question

We are using our own app to trigger payments on Station Duo/Pro devkit's Merchant facing, swipe, tap or insert operations are being displayed on the customer facing and working correctly. But in case of manual transaction only card entry fields are not displayed either on customer facing or the merchant facing. My Code for charging above payments is below and screen responses are attached in the images below.

if (payment_method.equals("credit_card")) {
    builder.cardOptions(PaymentRequestIntentBuilder.CardOptions.Instance(
            CardEntryMethod.CardReaders(),                                              
            null,                                                                       
            true));                                                                     
} else if (payment_method.equals("manual_card")) {
    builder.cardOptions(PaymentRequestIntentBuilder.CardOptions.Instance(
            CardEntryMethod.Manual(),                                                  
            false, // also tried with true & null but same                                                                    
            true));
}
