The Android Market has had in-app billing enabled, allowing developers of Android apps to offer upgrades, virtual goods, extra levels in games and other services from within their titles. Using the same checkout system as the Market itself, Google will take the usual 30-percent cut from developers’ proceeds and do all the hard work when it comes to processing. The system will also allow for try-and-buy apps, offering a test period of use and then the ability to unlock the full title rather than having to re-download the app.
Google has worked with the developers behind Tap Tap Revenge, Comics, Gun Bros, Deer Hunter Challenge HD, WSOP3 and Dungeon Defenders: FW Deluxe to demonstrate the in-app billing system, and the updated versions are now available in the Android Market. There are more details for developers here.
