Implementing Multiple language in my app. It changes layout direction but not getting value from second language string.xml

Question

package com.zeugmasolutions.localehelper

import android.annotation.SuppressLint
import android.app.Application
import android.content.Context
import android.content.SharedPreferences
import android.os.Build
import java.util.Locale

object LocaleHelper {
    private const val SELECTED_LANGUAGE = "Locale.Helper.Selected.Language"
    private const val SELECTED_COUNTRY = "Locale.Helper.Selected.Country"
    private var initialized = false

    /**
     * Returns the system [Locale]
     */
    @SuppressLint("ConstantLocale")
    val systemLocale: Locale = Locale.getDefault()

    /**
     * Attach the selected or default [Locale] to the [context]
     */
    fun onAttach(context: Context): Context {
        if (!initialized) {
            Locale.setDefault(load(context))
            initialized = true
        }
        return updateContextResources(context, Locale.getDefault())
    }

    /**
     * Gets the currently saved [Locale] from [SharedPreferences] or returns [Locale.getDefault]
     */
    fun getLocale(context: Context): Locale = load(context)

    /**
     * Sets [locale] for [context] and persist the selection in [SharedPreferences]
     */
    fun setLocale(context: Context, locale: Locale): Context {
        persist(context, locale)
        Locale.setDefault(locale)
        return updateContextResources(context, locale)
    }

    /**
     * Returns if the given [locale] is a Right-To-Left language
     */
    fun isRTL(locale: Locale): Boolean = Locales.RTL.contains(locale.language)

    private fun getPreferences(context: Context): SharedPreferences =
        context.getSharedPreferences(LocaleHelper::class.java.name, Context.MODE_PRIVATE)

    private fun persist(context: Context, locale: Locale?) {
        if (locale == null) return
        getPreferences(context).edit()
            .putString(SELECTED_LANGUAGE, locale.language)
            .putString(SELECTED_COUNTRY, locale.country)
            .apply()
    }

    private fun load(context: Context): Locale {
        val preferences = getPreferences(context)
        val default = Locale.getDefault()
        val language = preferences.getString(SELECTED_LANGUAGE, default.language) ?: return default
        val country = preferences.getString(SELECTED_COUNTRY, default.country) ?: return default
        return Locale(language, country)
    }

    private fun updateContextResources(context: Context, locale: Locale): Context {
        if (context.currentLocale == locale && context is Application) {
            return context
        }

        val resources = context.resources
        val configuration = resources.configuration
        configuration.setCurrentLocale(locale)

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            configuration.setLayoutDirection(locale)
        }

        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            context.createConfigurationContext(configuration)
        } else {
            @Suppress("DEPRECATION")
            resources.updateConfiguration(configuration, resources.displayMetrics)
            context
        }
    }
}

I have implement using this link https://github.com/zeugma-solutions/locale-helper-android and also done it by customised code but result is same. I also recreating activity.

Result: Language changed in Locale defaults and directions of layout as well but strings are coming from default string.xml not second language string.xml. Expected results : Should show selected language texts
