Google Pay API Release Notes for Android

Added support for Dynamic Price Updates via callbacks in the Google Pay API for Android. This feature allows merchants to update the payment sheet dynamically based on user actions (e.g., changing shipping address or shipping option). This requires version 20.0.0 or higher of the com.google.android.gms:play-services-wallet library. New objects introduced include PaymentDataCallbacks, PaymentDataRequestUpdate, IntermediatePaymentData, and PaymentAuthorizationResult.

Expanded the Gateway test cards to support billing addresses from 27 markets (previously US only). This allows merchants to test end-to-end payment flows with country-specific billing address in the TEST environment. The added markets include United Kingdom, France, Germany, Spain, Japan, Hong Kong, Brazil, and 20 other countries.

Added the FULL-ISO3166 option to the format property of the BillingAddressParameters object and introduced a new format property to the ShippingAddressParameters object. Updated the returned properties of the IntermediateAddress and Address objects to include a new format property, iso3166AdministrativeArea. This change should be non-breaking for existing implementations. Check the reference pages for more information.
