Question

How can I write singleton to work through several processes? Is it possible?
For example I have code that works with Remote Service in Android. How can I write singleton for this purpose?

UPDATE:

public enum Singleton {
    INSTANCE;

    int a = 0;

    public int getA() {
        return a;
    }

    public void setA(int a) {
        this.a = a;
    }   
}



    void doFromFirstProcess(){
        Singleton.INSTANCE.setA(1);
    }

    void doFromSecondProcess(){
        Singleton.INSTANCE.getA(); //0
    }

Why does it not work? What is wrong with my code?

Answer 1

No, seperate processes do not share any memory.
