[英]Does a Web Worker run on the main ui android thread or a separate thread?
I have an OLD application for the Android that uses WebChromeClient 我有一个使用WebChromeClient的Android版旧应用程序
public class MyWebViewClient extends WebChromeClient
公共类MyWebViewClient扩展了WebChromeClient
to run a web page on the Android as an application . 作为应用程序在Android上运行网页。 The original intent was to keep the displays for apps (browser, ios, and android) identical .
最初的目的是使应用程序(浏览器,ios和android)的显示保持一致 。 As usually happens, the application grew more complicated over time (5 years) and a local web database is used to store state for faster startup.
通常,应用程序随着时间的推移(5年)变得越来越复杂,并且使用本地Web数据库存储状态以加快启动速度。
With the latest version of the Android Oreo OS, my app gets a ANR warning. 使用最新版本的Android Oreo OS,我的应用收到ANR警告。 I realize it is time to redesign but have a super tight schedule.
我意识到是时候重新设计了,但是时间表很紧。 If I move the initialization code (web database that uses callbacks (promises), ...) into a html 5 web worker, will that code run on a separate thread in Android application (other than the main ui thread?) Will this solve the ANR?
如果我将初始化代码(使用回调(承诺)的Web数据库,...)移到html 5 Web Worker中,那么该代码是否可以在Android应用程序中的单独线程(主ui线程以外的线程)上运行? ANR? Or do I have to totally redesign?
还是我必须完全重新设计?
Does a Web Worker run on the main ui android thread or a separate thread?
Web Worker是在ui主android线程上运行还是在单独的线程上运行? BTW - how about in the latest IOS, are web workers run on the main thread or separate thread?
顺便说一句-在最新的IOS中,Web Worker是在主线程上运行还是在单独的线程上运行?
Thanks in advance for your input. 预先感谢您的输入。
