Save the login state of the user

I want that application allows user to login for the first time. And then when user exit the application without logging out, user will be brought back to the same place or layout which comes after the login layout even if user start the application again. But if user logout from the application, user will be brought back to the main login screen.

From Launcher(splash screen)----->(App)Login page--->(App)Home screen

From Home app----->(App)Home screen

if click logout button

From Launcher(splash screen)----->(App)Login page--->(App)Home screen
