in.readString();
   expirationYear = in.readString();
   expirationMonth = in.readString();
  }

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

  @Override
  public E[] newArray(int size) {
      return new E[size];
  }};
}
  @Override
  public int describeContents() {
     return 0;
  }

   @Override
    public void writeToParcel(Parcel dest, int flags) {
     dest.writeString(number);
     dest.writeString(expirationYear);
     dest.writeString(expirationMonth);
    }
}

How to parcel the data member b? Or better yet, how to parcel boxed types?

As you can see, the writeToParcel method misses the data member b as well as the protected c'tor.

How to use Parcelable on non-primitive types?

A good way to solve this problem (in my opinion) is to create your class extending BigDecimal and implements Parcelable interface on it.
