By default this detector allows regions of a language to just provide a
subset of the strings and fall back to the standard language strings. You
can require all regions to provide a full translation by setting the
environment variable ANDROID_LINT_COMPLETE_REGIONS.
You can tell lint (and other tools) which language is the default language
in your res/values/ folder by specifying tools:locale="languageCode" for
the root <resources> element in your resource file. (The tools prefix
refers to the namespace declaration http://schemas.android.com/tools.)
