Localization strings not shown properly - android

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.

make multi language android application

I created multi language (English, Russian, Uzbek) app. I put 4 string resoureses in 4 folders (values, values-en, values-ru, values-uz) as docs. When I change app language updates resourses configuration in App Controller like below:
Settings.LANGUAGE = prefs.getString(User.LANG, Settings.RUSSIAN);
Locale locale = new Locale(Settings.LANGUAGE);
Locale.setDefault(locale);
Configuration configuration = new Configuration();
configuration.locale = locale;
getBaseContext().getResources().updateConfiguration(configuration,
getBaseContext().getResources().getDisplayMetrics());
After that App restarts by calling App controller's method like below:
public void reStart() {
Intent i = getBaseContext().getPackageManager()
.getLaunchIntentForPackage(getBaseContext().getPackageName());
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
}
After them It works well almost all devises. But on Samsung Galaxy S6 (SM-G920F), it works as crazy. Some words are in english and others are in Uzbek and ets.
So, How to fix this error? isn't the concepts of "Supporting Different Languages" supported by (applicable to) all devices?
By the way, I have checked that all resources are given in corresponding languages (as shown in attached image):
From my observations, weird behaviour was affecting only Activity titles, and I found that I was setting translations of activity titles in Manifest file. Only these translations were misbehaving. All other dynamically set translations were working fine.
So, to fix the problem, I removed all activity labels from Manifest file, then set activity titles in onCreate method as below:
getSupportActionBar().setTitle(R.string.title_activity_followers);
Problem solved.

Android time picker dialog language changed from Locale setting

I am using two languages in app, English and Swedish.
I have used below code for managing language change by user,
final Locale locale;
if (languagecode == 1)
{
locale = new Locale("sv");
}
else
{
locale = new Locale("en");
}
Locale.setDefault(locale);
final Configuration config = new Configuration();
config.locale = locale;
mContext.getResources().updateConfiguration(config, mContext.getResources().getDisplayMetrics());
Now when I show Time picker dialog with Swedish language selected as default, it shows swedish translation in dialog, it also changes the AM/PM text. Is there any way to put custom text over there or it comes as system default? Please check the image below for reference. Thanx.
There is a tutorial here for customizing time pickers. You can define the title for example as a string resource and then create separate resource folders for translations (more info on localization here).

Issue with setting locale within app

In my app, i am asking for language, can be either English or German. The selected language and its iso code is saved into preferences. On the basis of selected language i need to change all the texts into corresponding language.
For this, i have created res/values and res/values-de; each folder containing a strings.xml file. Issues are:
1) I am opening camera as well as a screen using opengl. After navigating via both of them, the texts does not change completely into german(if was chosen). Some text values change into German, rest not even on the same page.
2) Even without going through camera and opengl screens, the results are not achieved 100% always but gives a better result always as compared to case 1.
My implementations:
1) in onResume() of splash screen, i am changing locale based on preferences with the help of config.locale().
2) in manifest file, each activity is set with activity:configChanges="locale".
3) in camera activity and opengl activity, onConfigurationChanged() is overridden in which i am again setting locale as per preferences.
please guide how to solve the locale issue.
Check Point 1:
Partial updation of resources. Make sure you have resources named correctly in all your languages.
Also, you can give this code a try. It is how i update locale of my app:
public void updateLocale(String language) {
Locale myLocale = new Locale(language);
Locale.setDefault(myLocale);
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = myLocale;
res.updateConfiguration(conf, dm);
}
Let me know if it helps !
I believe you need to add something to your AndroidManifest file indicating locale change. Here is an example: http://android.programmerguru.com/android-localization-at-runtime/
I had a similar problem with my app. App has force language changing option between Turkish and English. If my device language is English and if I use the app in Turkish, I can easily convert the language with the code below:
public void setAppLanguage(String languageCode) {
String countryCode;
if (languageCode.equals("tr")){
countryCode = "TR";
}else{
countryCode = "US";
}
Locale locale = new Locale(languageCode, countryCode);
Locale.setDefault(locale);
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = locale;
res.updateConfiguration(conf, dm);
loginPrefsEditor.putString("uLang",languageCode);
loginPrefsEditor.apply();
}
However, when I open the camera and return from it, app language changes back to default phone language. App kills my activity when I open the camera. After return from the camera, it refreshes everything. So in order to solve this problem, I put my force change language method in onResume() method of every activity.
By doing this I would be able to solve this issue.

Localize Android application so I can switch locale inside app

How do I localize application so it uses specific locale regardless of what locale set on device? I want make it possible for users to set language of their choice.
So far I have code like this in my Application class:
#Override
public void onCreate()
{
//Set locale
String l = Preferences.getLocale(getApplicationContext());
if (!l.equals(""))
{
Locale locale = new Locale(l);
Locale.setDefault(locale);
Configuration config = getBaseContext().getResources().getConfiguration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(
config, getBaseContext().getResources().getDisplayMetrics());
}
LogData.InsertMessage(getApplicationContext(), "Application started");
}
Problem that I have is that it seems like I display in set locale just fine (TextViews)
But Menu captions and toasts will fall to default locale.
Is there any 1-2-3 on how to get it working properly? I uses 2.2 version
This post explains how to force localization in your app.
Ok, I figured why I had this problem.. I needed to override onConfigurationChanged in my application class. That is much more elegant solution than to specify locale on each Activity.
