AIDL

Para notificar al comercio sobre los cambios nuevos, usa el servicio PaymentDetailsUpdateService declarado en AndroidManifest.xml de Chrome. Para usar este servicio, crea dos archivos AIDL con el siguiente contenido:

app/src/main/aidl/org/chromium/components/payments/IPaymentDetailsUpdateService

package org.chromium.components.payments;
import android.os.Bundle;

interface IPaymentDetailsUpdateServiceCallback {
    oneway void updateWith(in Bundle updatedPaymentDetails);

    oneway void paymentDetailsNotUpdated();
}

app/src/main/aidl/org/chromium/components/payments/IPaymentDetailsUpdateServiceCallback

package org.chromium.components.payments;
import android.os.Bundle;
import org.chromium.components.payments.IPaymentDetailsUpdateServiceCallback;

interface IPaymentDetailsUpdateService {
    oneway void changePaymentMethod(in Bundle paymentHandlerMethodData,
            IPaymentDetailsUpdateServiceCallback callback);

    oneway void changeShippingOption(in String shippingOptionId,
            IPaymentDetailsUpdateServiceCallback callback);

    oneway void changeShippingAddress(in Bundle shippingAddress,
            IPaymentDetailsUpdateServiceCallback callback);
}
