@QatarCoin
Thank you so much for reporting this issue. This is fixed and will be published soon.
Added some more explanation to make it easier to understand.

Use the rollButton object and set a click listener on it by calling the setOnClickListener() method. Instead of the parentheses following the method name, you will actually be using curly braces following the method name. This is a special syntax for declaring a Lambda, which you'll learn more about in a future codelab.

What you need to know for now is that within the curly braces, you put instructions for what should happen when the button is tapped. You'll have your app display a Toast, which is a brief message in the next step.
