For passing stuff from Activity-A to Activity-B, use a bundle and pass it in
the intent while starting the target activity.
Intent intent = new Intent(ActivityA.class, ActivityB.class);
intent.putExtra("name", "myName");
intent.putExtra("age", 24);
startActivity(intent);
>From the target activity, retrieve the bundle and access the passed data.
Bundle extras = intent.getExtras();
//get your stuff from the bundle.
