When you click on the icon, the application crashes

When you click on the icon, the application crashes.
If I enter when I first launch the app from home activity to the trash. All OK. Then I add the item to the cart. Also everything is ok. But then returning to home and trying to enter the basket, I get an application crash and the following error

Your problem is at this line:
total+=(Integer.parseInt(order.getPrice()))*(Integer.parseInt(order.getQuantity()));

One of order.getQuantity() or order.getPrice() are not returning the expected result. You get "Tucano Espresso Decaf" returned instead of quantity or price.
Review these two methods or post them here so we can take a look.

Looks like a problem with AlertDialog implementation.
Try this once,
