 - _Foreground_ services: they are strictly related to the user's interaction (for example music playback), so it's harder for the system to kill them.
 - _Background_ services: they are not directly related to the user's activities, so they can be killed if more RAM is needed.
 - _Bound_ services: offers a client-server interface that allows components to interact with the service, send requests, receive results, and even do so across processes with interprocess communication (IPC).
+- _Intent_ services: An IntentService is meant to handle individual autonomous calls. Unlike a service, which can concurrently handle multiple calls, an IntentService is more like a work queue processor – work is queued up and an IntentService processes each job one at a time on a single worker thread. Typically, an IntentService is not bound to an Activity or a Fragment.
