после закрытия стриминговой платформы (будь то спотифай или что-то другое) происходит краш (как только getMediaSessions() возвращает null) в нативном коде и после чего жвм падает, перепробывал всё что можно и нельзя, хэшировал текстуру, делал проверки и защиту на нулл, один хер он крашит, в итоге психанул и переписал MediaPlayer с более улучшенной логикой работы onTick, но проблема осталась прежней, надеюсь на помощь знатоков с форума

вы тут хоть всем скопом пытайтесь, но не зафиксите
