Unity Mobile Notifications推送问题

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;
