The Android operating system provides a number of useful services that applications can leverage. Many of these services are designed to allow your application to function within the mobile system in ways beyond just interacting briefly with a user. Applications can schedule themselves for alarms, run background services, and send messages to each other; all of which allows an Android application to integrate to the fullest extent with the mobile device. In addition, Android provides a set of standard interfaces designed to expose all the data collected by its core applications to your software. Through these interfaces, any application may integrate with, add to, and improve upon the core functionality of the platform, thereby enhancing the experience for the user.
