交易时UPI失败

Question

        String amount = mEditTextAmount.getText().toString();
    mEasyUpiPayment = new EasyUpiPayment.Builder()
            .with(this)
            .setPayeeVpa("akash123455190@okhdfcbank")
            .setPayeeName("AKASH R")
            .setTransactionId(mTransactionID)
            .setTransactionRefId(mTransactionID)
            .setDescription(mName + " : " + mPhoneNumber)
            .setAmount(String.valueOf(Float.parseFloat(amount)))
            .build();

    mEasyUpiPayment.setPaymentStatusListener(this);

@Override
public void onTransactionCompleted(TransactionDetails transactionDetails) {
    Log.d("rdsresdrs", transactionDetails.toString());
}


@Override
public void onTransactionSuccess() { 
}

@Override
public void onTransactionSubmitted() {
    Toast.makeText(this, "Pending", Toast.LENGTH_SHORT).show();
}

@Override
public void onTransactionFailed() {

    Toast.makeText(this, "Transaction Failed", Toast.LENGTH_SHORT).show();

}

@Override
public void onTransactionCancelled() {
    Toast.makeText(this, "Transaction Cancelled", Toast.LENGTH_SHORT).show();
}

@Override
public void onAppNotFound() {
    Toast.makeText(this, "App is not Installed on this Device", Toast.LENGTH_LONG).show();
}
