Xamarin BroadcastReceiver即使在所有权限就绪后也未接收

我有一个问题，我的接收者没有收到。。。真奇怪

我觉得我读了stackoverflow上的每一篇文章，但没有任何效果

目标是安卓10，设备也运行安卓10，这是我的接收器

[BroadcastReceiver(Name = "com.meac.ReaderService.BootComplete", Enabled = true, Exported = true, Permission = "RECEIVE_BOOT_COMPLETED")]
    [IntentFilter(new[] { Intent.ActionBootCompleted })]
    public class BootComplete : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            
            string text = "Boot completed";
            ToastLength duration = ToastLength.Short;

            var toast = Toast.MakeText(context, text, duration);
            toast.Show();
        /*    if (intent.Action.Equals(Intent.ActionBootCompleted))
            {
                Intent s = new Intent(context, typeof(ReaderService));

                context.StartService(s);

                Intent s2 = new Intent(context, typeof(GuardService));

                context.StartService(s);

               // StartRDP(context);
            }*/
        }
    }

这是我的清单，应该包含所有需要的权限

我已手动启用“显示在其他应用上”权限

我今天已经花了6个小时，我完全迷路了

这将是100%愚蠢的事情

希望有人能理解这一点，能对此进行调查。谢谢。

通过在意向过滤器中添加类别修复了这一问题

[IntentFilter(actions: new[] { Intent.ActionBootCompleted }, Categories = new []{ Intent.CategoryDefault })]

你有没有在Android 8.0之前的旧版本上测试过你的接收器？在安卓8.0（API 26及以上）中，谷歌限制了用户不直接与应用交互时应用程序的功能。检查限制：
