Same object access in different activity?

Question

I have a Java class say J.java

//j.java
class J
{


}

and I have 2 activity say A1,A2. In A1 I created a object of class J.

A1
{
  J obj = new J();
}

Question- I want to access the same object(obj) in A2.

A2
{
   obj // how can I access this object here? this is created in A1.
}

Couple of options. 1. Make the class J as a static class or you can use singleton pattern. 2. Wrap it in an intent or bundle and then send it to other activity. — Sunil Mishra, Aug 13 '13 at 05:54

Implement Parcelable for that object. And send that object from A1 to A2 into intent extra.

one way to have a single instance of J across the activities is to have a singleton for the J object.

one way of doing this is having an instance in the application level (have a J instance in a class that extends Application.

the other way is doing this:

class J {
    private static J instance = null;

    private J() {
    }

    public static J get() {
        return instance;
    }
}

You can create an Base or Parent activity. Initialize your object in base activity and extend your all classes from base or application activity.
