Question

I'm getting this dialog

   implementation 'com.paypal.sdk:paypal-android-sdk:2.16.0'

   val intent = Intent(this, PayPalService::class.java)
    intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config)
    startService(intent)

   private var config =
    PayPalConfiguration()
        .environment(PayPalConfiguration.ENVIRONMENT_SANDBOX)
        .clientId(AppConstants.getPayPalClientID())

   val payment = PayPalPayment(
        BigDecimal(7),
        "USD",
        "abcd",
        PayPalPayment.PAYMENT_INTENT_ORDER
    )
    payment.invoiceNumber(getting this from my backend)


    val intent = Intent(this, PaymentActivity::class.java)

    // send the same configuration for restart resiliency

    // send the same configuration for restart resiliency
    intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config)

    intent.putExtra(PaymentActivity.EXTRA_PAYMENT, payment)

    startActivityForResult(intent, 0)

Answer 1

That SDK has been deprecated for years and is now sunset (end of life). It cannot be used.

If you need a native SDK for PayPal payments, use Braintree's. Here is some documentation: https://developer.paypal.com/docs/archive/checkout/how-to/braintree-integration/ , the rest of it is on Braintree's site. Do not create a gateway account. Use an access token from the bottom of developer.paypal.com applications for authentication to your PayPal account. You will need a webservice to get the client token.

For a non-native integration, use PayPal Checkout
