Google Play Services




In 2012, Google began decoupling certain aspects of its Android operating system (particularly its core applications) so they could be updated through the Google Play store independently of the OS. One of those components, Google Play Services, is a closed-source system-level process providing APIs for Google services, installed automatically on nearly all devices running Android 2.2 "Froyo" and higher. With these changes, Google can add new system functionality through Play Services and update apps without having to distribute an upgrade to the operating system itself. As a result, Android 4.2 and 4.3 "Jelly Bean" contained relatively fewer user-facing changes, focusing more on minor changes and platform improvements.

Google states in its Developer Policy Center that "Google Play supports a variety of monetization strategies to benefit developers and users, including paid distribution, in-app products, subscriptions, and ad-based models", and requires developers to comply with the policies in order to "ensure the best user experience". It requires that developers charging for apps and downloads through Google Play must use Google Play's payment system. In-app purchases unlocking additional app functionality must also use the Google Play payment system, except in cases where the purchase "is solely for physical products" or "is for digital content that may be consumed outside of the app itself (e.g. songs that can be played on other music players)." Support for paid applications was introduced on February 13, 2009 for developers in the United States and the United Kingdom, with support expanded to an additional 29 countries on September 30, 2010. The in-app...
