Discuss how one can change a package name so it will be under his or her name.

HiI\’m beginner in Android Studio and I need a Simple coded app described below.I would also want to know how I can change a package name so it will be under my name. Build a Learning app that tests the user’s timing and response to challenges posed by the app.The app should time the user to respond to a challenge. The user should be awarded points based on meeting a specific challenge successfully. Make sure the app presents rules to the user on how to play.  Also make sure the app has a way to end the challenge e.g. if the user reaches a maximum number of points, or when the user uses up all of their chances.  The app must use Shared Preferences to store the user’s achievements such as high scores, skill level information etc. This information should be presented to the user when the app ends or anytime the user wishes to check e.g. at the start screen.  Also, make sure the app uses graphics to communicate progress or messages to the user. This app must be educational.
