Let’s just display a quick informative popup, which will only display an alert on screen with a title and a message in it. It actually gets closed when the back button get touched.
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.SetMessage("This is just an alert to show on the screen in order to try my alert demo.");
We will add OK and Canel button. On click of the buttons, it will display a quick Toast message on screen in order
to differentiate which button is clicked.
