Answer 1

Yuu can clear the SharedPreference on Logout which you have set during login.
OnClick of Logout:

SharedPreferences sf = getSharedPreferences("UserLogin", MODE_WORLD_WRITEABLE);
            SharedPreferences.Editor edt = sf.edit();
            edt.putString("UserName", "");
            edt.putString("PassWord", "");
            edt.commit();

Hope this will help you…
