get the application's resources languages

Question

Is it possible, at runtime, to know which resources languages are embedded in my app?

i.e the presence of this folders:

values-en
values-de
values-fr         


        

Answer 1

Inspired by Mendhak's solution I created something a bit cleaner:

    defaultConfig {
        ....

        def locales = ["en", "it", "pl", "fr", "es", "de", "ru"]

        buildConfigField "String[]", "TRANSLATION_ARRAY", "new String[]{\""+locales.join("\",\"")+"\"}"
        resConfigs locales
    }

Then in Java use:

BuildConfig.TRANSLATION_ARRAY

Advatages of this method:

• Smaller apk - resConfigs will cut out resources from libraries which you don't need (some have hundreds)
• Fast - No need to parse resource configurations
