question

When I make a transaction from sale app from using custom merchant tender and sending result for success payment the tip amount is not coming while it is coming from register app on clover mini. The sample code is given below.

Intent data2 = new Intent();
data2.putExtra(Intents.EXTRA_AMOUNT, Math.round(order_amount * 100));
data2.putExtra(Intents.EXTRA_TIP_AMOUNT, Math.round(tip_amount * 100));
setResult(RESULT_OK, data2);
finish();
