Why is java.lang.Integer ignored in auto Parcelable implementation by Android Studio?

Question

This is the automatic Parcelable implementation generated by Android Studio. It somehow, always ignores resultCode which is of type Integer

public class TestParceable implements Parcelable {

        private String message;
        private Integer resultCode; //an Integer   

    protected TestParceable(Parcel in) {
        message = in.readString();
    }

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

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

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

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

On the other hand, if I change the type of resultCode to int, the automatic Parcelable implementation considers it.

public class TestParceable implements Parcelable {

        private String message;
        private int resultCode; //an int

protected TestParceable(Parcel in) {
    message = in.readString();
    resultCode = in.readInt();
}

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

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

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

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

Am I missing something here or is this and Android Studio bug?

Answer 1

It's a bug (https://code.google.com/p/android/issues/detail?id=233034) which is fixed for Studio 2.4.
