所以我按照这篇文章的指示，我仍然无法让我的应用程序打开应用程序内的链接。

我做了很多研究。请记住，我对开发 android 非常陌生。谁能帮我？

如果有人单击链接（例如：styleonem.co/about）以转到该页面中的该 URL，我想做的是打开一个意图。

现在发生的事情是它打开了应用程序（很好！）但它永远不会在 Webview 中加载 url。我以为我已经把这一切都整理好了，但我已经连续数周搜索并尝试学习这个新的应用程序界面，但我仍然无法弄清楚。

下面是我的代码

AndroidManifest.xml：

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="co.styleonem.styleclothingco">
