Android - 在后台运行 - 服务vs.标准的java类 [英] Android - Run in background - Service vs. standard java class

问题描述

在Android中，如果我想做一些背景工作，

In Android, if I want to do some background work, what is the difference between

创建服务来完成工作，让Activity启动服务
VS.
创建一个标准的java类来完成这个工作，并让Activity创建一个类的对象并调用方法，在单独的线程中进行工作。

Creating a Service to do the work, and having the Activity start the Service VS. Creating a standard java class to do the work, and having the Activity create an object of the class and invoke methods, to do the work in separate thread.

推荐答案

做你自己的线程是过度，有解决方案，所以你不必担心并发的硬性部分​​。请查看 AsyncTask 或 IntentService 。如果你去服务，请记住，你的服务可以在任何时候被杀。

Doing your own threads is overkill, there are solutions for this, so you don't have to worry about the hard parts of concurrency. Have a look at AsyncTask or IntentService. If you go for a service please keep in mind that your service can be killed at any time.
