Correct localization on Android 7

Prior to Android 7, the system had a single preferred locale, and fallback behavior was quite rudimentary. Starting with Android 7, the user can now specify a priority list of locales, and fallback behavior is improved.

However, in many cases it is still surprisingly difficult to make full use of locale fallback, and there are some hidden gotchas when trying to fully support both Android 7 and earlier versions.
