I'd like to know what to name my folder for different languages. Where can I find the supported list of languages on Android?

Can you move the answer to your question to an answer to this post, and mark it as the selected answer? For others who have the same question, it will help for them to be able to see that there's a selected answer :) (BTW, it's totally fine to answer your own question). – Frasch 1/11, 2011 at 21:50

Yes, please edit this so you are asking a question in the question area like "What locales does Andriod support, and from what version did it support them? Does a list exist?", then provide the information as an answer. This would probably be handy to link to in the Tag Wiki. I'm making this CW so others can help turn it into a proper question, thanks for sharing :) – Tapp 2/11, 2011 at 2:28

If you installed the Extras in Android SDK Manager, then after installation, go to the \android-sdk\extras\android\support\v7\appcompat\res directory to see a list of locale [directories] supported by Android. Also, check this link. – Sammons 26/3, 2014 at 11:16

Define "support". You can use all three-letter language codes without problem (although there may be no interface by which to select that language). I've developed apps in Asturian (code ast) and there's no problem as of Android 5ish. Only some distributions let users select it, so I have a option in settings to always launch in X language which includes all my supported locales. – Calcutta 24/1, 2016 at 1:48

Here's the answer to the "how to name" part of the question from the Configuration qualifier names table: "The language is defined by a two-letter ISO 639-1 language code, optionally followed by a two letter ISO 3166-1-alpha-2 region code (preceded by lowercase 'r')." – Manakin 21/6, 2016 at 22:26

Original Answer :

As of Android 5.0, all languages in BCP 47 are available for application development (they may not necessarily be available for selection in a given device's system settings, though). When using ISO 639-1 codes, the resource folder has the format values-xx... where xx is the ISO-639-1 code.

When using BCP 47 tags, the resource folder is named values-b+xxx... where xxx is the three-letter language code.

*Note that Java uses several deprecated two-letter codes. The Hebrew (“he”) >language code is rewritten as “iw”, Indonesian (“id”) as “in”, and Yiddish (“yi”) as “ji”. This rewriting happens even if you construct your own Locale object, not just for instances returned by the various lookup methods. See also https://issuetracker.google.com/issues/36908826.

Is there any list, like that on developer.android.com? – Coonskin 18/11, 2013 at 7:17

The correct format for Android resource folder is not e.g. values-pt_PT but values-pt-rPT. Replace "_" by "-r". I had compilation error and finally looked at Android 4.0.1 source code to see the correct folder name. – Sadyesaechao 15/1, 2014 at 23:46

In fact, this is a mess. For example, spanish is not supported with "values-es" directory as it should (ISO-639-1 code is "es"), not even "value-es_ES". It only works with "values-sp" directory (and maybe other fancy forms based on "sp" code). My testing device is under Android 4.0.4, it may be fixed by now, but that is far later than 1.5 where support is expected with ISO-639-1 (or even BCP-47 by the way). – Suiter 14/2, 2017 at 8:57

don't support "fa" or "ar" for TextToSpeech class! Does anyone have a solution? – Wilderness 30/9, 2018 at 14:26

List of locales supported as of API 22 (Android 5.1). Obtained from a Nexus 5 with locale set to "English (United States)" (locale affects the DisplayName output).

for (Locale locale : Locale.getAvailableLocales()) {
    Log.d("LOCALES", locale.getLanguage() + "_" + locale.getCountry() + " [" + locale.getDisplayName() + "]");

This list is incorrect, as the codes are missing script subtags, there are duplicates, and the codes contain underscores where they shouldn't. Could you correct it? – Laurenalaurence 4/10, 2019 at 11:46

The best way to see the supported list is to start up the emulator in the latest version and open the "Custom Locale" app. This will list all of the supported languages and locales for that version of Android.

values-zh-rTW, on the other hand, compiles and works correctly :) – Marmolada 14/2, 2013 at 15:9

@androiddeveloper yes, Java uses iw, a deprecated code. Same with Yiddish (uses "ji" instead of "yi") and Indonesian (uses "in" instead of "id") (Source: wilsonmar.com/android_localization.htm#Localez) – Nailbiting 16/6, 2014 at 21:44

@Nailbiting I thought it's the opposite - that "he" is the deprecated one. Are you sure about it? – Tallu 16/6, 2014 at 21:46

@androiddeveloper yes, I recently took a look at the Google Calendar app's source code, translated to 44 languages. I've seen hebrew inside res/values-iw/strings.xml. Also there you can find a values-in folder (and not values-id) – Nailbiting 16/6, 2014 at 21:56

@Nailbiting I don't understand. Which one is the deprecated one? "he" or "iw" ? if it's "iw", how come Google Calendar uses it? According to my experience, "iw" is more popular and only old carriers' roms use "he" . Maybe this is the reason: code.google.com/p/android/issues/detail?id=3639 – Tallu 16/6, 2014 at 22:21

@androiddeveloper that's right, the reason is Google follows Java standard regarding this. Java uses the deprecated codes, so does Android. From the issue you mentioned (it seems a response from somebody at Google): you're correct that it's not a _language_ issue, but it is a _library_ issue. Sun's libraries have this behavior, so, for compatibility, we do too. if you look at the code for creating a Locale, you'll see we explicitly mangle "he" to "iw" for compatibility. a couple of other country codes receive the same treatment. – Nailbiting 16/6, 2014 at 23:4

I've just noticed this is in the official docs, too: developer.android.com/reference/java/util/Locale.html. 3rd paragraph: Note that Java uses several deprecated two-letter codes... – Nailbiting 16/6, 2014 at 23:21

@Nailbiting well I was sure it was the opposite. Why was it changed from "iw" to "he" anyway? also, I don't know if it happens today, but a few years ago, in order to support hebrew, I had to put the strings into both "values-he" and "values-iw", because some devices accepted only one of them. – Tallu 17/6, 2014 at 5:18

Locale IDs can be found in:

http://www.localeplanet.com/icu/

Steps to follow

Step 1 : Need to find which all Languages supported on Android

Sol - follow my above answer ie in cldr-1-8 Languages.

