After a ling time, Android developers will now be able to efficiently monetize their Android applications with the new in-app billing system that has made its way into the Android Market today. As the model has been extremely successful on iOS, developers were keen to try it on Android. Starting today, developers can sell stuff from within the App, and charge users for it.
In-App billing can be helpful for users too as most developers tend to make the App free, and then sell stuff from within the App to effectively monetize. This system also lets users unlock new and hidden features by paying for them. Google announced that In-App billing was about to be a part of the Android Market, but this could be huge for developers who can now implement it in their own Apps and sell something.
