thank you very much for the replies, I'll digg up on the SharedPreferences. Sarwar you are right, I want the user to be able to use the application in any device with his email. I would just like him not to perform login every time. Basically like danH mentioned about a browser. Lets say a website like facebook. If u register, login and save password it will recognize the user.. otherwise the user can logout.
Anyway thanks for the messages, I'll try to find some code to get me started on the client side.
