As we know already e.g. we cannot change res
folder values and files at runtime,
I am working on an app, in which we are supporting more than 25 languag
Unfortunatelly resources couldn't be changed after compilation. The only way for you is to download language shema from server (i.e when app starts) and save it (or update if needed) in sqlite, file or in shared preferences (the storage options: https://developer.android.com/guide/topics/data/data-storage.html#filesInternal).
