Services are given a high priority by the Android system and are typically among the last to be terminated in order to free up resources.

== Intent Service ==

In terms of implementing the communication between a client and a bound service, the recommended technique depends on whether the client and service reside in the same or different processes and whether or not the service is private to the client. Local communication can be achieved by extending the Binder class and returning an instance from the onBind() method. Interprocess communication, on the other hand, requires Messenger and Handler implementation. Details of both of these approaches will be covered in later chapters.

The colon prefix indicates that the new process is private to the local application. If the process name begins with a lower case letter instead of a colon, however, the process will be global and available for use by other components.
