Write an android application

It is a high school day at OSU and your task is to write an app to tabulate how many prospective students attend. The activity should have buttons for each of the majors in the Applied Technology Department:

BS in CS, BS IT, CS, and Game Dev

There is a counter for each of the majors and every time a button is pressed, the appropriate counter should be incremented. A display button when pressed should display the number of each majors in the form a Toast. There is a clear button which pressed should set the number of each major to zero. The About button should use a Toast to show the name of the program, the date and your own name.
