Answer 1

Try making these changes:

    SharedPreferences prefs = getSharedPreferences(
                    AppConstants.LOGIN_PREFS, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = prefs.edit();
    editor.clear();
    editor.commit();

    Intent intent = new Intent(getApplicationContext(), FirPageflipMainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(intent);

    this.finish();

Hope this helps.

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

public static void resetsetSharedPreferences(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 = new Intent(getApplicationContext(), FirPageflipMainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); 
    startActivity(intent);
