Summary

Pulled internally from #12247 by @igorescodro

Adding createTwint() function inside PaymentMethodCreateParams, allowing the payment provider to be confirmed by the Android app using PaymentLauncher.confirm(). Test and example classes were created to cover this new implementation.

Motivation

In the current Android SDK, it's not possible to use ConfirmPaymentIntentParams with TWINT, like with other payment methods such as PayPal, CashApp, NolPay, etc. We discussed with the Stripe Support and they informed us that there is no support yet. The goal of this PR is to speed up the inclusion of this new functionality.

Trying to create it with the existing APIs, will result in a StripeError.

fun confirmTwintPayment() {
  val paymentLauncher = PaymentLauncher.create(
    fragment = this,
    publishableKey = publishableKey // Switzerland Stripe Key,
    callback = { /* handle payment result */ }
  )

  val paymentIntentParams = ConfirmPaymentIntentParams.create(
    clientSecret = clientSecret, // Provided by the backend
    paymentMethodType = PaymentMethod.Type.Twint,
  )

  // callback returns `PaymentResult.Failed`
  paymentLauncher.confirm(paymentIntentParams)
}
StripeError(
    type = "invalid_request_error", 
    message = "You cannot confirm this PaymentIntent because it's missing a payment method. You can either update the PaymentIntent with a payment method and then confirm it again, or confirm it again directly with a payment method or ConfirmationToken.", 
    code = "payment_intent_unexpected_state", 
    param = null, 
    declineCode = null, 
    charge = null, 
    docUrl = "https://stripe.com/docs/error-codes/payment-intent-unexpected-state", 
    extraFields = null
)

This new API, allows to use TWINT:

fun confirmTwintPayment() {
  val paymentLauncher = PaymentLauncher.create(
    fragment = this,
    publishableKey = publishableKey // Switzerland Stripe Key,
    callback = { /* handle payment result */ }
  )

  val twintParams = PaymentMethodCreateParams.createTwint()

  val paymentIntentParams = ConfirmPaymentIntentParams.createWithPaymentMethodCreateParams(
      paymentMethodCreateParams = twintParams,
      clientSecret = clientSecret, // Provided by the backend
  )

  // confirmation UX open and callback returns `PaymentResult.Success` when approved
  paymentLauncher.confirm(paymentIntentParams)
}
