Class IAPClientPaymentManager

java.lang.Object
  com.nokia.mid.payment.IAPClientPaymentManager

public final class IAPClientPaymentManager
extends java.lang.Object

This is the main class for initiating and managing the purchase process for the purchaseable items in an application. Its methods are asynchronous with responses received from the underlying implementation callbacks All API methods except getProductData() will initiate the user authentication by Single-Sign On (SSO).The IAPClientPaymentManager class handles a single API function call at a time. If a second request is made while response is pending from a previous function call, a failure value is returned indicating that this request shall not be processed and no callback can be expected for this request.

Provides information about purchasable items for the publisher application for building a catalog list. The productDataReceived() callback returns a ProductData structure for each of the productIDs. The callback is sent only if the return value is SUCCESS. Upon success the method schedules a callback which is dispatched to the application at some suitable time instance in future.

Parameters:

productId - The productId of the purchaseable items. Publishers register sub-products(IAP) with Nokia store to receive product IDs

Returns:

The return is an integer value. The value is one of the following:

SUCCESS: The method call succeeded. IAP API sends the productDataReceived() callback to the publisher application. .

FAIL: The method call failed. IAP API does not send the productDataReceived() callback to the publisher application.

getProductData

public int getProductData(java.lang.String[] productIdList)

Provides information about purchasable items for the publisher application for building a catalog list. The productDataListReceived() callback returns ProductData structure for a list of requested productIDs. The callback is sent only if the return value is SUCCESS. Upon success the method schedules a callback which is dispatched to the application at some suitable time instance in future.

Parameters:

productIdList - The productIds of a list of purchaseable items. Publishers register sub-products(IAP) with Nokia store to receive product IDs

Returns:

The return is an integer value. The value is one of the following:

SUCCESS: The method call succeeded. IAP API sends the productDataListReceived() callback to the publisher application. .

FAIL: The method call failed. IAP API does not send the productDataListReceived() callback to the publisher application.

purchaseProduct

public int purchaseProduct(java.lang.String productId,
                           int forceRestorationFlag)

Initiates the purchase flow. If forceRestorationFlag is set and the item to be purchased is restorable, the purchase flow is automatically transformed to a restoration flow. Only Nokia DRM encrypted items can be restored using IAPClient API.

The function call results in the purchaseCompleted() callback during execution if the return value is positive: This provides the purchase result, when the Nokia Store back end has completed the purchase and the purchase data is available for the client application. Upon success the method schedules a callback which is dispatched to the application at some suitable time instance in future.

Parameters:

productId - The ID of the product to be purchased. Publishers register sub-products(IAP) with Nokia store to receive product IDs

forceRestorationFlag - the flag for selecting forcedRestoration when available Possible values are one of the constants defined in this class, NO_FORCED_RESTORATION or FORCED_AUTOMATIC_RESTORATION

Returns:

The return is an integer value. The value is one of the following:

SUCCESS: The method call succeeded. IAP API sends the purchaseCompleted() callback to the publisher application.

FAIL: The method call failed. IAP API does not send the purchaseCompleted() callback to the publisher application.

restoreProduct

public int restoreProduct(java.lang.String productId,
                          int authenticationMode)

Initiates the restoration flow. Only Nokia DRM encrypted items can be restored using IAPClient API. The function call results in the restorationCompleted() callback during the execution if the return value is positive This provides the result of the restoration, when it is completed by the Nokia Store back end and the restoration data is available for the client application. Upon success the method schedules a callback which is dispatched to the application at some suitable time instance in future.

Parameters:

Returns:

The return is an integer value. The value is one of the following:

SUCCESS: The method call succeeded. IAP API sends the restorationCompleted() callback to the publisher application.

FAIL: The method call failed. IAP API does not send the restorationCompleted() callback to the publisher application.

getRestorableProducts

public int getRestorableProducts(int authenticationMode)

Provides a list of Nokia Store items related to the given application ID that are restorable via IAPClient API. The restorableProductsReceived() callback function returns the list of restorable products. The callback function is called only if the return value is positive. Upon success the method schedules a callback which is dispatched to the application at some suitable time instance in future.

Parameters:

authenticationMode - Defines whether restorable products are fetched silently without asking the user authentication or not

Returns:

The return is an integer value. The value is one of the following:

SUCCESS: The method call succeeded. IAP API sends the restorableProductsReceived() callback to the publisher application. .

FAIL: The method call failed. IAP API does not send the restorableProductsReceived() callback to the publisher application.

getUserAndDeviceId

public int getUserAndDeviceId(int authenticationMode)

Provides all necessary information about the current user and the device for the publisher service to restore non-Nokia DRM encrypted data to the device. The userAndDeviceDataReceived() callback returns the data in hashed form. The callback is sent only if the return value is positive. Upon success the method schedules a callback which is dispatched to the application at some suitable time instance in future.

Parameters:

authenticationMode - Defines whether the user and the device data are fetched silently without asking user authentication or not Possible values are one of the constants defined in this class, DEFAULT_AUTHENTICATION or ONLY_IN_SILENT_AUTHENTICATION

Returns:

The return is an integer value. The value is one of the following:

SUCCESS: The method call succeeded. IAP API sends the userAndDeviceDataReceived() callback to the publisher application. .

FAIL: The method call failed. IAP API does not send the userAndDeviceDataReceived() callback to the publisher application.

getDRMResourceAsStream

public java.io.InputStream getDRMResourceAsStream(java.lang.String name)

This provides the client application access to DRM encrypted resource files inside JAR. eg. Possible location Jar-root/res/drm/data/level_1 /level_2 This is used after receiving the PurchaseTicket from a successful purchase flow or restoration flow. Finds a drm resource with a given name inside the application's JAR file. This method returns null if no resource with this name is found in the application's JAR file.

The resource names can be represented in two different formats: absolute or relative.

Absolute format:

/packagePathName/resourceName

Relative format:

resourceName

In the absolute format, the programmer provides a fully qualified name that includes both the full path and the name of the resource inside the JAR file. In the path names, the character "/" is used as the separator.

In the relative format, the programmer provides only the name of the actual resource. Relative names are converted to absolute names by the system by prepending the resource name with the fully qualified package name of class upon which the geDRMResourceAsStream method was called.

Parameters:

name - name of the desired resource

Returns:

a java.io.InputStream object.
