Localization strings not shown properly

I have an app we need to translate to several languages. So, I made values-en, values-pt, etc. One of the languages is turkish. So, I made my folder values-tr, and inside that, strings.xml file. Everything goes ok, except for one particular Activity. The strings that appear there are the ones in spanish (the default language in our app). BUT, if I change to another language (say, russian) and back to turkish, the strings are shown ok.
TextView mTitle = toolbarTop.findViewById(R.id.toolbar_title);
mTitle.setText(getString(R.string.mapproviders));
(In the strings.xml in values-tr):
<string name="mapproviders">Tedarikçi Haritası</string>
It works ok for other languages, it only fails in turkish and in that particular Activity.
Anyone has faced a similar problem?
UPDATE:
This is the way I am changing Locale:
public static void changeLang(String lang, Context ctx) {
Configuration config = ctx.getResources().getConfiguration();
if (!"".equals(lang) && !config.locale.getLanguage().equals(lang)) {
Locale locale = new Locale(lang);
Locale.setDefault(locale);
Configuration conf = new Configuration(config);
conf.locale = locale;
ctx.getResources().updateConfiguration(conf, ctx.getResources().getDisplayMetrics());
}
}

Multi-lingual Android - String values not being adapted to the change

I am adding a new feature to an android application, that enables the users to switch between two languages.
So far to test out the change of Locale I have been using the following piece of code in one of my Activities.
Locale myLocale = new Locale("ru");
Locale.setDefault(myLocale);
Resources res = this.getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
Locale current = getResources().getConfiguration().locale;
if (current.getLanguage().equals(myLocale.getLanguage())){
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
conf.setLocale(myLocale);
createConfigurationContext(conf);
recreate();
}else{
conf.locale = myLocale;
res.updateConfiguration(conf, res.getDisplayMetrics());
recreate();
}
}
setContentView(R.layout.activity_main);
The reason for checking the Version Code is that createConfigurationContext() requires API Level 17 and I'm using API Level 16. So this conditional lets me use the deprecated updateConfiguration() and also the createConfigurationContext().
I have also created the strings.xml for the relevant language and added a few values for testing.
What has been achieved so far is that the Dates are being shown in the translated language, so that tells me that the Locale has actually been changed to the correct one. Other strings that are supposedly taken from strings.xml (ru) aren't changing at all.
Are strings with multiple translations called in a different way from the layout xmls (See code below)? or maybe my structure isn't right?
android:text="#string/upcoming_title"

After posting the question I kept trying some stuff, and decided to try to add the following answer from another post:

This worked as expected.

device locale is set to en_us after clearing app data

I have a localized string resource A. I noticed that after I clear app data/cache (under setting), and open my activity (which belongs to that app), I always see resource A in en locale regardless of the current device language. If I go to setting again, change device language manually to whatever, and go back to my activity, then resource A is localized properly again.
I wondering why locale is set to default after app data/cache is cleared and is there a way to fix this? Thanks.

This is a hacky solution but you could set the locale in the launcher activity like this:
Configuration config = res.getConfiguration();
Configuration configuration = new Configuration();
config.locale = config.locale;
getBaseContext().getResources().updateConfiguration(configuration,
getBaseContext().getResources().getDisplayMetrics());
You can also check the device locale to be absolutely sure that the device locale has changed.

Displaying Arabic strings in Arcgis in Android (or installing

I have been spending the last few hours trying to figure out why my Arabic strings are not appearing on the ArcGis map.
The rest of the app is happily displaying Arabic (included the map "callout"). I thought it might have something to do with:
TextSymbol textSymbol = new TextSymbol(22, name, Color.BLACK);
Where name is something like:
name: المدينة المنورة
Finally, I found a single line in the sparse ArcGis Android documentation:
"The language used by the app is determined by your device's language setting."
I have been setting the localization in the app explicitly with:
private void setArabic() {
Resources res = getResources();
// Change locale settings in the app.
DisplayMetrics dm = res.getDisplayMetrics();
android.content.res.Configuration conf = res.getConfiguration();
conf.locale = new Locale("ar");
res.updateConfiguration(conf, dm);
}
The ArcGis documentation seems to suggest that the app localization is ignored and Arabic needs to be set on the phone settings.
If this is true, I need to determine the standard way to do this and the user's of the app will need to do the same.
The Play Store has hundreds of localization apps that say they will add Arabic but is there a way to do this using Google code rather than untrusted 3rd parties?

android: reflect UI language change on the on-the-fly without reload/restarting app

I have a setting in my app that allows user to select different localization (language), ie Chinese, German, etc.
What i would like to do is that once the user makes their choice, to immediately update the layout with strings in the currently selected language. Of course, i want the lang change propagated to ALL current activities, without reloading the app.
I found this (havent tried yet), but was wondering if there is a cleaner way of doing it.

Gracias

I also had this issue.I used the code below and then it changed the language without refreshing the activity
public void setLocale(String lang) {
myLocale = new Locale(lang);
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = myLocale;
res.updateConfiguration(conf, dm);
onConfigurationChanged(conf);
/*Intent refresh = new Intent(this, AndroidLocalize.class);
startActivity(refresh);*/
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
// refresh your views here
lblLang.setText(R.string.langselection);
super.onConfigurationChanged(newConfig);
}
I hope it would help you.......

There are some steps that you should implement
First, you need to change the locale of your configuration
Resources resources = context.getResources();
Configuration configuration = resources.getConfiguration();
configuration.locale = new Locale(language);
resources.updateConfiguration(configuration, resources.getDisplayMetrics());
Second, if you want your changes to apply directly to the layout that is visible, you either can update the views directly or you can just call activity.recreate() to restart the current activity.
And also you have to persist your changes because after user closes your application then you would lose the language change.
I explained more detailed solution on my blog post Change Language Programmatically in Android
Basically, you just call LocaleHelper.onCreate() on your application class and if you want to change locale on the fly you can call LocaleHelper.setLocale()
