Project description
There is a ready-made client application that plays videos through the Youtube API. I would like to add the notification display function to the bar status when adding a new video to the channel / playlist. I am a beginner, the application was written by myself (thanks to video lessons), and there is not enough brains on notification.
So the task is not just to make a notification, but to explain to me the principle and show on a real application, so that in the future I do it for myself.
