Google Play Billing: The “Purchase Anywhere” Paradigm Shift
In the past few years, we have introduced new features into Google Play, that enable users to discover and purchase items and subscriptions in many new ways, from inside and outside the app.
Developers who have adopted these changes in their apps have seen improvements in user experience, and with it, substantial growth in revenue. However, integrating these features into an app or game requires a fundamental change in which you think about how purchases are made and consumed.
This session takes a deep dive into designing for Purchase Anywhere. We will talk about promotions, subscribe-and-install, cash purchases and pending transactions, and remote purchase approvals. All app and game developers using Google Play Billing are welcome to attend.

Purchases are done outside app
