No, it does not. The section on getters and setters is entitled "Avoid Internal Getters/Setters" (emphasis added). It refers to using getters and setters, as opposed to field access, inside a class. It does not suggest that getters and setters should be avoided in general.

How create Parcelable implemented model class?

You create all Parcelable classes the same way:

• add implements Parcelable to the class definition
• implement writeToParcel()
• implement describeContents()
• add the CREATOR static field

None of that has anything to do with getters or setters. The MyParcelable sample class shown in the JavaDocs for Parcelable does not use a getter or a setter for the mData field.

Similarly, using parcelabler.com, here is Parcelable implementation of a Chair:

public class Chair implements Parcelable {
  private String material;
  private int numLegs;

    protected Chair(Parcel in) {
        material = in.readString();
        numLegs = in.readInt();
    }

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(material);
        dest.writeInt(numLegs);
    }

    @SuppressWarnings("unused")
    public static final Parcelable.Creator<Chair> CREATOR = new Parcelable.Creator<Chair>() {
        @Override
        public Chair createFromParcel(Parcel in) {
            return new Chair(in);
        }

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

It also does not use getters or setters.
