可运行在服务于一个主线程工作 [英] Runnable in service working in a main thread

问题描述

我在机器人编程新。
试图得到一些有用的数据从网络JSON（网络任务）中设置并解析它。
所以我选择这个服务，为使后台作业。如何正确安装重复任务Handler.postDelayed（可运行，间隔）不在主线程？

I'm new in android programming. Trying to get some useful data set from web json(network task) and parse it. So i choose for this Service, for making background job. How do i properly install repeated task with Handler.postDelayed(runnable, interval) not in the main thread?

请帮我算出这个？

推荐答案

IntentService 意图在后台工作线程运行。

IntentService intents run on a background worker thread.

不过，你似乎是发布可运行做网络操作，以处理这很可能是在UI线程上，因为你得到 NetworkOnMainThreadException 。

However, you seem to be posting a runnable doing network operations to a handler which is likely on the UI thread since you're getting NetworkOnMainThreadException.

这说明了问题。请澄清你想要完成，所以我们可以提出一个更好的办法是什么。

This explains the problem. Please clarify what you're trying to accomplish so we can suggest a better approach.
