Android中的服务与线程 [英] Service vs Thread in Android

问题描述

我正在寻找应在android applicaton中使用的服务.

I am looking for what service should be used in android applicaton.

文档说

服务是可以在后台执行长时间运行的操作且不提供用户界面的应用程序组件.

A Service is an application component that can perform long-running operations in the background and does not provide a user interface.

我已阅读此线程应用程序线程与服务线程，说相同的服务是用于在后台运行操作.

I have read this thread Application threads vs Service threads that saying same services are for running operation in background.

但是这里也可以使用Thread来完成.它们之间以及您应在何处使用它们之间的任何差异

But here this can be done using Thread also. Any difference between them and where you should use them

推荐答案

服务旨在独立于Activity运行任务，它允许您在后台运行任何任务.它运行在主UI线程上，因此当您要执行任何网络或繁重的操作时，必须在其中使用Thread.

A Service is meant to run your task independently of the Activity, it allows you to run any task in background. This run on the main UI thread so when you want to perform any network or heavy load operation then you have to use the Thread there.

示例:假设您想每天在后台备份即时消息，然后在这里使用Service.

Example : Suppose you want to take backup of your instant messages daily in the background then here you would use the Service.

Threads用于在其自己的线程而不是主UI线程中运行任务.如果您想进行一些繁重的网络操作(例如，将字节连续发送到服务器)，并且与Android组件相关联，则可以使用该功能.当您的组件销毁是谁启动的，那么您也应该停止它.

Threads is for run your task in its own thread instead of main UI thread. You would use when you want to do some heavy network operation like sending bytes to the server continuously, and it is associated with the Android components. When your component destroy who started this then you should have stop it also.

示例:出于某种目的，您正在使用Activity中的Thread，当您的Activity销毁时，最好将其停止.

Example : You are using the Thread in the Activity for some purpose, it is good practice to stop it when your activity destroy.
