我试图通过AsyncTask使用HttpUrlConnection将网页加载到WebView中更加聪明。
以前我使用过WebView＆＃39; .loadurl()
我已经使用http://www.google.co.uk进行了测试，这似乎工作正常。
我从日志中得到了下面的输出，但是我无法确定加载这个特定页面的实际问题是什么。
我无法想象的是它为什么谈论支持或不支持的音频/视频编解码器。网页上没有这些内容。
将HTML加载到webview中时，我使用：
view.loadData(result, "text/html; charset=UTF-8", null);
抱歉这么直率的问题。

此问题归结为网页中的HTML不足。
包含<!DOCTYPE HTML>已解决此问题。 Logcat错误的相关性仍然未知
导致这种情况的另一个问题是使用风格和相对路径。 javascript资源。我有一个webview指向的iframe。由于我直接将HTML加载到视图中，因此视图不知道在哪里查找资源。我想虽然使用loadDataWithBaseUrl()会解决这个问题。但是，这没有。
作为修复，我必须在HTML页面上将所有相对路径更改为静态。

请尝试使用此功能。
webView.loadDataWithBaseURL("",result,"text/html", "UTF-8","");
