此问题在此处已有答案：

How can I request permission from the user for autostart and for Battery saver(No restrictions) in Xamarin.Forms android?（1个答案）
三个月前关门了。
我需要检查xiaomi上的应用程序设置中的框，它的工作原理华为上出现错误。
我的验证码：

try
            {
                Intent intent = new Intent();
                intent.SetComponent("com.huawei.systemmanager", "com.huawei.systemmanager.appcontrol.activity.StartupAppControlActivity"); // huawei
                // intent.SetComponent(new ComponentName("com.miui.securitycenter", "com.miui.appmanager.ApplicationsDetailsActivity")); // xiaomy
                intent.PutExtra("package_name", PackageName);

                StartActivity(intent); 

            }
            catch (Exception anfe)
            {
            }

我的例外

这个应用程序可以自己打开这个页面，基本上这个问题都是华为手机上出现的，目前我正在写一个安卓的应用程序，但是xamarin允许你写iOS的代码，所以以后我也会在那里添加这样的功能。
