Solution 2:

Create a method resetsetSharedPreferences in your Utility class or Activity or Fragment

publicstaticvoidresetsetSharedPreferences(Context context,
                                                 String sharedPrefname) {
        SharedPreferences mPrefs = context.getSharedPreferences(sharedPrefname,
                Context.MODE_PRIVATE);
        mPrefs.edit().clear().commit();
    }

And then just call to this method during signout

resetsetSharedPreferences(getActivity().getApplicationContext(), AppConstants.LOGIN_PREFS);

 Intent intent = newIntent(getApplicationContext(), FirPageflipMainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); 
    startActivity(intent);
