can i know how you are using SharedPreferences to save the data, how you are retrieving that. — Ankur1994a, Feb 27 '16 at 05:38
why are you passing null in this.getSharedPreferences("Login",null); when getting values. use 0 instead of it. 0 is use for getting SharedPreferances in private mode. — Ankur1994a, Feb 27 '16 at 05:49

In your case, You can go with SharedPreferences. Your data will be stored in key-value pair. And also, it is persistent storage.
