What's the this fragment's name?

Hi, I build an app and I need to use the fragment attached in the image but I don’t know what’s it name and which line I should modify?

try {
** Intent collectPaymentIntent = new Intent(Intents.ACTION_COLLECT_PAYMENT);**
** collectPaymentIntent.putExtra(Intents.INTENT_EXTRAS_PAYMENT, payment);**
** startActivityForResult(collectPaymentIntent, COLLECT_PAYMENT_REQUEST);**
}

What’s the meaning this value “13132” in the next line:

private static final int COLLECT_PAYMENT_REQUEST = 13132; ?

Would you please clarify which source code you are referring to ? May be post a link so it’s easy for us to answer your questions.
