MAIN,INSIDE,SEAT,FOOD,WAIT
I have tried many different ways, but when I press finish in the wait activity, the time is not reset. I want to handle the clock when in Seat, Food, Wait running as the same clock when returning or continuing, the clock still runs correctly. When pressing finish, or when returning from Seat to Inside, the clock must be reset. For example, if the user exits the application while booking a ticket, the time will be erased, returning to 10 minutes.
