ListPreference + v1.2.4 bug

[dimkinware]

Hello, I found a bug using v1.2.4 wih Preference dialog.
After changing language from selecting it from ListPreference dialog activity is recreated but language of the UI stays previous.
As I understand the reason is that in this case method Activity.getResources() is being called before Activity.attachBaseContext().
So LocalizationActivityDelegate.getResources() method change language in Resources object, then in subsequent attachBaseContext() method call next condition is not met:
if (!baseLocale.toString().equals(currentLocale.toString(), ignoreCase = true)) {

100% reproducing on Android 10 Pixel 2
v1.2.3 works fine.

To reproduce add next code in sample application:
SettingsActivity.java

package com.akexorcist.localizationapp.settingsactivity;

import android.os.Bundle;
import android.preference.PreferenceFragment;

import com.akexorcist.localizationactivity.ui.LocalizationActivity;
import com.akexorcist.localizationapp.R;

public class SettingsActivity extends LocalizationActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.settings_activity);
        getFragmentManager().beginTransaction().replace(R.id.main_content, new GeneralPreferenceFragment()).commit();
    }

    public static class GeneralPreferenceFragment extends PreferenceFragment {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.settings);
            setHasOptionsMenu(false);
            findPreference("language").setOnPreferenceChangeListener((preference, newValue) -> {
                String lang = newValue.toString();
                ((LocalizationActivity)getActivity()).setLanguage(lang);
                return true;
            });
        }
    }
}
