Solution 1: I Solved it i Added a MyContextWrapper Class import android.content.Context; import android.content.res.Configuration; import android.content.res.Resources; import android.os.Build; import android.os.LocaleList;

import java.util.Locale;

public class ContextWrapper extends android.content.ContextWrapper {

public ContextWrapper(Context base) {
    super(base);
}

public static ContextWrapper wrap(Context context, Locale newLocale) {

    Resources res = context.getResources();
    Configuration configuration = res.getConfiguration();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        configuration.setLocale(newLocale);

        LocaleList localeList = new LocaleList(newLocale);
        LocaleList.setDefault(localeList);
        configuration.setLocales(localeList);

        context = context.createConfigurationContext(configuration);

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        configuration.setLocale(newLocale);
        context = context.createConfigurationContext(configuration);

    } else {
        configuration.locale = newLocale;
        res.updateConfiguration(configuration, res.getDisplayMetrics());
    }

    return new ContextWrapper(context);
}

}

and then I Create a Base Activity and Added Locale there which you were saving in shared preferences and pass it at runtime. import android.content.Context; import android.content.SharedPreferences; import android.os.Bundle; import android.preference.PreferenceManager; import android.support.v7.app.AppCompatActivity;

import com.appabilities.occasions.android.rosetta.ContextWrapper;

import java.util.Locale;

public abstract class BaseActivity extends AppCompatActivity {

SharedPreferences mSharedPreferences;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
  
}



@Override
protected void attachBaseContext(Context newBase) {
    mSharedPreferences= PreferenceManager.getDefaultSharedPreferences(newBase);
    Locale locale = new Locale(mSharedPreferences.getString("user_preferred_language", "en"));
    Context context = ContextWrapper.wrap(newBase, locale);
    super.attachBaseContext(context);
}

}

these two files need to be added. and boom solved

Solution 2:

A Locale Helper Class can also help with it import android.annotation.TargetApi; import android.content.Context; import android.content.ContextWrapper; import android.content.res.Configuration; import android.os.Build;

import java.util.Locale;

public class LocaleHelper extends ContextWrapper {

  public LocaleHelper(Context base) { super(base); }

  @SuppressWarnings("deprecation") public static ContextWrapper wrap(Context context, String language) { Configuration config = context.getResources().getConfiguration(); if (!language.equals("")) { Locale locale = new Locale(language); Locale.setDefault(locale); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { setSystemLocale(config, locale); } else { setSystemLocaleLegacy(config, locale); } if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) { config.setLayoutDirection(locale); context = context.createConfigurationContext(config); } else { context.getResources().updateConfiguration(config, context.getResources().getDisplayMetrics()); } } return new LocaleHelper(context); }

  @SuppressWarnings("deprecation") public static Locale getSystemLocaleLegacy(Configuration config) { return config.locale; }

  @TargetApi(Build.VERSION_CODES.N) public static Locale getSystemLocale(Configuration config) { return config.getLocales().get(0); }

  @SuppressWarnings("deprecation") public static void setSystemLocaleLegacy(Configuration config, Locale locale) { config.locale = locale; }

  @TargetApi(Build.VERSION_CODES.N) public static void setSystemLocale(Configuration config, Locale locale) { config.setLocale(locale); } }

and Add this as a Base Activity

import android.content.Context; import android.content.SharedPreferences; import android.os.Bundle; import android.preference.PreferenceManager; import android.support.v7.app.AppCompatActivity;

import com.ahmedjazzar.rosetta.ContextWrapper;

import java.util.Locale;

public abstract class BaseActivity extends AppCompatActivity { SharedPreferences mSharedPreferences;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

}

protected void attachBaseContext(Context newBase) {
    mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(newBase);
    Context context = LocaleHelper.wrap(newBase, mSharedPreferences.getString("user_preferred_language", "en"));
    super.attachBaseContext(context);
}

}
