I have found it surprisingly difficult to find a comprehensive list of locales supported on Android. This is true for many reasons (locales are astonishingly complicated), but it seems like it should be easy to find the list of all locales that come back from java.util.Locale.getAvailableLocales(). Rather than add yet another answer to this Stack Overflow question, I thought I would share my own dump of locales here.

So here is what I got when I called Locale.getAvailableLocales() on my Pixel running Android 7.1.1, and then called toString() on each one:
