如何以编程方式从状态栏 android 清除 firebase 推送通知

Question

I can clear the notification that is pushed from the app with this code

val notificationIds: MutableList<Int> = ArrayList()
val notificationManager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationIds.forEach {
    notificationManager.cancel(it)
}

it works with when I save notification Id at every notify
but now I didn't have firebase notification id

Answer 1

Better to Delete All Notifications rather to keep notification id

NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.cancelAll();

Answer 2

For this, you need to send data messages from Firebase and with that you can create notification with id manually. Hence, you would be able to cancel/clear notification.
