This library wraps the GooglePlayBilling base library. It returns the results in structures as they are built in the Google accounting system.
The library does not display any messages; it only returns results: BillingResult, ProductResult, or PurchasedResult. It also generates the events described below.
When a ProductResult is returned, first read the ResponseCode value. If equal to CODE_OK, load the data from the list; otherwise, handle an error.
The principle of using the library is in the example application.
