1.在部分机型点击通知弹窗进不去游戏

把这里改成自己的Activity

2.推送的时候没有横幅跟icon红点

主要是第一句话 注册的时候选项可以选择
defaultNotificationChannel =
new AndroidNotificationChannel(“default_channel”, “Default Channel”, “For Generic notifications”,Importance.High);

        defaultNotificationChannel =
            new AndroidNotificationChannel("default_channel", "Default Channel", "For Generic notifications",Importance.High);

        AndroidNotificationCenter.RegisterNotificationChannel(defaultNotificationChannel);

        AndroidNotificationCenter.NotificationReceivedCallback receivedNotificationHandler = delegate (AndroidNotificationIntentData data)
        {
            var msg = "Notification received : " + data.Id + "\n";
            msg += "\n Notification received: ";
            msg += "\n .Title: " + data.Notification.Title;
            msg += "\n .Body: " + data.Notification.Text;
            msg += "\n .Channel: " + data.Channel;
            Debug.Log(msg);
        };

        AndroidNotificationCenter.OnNotificationReceived += receivedNotificationHandler;
