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 import android.content.Intent;
