Localization Of Android Application. One String Resources For Several Countries

I have such a question: I have an Login/Registration Activity which is by default is using Russian version of strings.xml. So when user is entering application - he sees text in Ru

Solution 1:

I would strongly recommend using lokalise

We have an app with 6 flavours and more than 16 languages. It would be a nightmare, if only this library didn't exist.

They have a tutorial on how to use custom locale: but in short:

// Create a new Locale objectLocalelocale=newLocale("ru");
    Locale.setDefault(locale);
    // Create a new configuration objectConfigurationconfig=newConfiguration();
    // Set the locale of the new configuration
    config.locale = locale;
    // Update the configuration of the Accplication context
    getResources().updateConfiguration(
        config, 
        getResources().getDisplayMetrics()
    );

Solution 2:

What you want to do is:

1. Have a list of language/locale wise content translations in the format of key-value pairs. You can achieve this within the same file or have separate files and name them according to the language-locale combo. I prefer the latter version, easier to maintain.

2. Next at time of app init, you want to read the phone's current locale with

   Localecurrent= getResources().getConfiguration().locale;
   

   Map this value to the content files (varies from framework to framework) created above and you have instant localization.
