Android Market Launches In-App Payments System

As  promised last week, today the Android Market launched an in-app billing system . Developers can now publish applications that support this system, and users of such applications will be able to make purchases in them.

The payment system within applications gives developers more opportunities to profit from their applications: try-and-buy model, virtual goods, updates and other payment models. If you are not familiar with this system, you can learn more about it in the help section of the Android Developers site.

Several applications using this service are already available, including Disney Mobile's Tap Tap Revenge ;Comics from ComiXology; Gun Bros , Deer Hunter Challenge HD  and  WSOP3 from Glu Mobile; and  Dungeon Defenders: FW Deluxe by Trendy Entertainment.

To try the new payment system in your applications, start with  detailed documentation and  a sample application that show how to implement the service in your application. Also, be sure to check out the  security guidelines to make sure your implementation is safe.