Step 2 : Since cldr-1-8 Languages does not give u Locale short form which is need to be found for desire language Sol - Once language is available in cldr-1-8 Languages list then check for the shortform in http://www.localeplanet.com/icu/ link

Example :For language Hindi [हिन्दी] (1)we need to search its present in cldr-1-8 language then (2)search for Hindi in http://www.localeplanet.com/icu/ for Locale id its comes out to be http://www.localeplanet.com/icu/hi/index.html this link and see Locale id from it .

Demetriusdemeyer answered 1/11, 2011 at 21:17 Comment(9)

How do you see the most recent list? And where is the locale short name (like "en" for English) in this list? – Tallu 29/3, 2014 at 18:48

Thanks, and so Android supports handling all of them, right? – Tallu 1/4, 2014 at 14:26

depends on cldr-1-8 listing of language, If it available in cldr-1-8 language listing then it definitely gone support. Need to cross verify is language is available in cldr-1-8 listing. :) – Outlet 2/4, 2014 at 5:12

I don't know what it means and how to check it out. – Tallu 2/4, 2014 at 5:20

Example if suppose u have to support Hindi language.Then search in above languages is HIndi is available if yes then search short form of Hindi in localeplanet.com/icu and for their u will get below link for Hindi language along with Locale Id ie short form localeplanet.com/icu/hi-IN/index.html – Outlet 2/4, 2014 at 6:36

so when you get to this website, how do you know if it has "cldr-1-8" language listing? and what does it mean " it definitely gone support" ? did you mean that it "has support" for it? – Tallu 2/4, 2014 at 6:39

What do you mean? I don't understand. – Tallu 2/4, 2014 at 17:31

I still don't get about step 1: what is "cldr-1-8" and in which website to look for it. Only thing I found is this: cldr.unicode.org/index/downloads/cldr-1-8-1 , and it doesn't show a list of languages (or locales). – Tallu 5/4, 2014 at 18:56

unicode.org/cldr/charts/latest/supplemental/… – Outlet 5/4, 2014 at 19:46

I think the best way is to run a sample code to find the supported locales. I've made a code snippet that does it:

final Locale[] availableLocales=Locale.getAvailableLocales();
for(final Locale locale : availableLocales)
  Log.d("Applog",":"+locale.getDisplayName()+":"+locale.getLanguage()+":"
    +locale.getCountry()+":values-"+locale.toString().replace("_","-r"));

the columns are : displayName (how it looks to the user), the locale, the variant, and the folder that the developer is supposed to put the strings into.

Here's a table I've made out of the 5.0.1 emulator: https://docs.google.com/spreadsheets/d/1Hx1CTPT82qFSbzuWiU1nyGROCNM6HKssKCPhxinvdww/

Weird thing is that for some cases, I got "#" which is something I've never seen before. It's probably quite new, and the rule I've chosen is probably incorrect for those cases (though it still compiles fine when I put such folders and files), but for the rest it should be fine.

If anyone knows about what the "#" is, and how to handle it, please let me know.

Tallu answered 1/11, 2011 at 21:17 Comment(0)

If you're using Android Studio you can:

Right click a directory on your project > New > Android Resource File
In the Available qualifiers section select Locale and click >>

You will see a list of all Languages and if you choose them you will see Specific Regions for each. You can also type in the list to filter languages.

Norvan answered 1/11, 2011 at 21:17 Comment(0)

First we need to plan how the application will render differently in different locals. Here it shows example, where the text string and images have to go.

de-rDE German / Germany res/values-de/ res/drawable-de-rDE/ 
fr-rFR French / France res/values-fr/ res/drawable-fr-rFR/ 
fr-rCA French / Canada res/values-fr/ res/drawable-fr-rCA/ 
en-rCA English / Canada (res/values/) res/drawable-en-rCA/ 
ja-rJP Japanese / Japan res/values-ja/ res/drawable-ja-rJP/ 
en-rUS English / United States (res/values/) res/drawable-en-rUS/

For more info you can see the page Localization

Countercheck answered 1/11, 2011 at 21:17 Comment(0)

As of Android 7.0, you can read the list from the Language settings straight in the source. You can see the Android version in the URL:

The list for Google Play descriptions is different:

Tambac answered 1/11, 2011 at 21:17 Comment(0)

I found a list, which might be the full list of supported locales by a given Android version (API level): go to Android-sdk\platforms\android-[XX]\data\res\values\ where XX means the API level, and open locale_config.xml with any text editor. It's human readable and can be easily processed if needed.

Where did you get it from? is it all of the languages? – Tallu 29/3, 2014 at 18:49

Just FYI, if you are unable to set any locale, the problem might be below attribute in your app level gradle file:

resConfigs "en", "hi" //to specify allowed locales for your app

So, if you want to support any locale other than English and Hindi, specify your locale here or just remove above line. By default your app will support all the locales.
