Instead of Toast message can we add a Dialog asking user Are you sure to exit ??

In most of apps I had seen toast message @meghalagrawal , I think it would be better as it will not break the app flow and in case of pressing back button mistakenly user will be bothered to close the dialog which could be quite annoying
