cn1 - 网络视图不工作
cn1 - webview not working
在我的 cn1 应用程序中，我有一些我想要显示的内容，这些内容已经被格式化为 HTML，所以我认为只停留在 WebView 中而不是尝试解析它并创建单独的内容是最有意义的每个段落的cn1组件等
问题是我无法说服该应用实际显示它。
这是我的代码：
WebBrowser web = new WebBrowser();
web.setURL(StateMachine.URL_PREFIX + "/api/article_body.php?articleId=" + (String)map.get("id"));
mac.findArticleBodyContainer(f).addComponent(BorderLayout.CENTER, web);
form.revalidate();
这是我在 Android 设备上打开应用程序时的 logcat 输出（运行 Marshmallow，之前使用 Lollipop 它也不起作用，但我没有来自那个的日志）：

我还没有在任何其他 OS 上尝试过，尽管我在另一个 Android 设备（也是 Marshmallow）上遇到了同样的问题。
注意： SO 问题有答案，但对于母语 Android。我没有看到以相同方式从 cn1 访问 webview 设置的方法。

我将 HTML 内容移动到应用程序，并从本地文件加载它。我从模拟器中没有收到任何错误，但没有内容显示。在我的 Android 设备上，没有任何显示，这是 Logcat:
