"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. Bug: 199230342 Change-Id: I832abc38afc5d8816fa803865c25e6017cffa2c6
