Happy coding.....

Answer 2

you need two things for that :-

1. different values folder in res.
2. Custom typeface font to support your regional language.

like as follows :-

MyProject/
    res/
       values/
           strings.xml
       values-es/
           strings.xml
       values-fr/
           strings.xml

Updated method to get available indian locales (2020)

Use android's inbuilt Locale package to get available locales. Then filter the indian languages and finally to display them in their corresponding font, use locale.getDisplayLanguage(locale) as shown below:

for(locale in Locale.getAvailableLocales())
 if ("IN" in locale.country)
  availableLanguages.add(Pair(locale.language,locale.getDisplayLanguage(locale)))
