"One" and "1" are not same, such as "1st place" vs "a
place". Also in many languages, plurals expression is different with English, for more detail please check: go/android-i18n-plurals.
So in string res file, replace "one" with excat value "1" is a more
proper way.
Test: Existing unit tests still pass.
