com.google.android.gms.wallet.Payments

Class Overview

Entry point for interacting with Wallet buyflow APIs.

To allow the user to select and change the account associated with the transaction and Google transaction ID, use null or simply do not set it using setAccountName(String). No special action is required when a user changes the selected account through the UI in this case, and the Google transaction ID associated with the transaction can continue to be used.

To specify the account and prevent the user from selecting another account, set the account using setAccountName(String). To change the account, construct a new GoogleApiClient with the new account and do not reuse the Google transaction ID associated with the old account - this is a new transaction.

We recommend that you apply for API access at http://getinstantbuy.withgoogle.com/ before starting development. During development, use the sandbox environment by specifying ENVIRONMENT_SANDBOX using setEnvironment(int). For production access, you must specify ENVIRONMENT_PRODUCTION.

Public Methods

public abstract void changeMaskedWallet (GoogleApiClient googleApiClient, String googleTransactionId, String merchantTransactionId, int requestCode)

This method brings up a Google Wallet selector screen to allow your customer to select a new payment instrument or shipping address from their Google Wallet.

Parameters
googleApiClient An instance of GoogleApiClient configured to use the Wallet API
googleTransactionId Required field. Must be identical to the value returned in an earlier MaskedWallet in the same transaction.
merchantTransactionId Optional merchant identifier for the transaction. The value will be echoed back in MaskedWallet, but is not otherwise used by the Wallet API. To omit, pass null
requestCode will be passed back in onActivityResult where you can retrieve the result via EXTRA_MASKED_WALLET.

public abstract void checkForPreAuthorization (GoogleApiClient googleApiClient, int requestCode)

This API checks to see if a user has previously authorized the application to access their Wallet account.

Parameters
googleApiClient An instance of GoogleApiClient configured to use the Wallet API
requestCode will be passed back in onActivityResult where you can retrieve the result via EXTRA_IS_USER_PREAUTHORIZED.

public abstract void isNewUser (GoogleApiClient googleApiClient, int requestCode)

Checks if this is a new user, i.e. if they have used Instant Buy to make a purchase for your app before or not. If the user has multiple accounts on the device, each will be checked. If any of the accounts has been used to make an Instant Buy purchase with your app, then false will be returned. True is only returned if none of the accounts on the device have used Instant Buy to make a purchase with your app.

Parameters
googleApiClient An instance of GoogleApiClient configured to use the Wallet API
requestCode will be passed back in onActivityResult where you can retrieve the result via EXTRA_IS_NEW_USER.

public abstract void loadFullWallet (GoogleApiClient googleApiClient, FullWalletRequest request, int requestCode)

Requests a FullWallet, which contains the payment credentials. You can retrieve the FullWallet in onActivityResult using the requestCode that you provide to this method. If there is a problem with the transaction then the Google Wallet selector will be shown and a MaskedWallet will be returned to reflect new selections by the user.

This function should only be called when the customer confirms the purchase.

Important: Because the credentials are in plain text it is important to transfer the payment credentials following PCI standards.

Parameters
googleApiClient An instance of GoogleApiClient configured to use the Wallet API
requestCode will be passed back in onActivityResult where you can retrieve the result via EXTRA_FULL_WALLET or EXTRA_MASKED_WALLET if the user had to make new selections.

public abstract void loadMaskedWallet (GoogleApiClient googleApiClient, MaskedWalletRequest request, int requestCode)

If an application has authorization, loadMaskedWallet() allows you to skip the Google Wallet selector and directly request the masked payment credentials. This provides a more seamless purchase experience for your customers. When you call this method, the Google Wallet selector will be shown only if necessary. Either way, you can retrieve the MaskedWallet in onActivityResult using the specified requestCode.

Parameters
googleApiClient An instance of GoogleApiClient configured to use the Wallet API
requestCode will be passed back in onActivityResult where you can retrieve the result via EXTRA_MASKED_WALLET.

public abstract void notifyTransactionStatus (GoogleApiClient googleApiClient, NotifyTransactionStatusRequest request)

Sends a notification to Google on whether the transaction succeeded or failed. This should always be called after payment processing as well as any failed validation checks.

Parameters
googleApiClient An instance of GoogleApiClient configured to use the Wallet API
