Can it possible to send push notification in Android TV through FCM? If it is possible then how can we send push notification through FCM and how to show it in Android TV?
回答1:
Yes, you can send notifications to Android TV, they will arrive to your service. Now that since there is no system tray, there is no default UI got them, so you need to do that yourself, you can't use the default behavior and you can't use notification manager.

I think notification will appear just as recommendations and not as "notification". One option will be using toasts or even a notification-android-tv
