Google has announced on its Android Developers blog that it is rolling out the new in-app billing version 3 for Android developers. The system that allows developers to sell content to their users through Android apps was improved in this update and makes it easier for developers to implement in-app purchases.

The in-app billing system that was first announced one and a half year ago, has been improved vastly and allows developers of both paid and free applications to earn extra money by selling virtual goods, virtual currency for games, try-and-buy services, and of course subscriptions for magazines and other kind of apps.

In version 3 of in-app billing, Google has introduced a number of new features that include improved design, which makes it easier for developers to write, debug, and maintain code. Google has also made it convenient for developers to integrate in-app billing in their apps by reducing the lines of code required for integration as tasks that needed several hundreds lines of code before can be implemented in as few as 50 now.

Google has also included a local caching feature that will bring faster API calls. The update also brings a more robust architecture, which will help in reducing the number of lost transactions. Another functionality that has been added in the version 3 of in-app billing is the ability to consume managed purchases and query for product information.

The updated in-app billing system is compatible with the latest Google Play app version and it’s now available to all Android developers who use this monetization option in their current apps. In-app billing also requires Android 2.2 or later on Android devices that run such apps. However, the subscription feature is not supported yet but Google has promised that it will be added soon.
