使用 webview 在 android 应用程序中加载 html 页面

Question

我有这个代码

webView.loadUrl("file:android_asset/index.html");

并且可以工作，但是当我在该页面内按下重定向按钮到其他页面时不起作用，并且发生了这个错误：

我该如何解决这个问题，有什么建议吗？

我想要做的是在资产文件夹应用程序中有一个 Web 应用程序来浏览 webview，并且只使用来自外部服务器的 php 文件。

对不起我的英语。

读取内容 Html 文件并使用它：

webView.loadDataWithBaseURL(null, *contentHtml* ,"text/html", "utf-8", null);
