Android Serbian latin and Montenegro values folder for strings.xml

Question

I am trying to translate strings.xml for Serbian latin (srpski) and Montenegro (both Cyrillic and Latin) . I have included Serbian Cyrillic (српски) in values folder as values-sr. And it works fine. But for Serbian latin & Montenegro, I am unable to decide what should be the name of the values folder.I went through many posts in SO like

How to change locale to use Latin Serbian (instead of Cyrillic Serbian)

What should be the values folder name for Serbian (Latin,Serbia) (sr-rs-latn) language?

but they didnt help much.

I understand from https://github.com/championswimmer/android-locales that values folder should be :

Serbian (Cyrillic) sr --> values-sr-r_#Cyrl

Serbian (Cyrillic,Montenegro) sr ME --> values-sr-rME_#Cyrl

Serbian (Cyrillic,Serbia) sr RS --> values-sr-rRS_#Cyrl

Serbian (Latin) sr --> values-sr-r_#Latn

Serbian (Latin,Montenegro) sr ME --> values-sr-rME_#Latn

Serbian (Latin,Serbia) sr RS --> values-sr-rRS_#Latn

But if I try to create a folder like values-sr-rRS_#Latn in Android studio, it throws error "Invalid directory". Then I started some analysis.

1. In Nexus 9 Marshmallow, list of available locales using Locale.getAvailableLocales() lists all the serbian languages. So they are supported.

   sr
   sr__#Cyrl
   sr_BA_#Cyrl
   sr_ME_#Cyrl
   sr_RS_#Cyrl
   sr_XK_#Cyrl
   sr__#Latn
   sr_BA_#Latn
   sr_ME_#Latn sr_RS_#Latn
   sr_XK_#Latn

2. In Settings screen of Nexus 9, I can see option to only change to Serbian Cyrillic(српски) whereas in a Lenovo Yoga tab, I see option to change to only Serbian latin(srpski). When I debugged in both the devices, I found that both have sr as the language code and RS as the region code and the script code was blank. So how to include both values folder in app and how its mapped?

3. Should I create values folder like values-sr-ZZ or something for the languages I need and in code check for the script code?

4. But if that's the case, in resources folder of Google Play Games and Settings app I found that they have only one values-sr folder. So how do they handle values-sr-r_#Latn and values-sr-rME_#Latn and values-sr-rME_#Cyrl.

Can anyone please guide me ?

I have just successfully used:

values-b+sr+Latn
