I try to connect to the service but I can not I can start the service it lansa the notification but does not bind when I call bindservice
I already added the request foregraud service and already moved the startSevice to oncreate I took as a basis the documentation of android I presiso learn how to solve this because the conponent is indicated in cases as music players and I believe thatThis will almetar my knowledge obs: as it is only a study I am not using the ViewModel
