Answer 1

You need to start the second activity with startActivityForResult:

http://developer.android.com/reference/android/app/Activity.html#startActivityForResult%28android.content.Intent,%20int%29

In onActivityResult, you should also check the resultCode is RESULT_OK, rather than the requestCode.

Answer 2

I believe you should be using startActivityForResult() instead of startActivity().

Answer 3

first activity

Intent in = new Intent(getApplicationContext(),ShippingActivity.class);
            startActivityForResult(in, 0);


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == 0){
            if(resultCode ==1){
tvDeliverTo.setText(data.getStringExtra("DeliveryAdressKEY"));              
            }
        }
    }

and second activity

Intent in = new Intent();
in.putExtra("DeliveryAdressKEY", tvAdress.getText().toString());
setResult(1, in);
finish();

and now is working
