Flutter: Web View Secure Origin

由 六月ゝ 毕业季﹏ 提交于 2020-01-09 11:57:16
问题 I am getting an error with Flutter Webview (webview_flutter: ^0.1.2) when loading a Youtube Video, (though I initially thought its related to content security issue,) it seems to be an issue with secure origin on HTTPS. On browser this is usually mitigated by moving to HTTPS domain, looking for a way to solve this on Mobile Container( child: WebView( initialUrl: Uri.dataFromString( '<html>' '<meta http-equiv="Content-Security-Policy" content="default-src * gap:; script-src * \'unsafe-inline\'

WebView性能、体验分析与优化

由 我怕爱的太早我们不能终老 提交于 2020-01-09 01:03:26
在App开发中，内嵌WebView始终占有着一席之地。它能以较低的成本实现Android、iOS和Web的复用，也可以冠冕堂皇的突破苹果对热更新的封锁。 然而便利性的同时，WebView的性能体验却备受质疑，导致很多客户端中需要动态更新等页面时不得不采用其他方案。 以发展的眼光来看，功能的动态加载以及三端的融合将会是大趋势。那么如何克服WebView固有的问题呢？我们将从性能、内存消耗、体验、安全几个维度，来系统的分析客户端默认WebView的问题，以及对应的优化方案。 性能 对于WebView的性能，给人最直观的莫过于：打开速度比native慢。 是的，当我们打开一个WebView页面，页面往往会慢吞吞的loading很久，若干秒后才出现你所需要看到的页面。 这是为什么呢？ 对于一个普通用户来讲，打开一个WebView通常会经历以下几个阶段： 交互无反馈 到达新的页面，页面白屏 页面基本框架出现，但是没有数据；页面处于loading状态 出现所需的数据 如果从程序上观察，WebView启动过程大概分为以下几个阶段： 如何缩短这些过程的时间，就成了优化WebView性能的关键。 接下来我们逐一分析各个阶段的耗时情况，以及需要注意的优化点。 WebView初始化 当App首次打开时，默认是并不初始化浏览器内核的；只有当创建WebView实例的时候，才会创建WebView的基础框架。

appium（六）H5页面

1、区分APP是H5还是native 　　（1）手机进入开发者模式，选择显示页面布局边界，native app中所有的控件都是独立的红框，而web H5是一个完整的大框，里面的可以操作的小控件不独立 　　（2）adb先连接模拟器，在电脑浏览器打开chrome://inspect使用inspect工具，如果能够在其中看到webview的显示，那么说明这个地方有个webview，是H5页面 。(如果需要inspect，需要翻墙下载一下devtools，否则会出现404) 如下面的两个webview就是H5页面 2、H5页面元素定位 　　（1）使用appium原生的安卓元素定位 　　如果H5页面在APP内，则Desired Capabilities的设置和启动APP一样，定位也同样使用appium元素的安卓元素定位，可以使用appium-desktop来查找网页元素 　　（2）使用selenium的网页元素定位 　　 如果H5页面是在浏览器中，则Desired Capabilities的设置和启动APP不同 ： 　　　　--1.如果使用Android原生的浏览器打开H5，则使用browserName="Browser" 代替appPackage和appActivity；在appium启动browser时，如果出现chromedriver不匹配的问题，先查看手机安卓的系统应 用中

Android WebView style background-color:transparent ignored on android 2.2

由 冷暖自知 提交于 2020-01-08 12:00:12
问题 I'm struggling to create a WebView with transparent background. webView.setBackgroundColor(0x00FFFFFF); webView.setBackgroundDrawable(myDrawable); Then I load a html page with <body style="background-color:transparent;" ... The background color of the WebView is transparent but as soon as the page is loaded, it's overwritten by a black background from the html page. This only happens on android 2.2, it works on android 2.1. So is there something to add in the html page code to make it really
