本文讨论了在Android应用中使用服务来进行长时间运行的操作的重要性。服务进程的优先级高于背景线程，确保即使在触发活动不再存在时，关键任务也能继续执行。文章通过播放背景音乐和上传图片到网站的例子说明了这一点，并强调了广播接收器也应该使用服务来处理耗时的任务。

Because a process running a service is ranked higher than one with background activities, an activity that initiates a long-running operation might do well to start a service for that operation, rather than simply spawn a thread — particularly if the operation will likely outlast the activity. Examples of this are playing music in the background and uploading a picture taken by the camera to a web site. Using a service guarantees that the operation will have at least "service process" priority, regardless of what happens to the activity. As noted in the Broadcast receiver lifecycle section earlier, this is the same reason that broadcast receivers should employ services rather than simply put time-consuming operations in a thread.
只有service 的进程比只有分线程的process 优先级高持续时间有可能更长。
