Why did you need to move this from LocalizationUtils?

Seems exactly the same as the other file.  And it didn't have any native
dependencies before, so this seems unnecessary indirection.

The reason I moved this is due to its usage in ResourceExtractor.java. 
Keeping the file LocalizationUtils 'as is' in  and calling it from base would
create package dependency on org.chromium.ui.base. Is it ok to have this cross
dependency?

Ah ha...I missed the ui part of the package.  That definitely is not allowed
(you can check base/DEPS).

This is fine to move then.  Personally, I think we should move more of
LocalizationUtils to this file to make it more the one stop for any Locale
related info on Android.  I don't necessarily think we should do it as part
of this CL, but if you can add a TODO in the other file to make all native
callers depend on this directly instead of the indirect hop it would be good.

Sure, I will put a TODO there and mostly will make the change in subsequent CL.

+        String country = locale.getCountry();

+        // updated codes. Also, Android uses "tl" while Chromium uses "fil" for Tagalog/Filipino.
+        // So apply a mapping.

+        } else if ("tl".equals(language)) {
+            language = "fil";
+        }
+        return country.isEmpty() ? language : language + "-" + country;
