Question

I have made an android app which working fine. I implemented the Login functionality in it. Can anyone guide me how to store the login credentials of the user so that the user does not have to login everytime he/she starts the app and when user logout then clear the stored login information.

Actually i want that user does not have to enter login information everytime when he/she starts the app.How can i do this?

Answer 1

Store value use sharepreference. i am pasting code here..use it.

Create Share Preference:

SharedPreferences sp=getSharedPreferences("Login", MODE_PRIVATE);
SharedPreferences.Editor Ed=sp.edit();
Ed.putString("Unm",Value );              
Ed.putString("Psw",Value);   
Ed.commit();

Get Value from Share preference:

SharedPreferences sp1=this.getSharedPreferences("Login", MODE_PRIVATE);

String unm=sp1.getString("Unm", null);       
String pass = sp1.getString("Psw", null);

When user logout then you can set null value into sharedpreference.
