Xamarin在启动后在Android上形成应用程序崩溃（适用于首次安装）。
我第一次启动时请求登录并保存凭据。在第二次启动时，我使用这些凭据，自动登录，然后启动主表单。如果我每次都更改我的代码以请求登录（App.cs创建一个表单而不是崩溃时我触发登录对象，当它返回时，我在应用程序的回调中在UI线程上创建下一个表单。 CS）
它在我的代码之外崩溃了。我不知道如何查看导致崩溃的原因（它不会将异常抛回我的C＃代码）。
当我进行网络请求时，通常在我将cookie添加到标题
时失败通常在第三行，有时在第四行失败
var cc = new CookieContainer();
Cookie myCookie = new Cookie("MyCookie", sessionToken);
cc.Add(webRequest.RequestUri, myCookie);
webRequest.CookieContainer = cc;
此代码对我的主表单进行回调，如果重要，则会在事件中触发。
我确实查看了Android日志，并没有看到任何明显的信息。我将在下面复制。
有什么想法吗？我不知道如何调试它。
