This free service is a secure mechanism that helps Android programmers access all Android Market paid applications for app promotion agency. The only limitation of this application is that it can be installed only on compatible devices that provide a secure internal storage environment. During run time, with the inclusion of a set of libraries provided by Google, Android app can query the Android Market licensing server to determine the license status of the users. It returns information on whether the users are authorized to use the app based on stored sales records.

This real time licensing service provides more flexibility in choosing license-enforcement strategies, and thus, a more secure approach in protecting the applications from unauthorized use than copy protection.
