Chrome 自定义标签在代理后失败

Question

我们有一个 Android 应用程序打开 Chrome 自定义选项卡以执行用户身份验证。 （下面列出了片段代码的剥离版本。）

当移动网络配置了代理地址：端口时，CCT 浏览器会显示一个弹出窗口以收集凭据。 这有3个问题：

1. 浏览器验证失败并崩溃
2. 弹出窗口很粗糙，与我们应用程序的对话框样式不匹配
3. 该应用程序通常已经拥有凭据，因此不需要对话框 - 一种方法应该允许在没有用户输入的情况下插入它们

我们的旧实现使用了具有onReceivedHttpAuthRequest()回调的 WebViewClient。 这将控制权交还给应用程序以显示它自己的对话框或直接提供凭据。

有没有办法对 CCT 做同样的事情？
