Grammatical Inflection API provides a more personalized, natural-sounding user experience for users speaking languages where grammatical gender changes the sentence based on the addressee.
For example: French 🇫🇷
Chère cliente[Feminine], cher client[Masculine] — Dear client [EN]
Grammatical Inflection API introduce in Android14 which helps us to accommodate this.
Let’s see it in Action
- We need to add alternative resource files and append the grammatical gender after the locale name
These resources files should only contain strings that support grammatical gender inflections
- Put other strings in the default resource files

Initialize the GrammticalInflectionManager
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val grammaticalInflectionManager =
getSystemService(GRAMMATICAL_INFLECTION_SERVICE)
as GrammaticalInflectionManager

setRequestedApplicationGrammaticalGender(
Configuration.GRAMMATICAL_GENDER_FEMININE)
