Я хочу знать точно,

whether should I used parcelable or serialization technique for sending data from one activity to other? is it compulsory to use one of them for sending data from one to other? when should I use them? and the exact difference between them and performance of both of them in java aspects.

Заранее спасибо.

 public class GetSetClass implements Serializable {
    private int dt = 10;

    /** pass any object, drwabale */
    public int getDt() {
        return dt;
    }

    public void setDt(int dt) {
        this.dt = dt;
    }
}
