java - 如何使用 Android Studio 和 Java 在 UPI 支付网关中获取 resultCode 和 requestCode？

Question

我的问题是获得 UPI 支付网关的正确响应，例如“支付成功”或“错误”。我尝试了一点，但这会将 0 作为“resultCode”返回，将“1”作为“requestCode”返回。但我需要“resultCode”作为-1。使用此代码付款成功并且金额也被转移，但响应不准确。请帮我解决这个问题...

final int UPI_PAYMENT = 0;

payUsingUpi("TESTNAME", "testname@123","testing", "1");

public void payUsingUpi(  String name,String upiId, String note, String amount) {
        Log.e("main ", "name "+name +"--up--"+upiId+"--"+ note+"--"+amount);
        Uri uri = Uri.parse("upi://pay").buildUpon()
                .appendQueryParameter("pa", upiId)
                .appendQueryParameter("pn", name)
                .appendQueryParameter("tn", note)
                .appendQueryParameter("am", amount)
                .appendQueryParameter("cu", "INR")
                .build();
        Intent upiPayIntent = new Intent(Intent.ACTION_VIEW);
        upiPayIntent.setData(uri);
        Intent chooser = Intent.createChooser(upiPayIntent, "Pay with");
        if(null != chooser.resolveActivity(getPackageManager())) {
            startActivityForResult(chooser, UPI_PAYMENT);
        } else {
