This application implements a simple alarm function, and can also be alerted to the alarm clock when the program is closed. A problem is left here : If I close the program by applying itself, I can do what I mentioned above, but if I implement the application shutdown in the phone process management, the reminder doesn't work, and I'm puzzled I've closed the application itself and I can't see it in the p
