How to clear activity stack in android

Question

I have the following application stream in an android app,

Login-> Home-> screen1-> screen2-> screen3-> screen4-> logout

On screen4, I have a logout button that allows the user to exit the application and re-enter the system. When you re-enter the application, the previous data is still displayed. Is there a way to launch the application when the user exits the application?

NOTE: in all of the above launch start modes, the value is set to "single task",

Regards, Sam.
