A post on Android Developers yesterday revealed that the in-app billing which Google has been working on releasing into the Android Market is finally ready for developers to begin testing it. In addition, it was also announced that the service will be launched next week, just before the end of the quarter.
Back when Google announced the web client of the Android Market in January, they made it known that they were working on adding in-app billing to the Android Market this quarter, and with about a week left in the quarter, it appears as though Google will indeed make their deadline.
To get ready for the launch next week, Google have enabled developers to begin upload and end-to-end testing of apps which make use of in-app billing. Interested developers should upload their apps to the Developer Console, create a corresponding catalog of in-app products for those apps, and set prices for said products.
During the testing phase, the in-app billing service will interact with the apps just as it will when the service goes live in the coming week. Apps will not be able to be published to users until the service is launched next week.
