I think for non-instantiatable we typically use the private constructor pattern
instead of the abstract pattern.

+     * language codes into the modern ones used by Chromium.

+    public static String getDefaultLocale() {
+        Locale locale = Locale.getDefault();
+        String language = locale.getLanguage();
+        String country = locale.getCountry();
+
+        // Android uses deprecated lanuages codes for Hebrew and Indonesian but Chromium uses the
+        // updated codes. Also, Android uses "tl" while Chromium uses "fil" for Tagalog/Filipino.
+        // So apply a mapping.
+        // See http://developer.android.com/reference/java/util/Locale.html
