Google have just updated the Google Play policy regarding in-app billing services. From now on, developers will have to use Google Play’s in-app purchase and subscription services, instead of third-party ones. The reason for this act is to provide a more uniform billing experience among apps. This means you can’t pay via PayPal, Boku and other services, but via Google‘s own one. Developers have 30 days to update their apps to feature Google‘s services, if they don’t want their apps to be removed from the marketplace.
