http://play.google.com/about/developer-content-policy.html http://play.google.com/about/developer-content-policy.html * Paid and Free Applications - App purchases: Developers charging for applications and downloads from Google Play must do so by using Google Play's payment system. - In-app purchases: Developers offering additional content, services or functionality within an application downloaded from Google Play must use Google Play's payment system as the method of payment, except: . where payment is primarily for physical goods or services (e.g. buying movie tickets; e.g. buying a publication where the price also includes a hard copy subscription); or . where payment is for digital content or goods that may be consumed outside of the application itself (e.g. buying songs that can be played on other music players) Does that mean I cannot use any 3rd party payment system?
