Write an Android app by employing the Model-View-Controller architecture.

The view contains four labels and a button. The first two labels represent two cards

in a simplified blackjack game and are _lled with two randomly generated integers

with values between 1 and 11 inclusive. The total of the two is displayed inside the

fourth label. When the user clicks on the button, if the current total shown inside

the fourth label is 15 or less, the third label is filled with a randomly generated

number between 1 and 11 inclusive and the total inside the fourth label is updated

to equal the sum of the three numbers in labels one, two, and three. If the current

total shown inside the fourth label is greater than 15, nothing happens. Include a

Model. Do not use XML.
