java.io.NotSerializableException while passing interface through intent.putExtra

Here's my interface that I extended from Serializable:

public interface InstaListener extends Serializable {
    void onSuccess(String response);
    void onFailure(int code, String reason);
}

Here's how I am passing this Listener between two activities:

InstaListener iListener = new InstaListener() {
            @Override
            public void onSuccess(String response) {

            }

            @Override
            public void onFailure(int code, String reason) {

            }
        };

Intent intent = new Intent(activity, Insta.class);
            intent.putExtra("email", email);
            intent.putExtra("phone", phone);
            intent.putExtra("purpose", purpose);
            intent.putExtra("amount", amountstr);
            intent.putExtra("name", name);
            intent.putExtra("env", env);
            intent.putExtra("listener", iListener);
            activity.startActivity(intent);

Here's how I am receiving the listener in Insta class. 

instaListener = (InstaListener) getIntent().getSerializableExtra("listener");

I have searched many posts but nothing explains why I get the error: java.io.NotSerializableException

Any help?

Your method-local implementation of InstaListener is an inner class of instamojo.library.InstamojoPay, which isn't Serializable. You probably don't want it to be Serializable, so the solution is to write your InstaListener implementation as a static nested class, instead of a method-local inner class.

You have an inner class of instamojo.library.InstamojoPay, it's not serializable.

To avoid this exception, add java.io.Serializable to your inner class or add transient keyword to your inner class object declaration
