kotlin Birthdaycard app

app development question and need an explanation and answer to help me learn.

Create a Birthday Card app that accepts a person’s name and date of birth. Clicking the Submit button will load a new activity which will display the person’s name, age, birthstone, and Chinese Zodiac sign.
Submit screenshots of the activities, layout files (.xml), code behind file(s) (.kt), and manifest file.

This should likely be done in android studio.
