Android的Service和Thread的区别

Service 是一种可在后台执行长时间运行操作而不提供界面的应用组件。

Android Service是组件，既不能说它是单独的进程也不能说它是单独的线程。
如果非要从通俗的语言层面来理解的话，姑且将其理解为对象。这个Service对象本身作为应用程序的一部分与它的调用者运行在相同的进程，当然如果指定了process则会运行到另外的进程。指定到其他进程的方法参加Service属性的"android:process"。

Android Service可以在后台运行，不需要给用户提供任何的界面。但是Service是默认运行在主线程的，不要以为可以直接把它放在后台作耗时操作，如果要做耗时操作还是需要在Service里另起线程的，否则你懂得，会阻塞主线程造成ANR。
Service是组件：默认运行在当前进程的主线程中的，如果需要执行耗时操作，记得在Service里创建新线程；
Service用来提高优先级：在后台场景下，Service的优先级是高于后台挂起的Activity的，也高于Activity所创建的线程。这样的话，在内存不足时，Service不会被优先杀死
