Android get device locale

Question

Upon installation of my Android program I check for device locale:

String deviceLocale=Locale.getDefault().getLanguage();

If deviceLocale i

Answer 1

As you are changing the Application language programatically like

Locale locale = new Locale("en");
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
pContext.getResources().updateConfiguration(config, null);

And

But after that, in other methods, when I check device's locale like this:

String deviceLocale=Locale.getDefault().getLanguage();
I get result as "English". But device's locale is Spanish.

So instead of that use this below code to get the device's Local

try {
    Process exec = Runtime.getRuntime().exec(new String[]{"getprop", "persist.sys.language"});
    String locale = new BufferedReader(new InputStreamReader(exec.getInputStream())).readLine();
    exec.destroy();
    Log.e("", "Device locale: "+locale);
} catch (IOException e) {
    e.printStackTrace();
}

OUTPUT: Spanish Check this

Hope this exactly you are looking for.

The best way to design the app is to use a default lang, English in your case, under values/ and you can add addition langs under values-XX/. In this way when a language is not supported Android fallback to your default, so English. Let the OS does the work for you :) However, yes if you change the locale you'll get your last settings, so you have to save that information somewhere.

Although, the answer by @user2944616 is politically correct, that does not give an answer to the actual question posed.

So, if I really had to know the user set system locale, I'd use reflection (do not know any better option ATM):

private String getSystemPropertyValue(String name) {
    try {
        Class<?> systemProperties = Class.forName("android.os.SystemProperties");
        try {
            Method get = systemProperties.getMethod("get", String.class, String.class);
            if (get == null) {
                return "Failure!?";
            }
            try {
                return (String)get.invoke(systemProperties, name, "");
            } catch (IllegalAccessException e) {
                return "IllegalAccessException";
            } catch (IllegalArgumentException e) {
                return "IllegalArgumentException";
            } catch (InvocationTargetException e) {
                return "InvocationTargetException";
            }
        } catch (NoSuchMethodException e) {
            return "SystemProperties.get(String key, String def) method is not found";
        }
    } catch (ClassNotFoundException e) {
        return "SystemProperties class is not found";
    }
}

With that given and device locale set to Spanish (United States) / Español (Estados Unidos) following string

<string name="system_locale">System locale: <xliff:g id="profile_name">%1$s</xliff:g>&#95;<xliff:g id="device_name">%2$s</xliff:g></string>

and this code

private static final String SYS_COUNTRY = "persist.sys.country";
private static final String SYS_LANG = "persist.sys.language";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    TextView tv = (TextView)findViewById(R.id.locale);
    tv.setText(getString(R.string.system_locale, getSystemPropertyValue(SYS_LANG),
            getSystemPropertyValue(SYS_COUNTRY)));
}

yields following screen:

If desired, one could also easily construct Locale instance using the above:

Locale locale = new Locale(getSystemPropertyValue(SYS_LANG),
        getSystemPropertyValue(SYS_COUNTRY));
Log.d(TAG, "Language: " + locale.getLanguage());
Log.d(TAG, "Country: " + locale.getCountry());

Log output:

D/GetSystemLocale(5697): Language: es
D/GetSystemLocale(5697): Country: US

Hope this helps.

Answer 4

To get the device locale use this

Locale current = context.getResources().getConfiguration().locale;

and current.toString() will return you "en" "ar" etc

Answer 5

you should use String deviceLocale= Locale.getDefault().getDisplayLanguage(); to display the language instead of

String deviceLocale=Locale.getDefault().getLanguage();

Answer 6

You can access global locale by -

defaultLocale = Resources.getSystem().getConfiguration().locale;

Take a look at http://developer.android.com/reference/android/content/res/Resources.html#getSystem() -

Returns a global shared Resources object that provides access to only system resources (no application resources)

Update: As pointed out in comments 'locale' field is deprecated and you need to use getLocales() instead.

defaultLocale = Resources.getSystem().getConfiguration().getLocales().get(0);
