I'm asking a question with a translator, so I'm sorry for the spelling. I am creating a music player application and notifications for it. I searched for a long time how to add a slider to the notification and such an error came out that when I pause the player and turn it on again, the slider in the notification stops moving, otherwise everything works. Thank you in advance for your help! Задаю вопрос с переводчиком так что за орфографию извините. Я создаю приложение музыкальный плеер а также для него уведомления долго рыскал как добавить к уведомлению ползунок и вылезла такая ошибка что когда я ставлю плеер на паузу и снова его включаю ползунок в уведомлении перестает двигаться в остальном все работает. Заранее благодарю за помощь!
