This is my first Android app and I'm applying what I've learned so far into this project.
Its a simple calculator for people shopping at a grocery store. Users can add goods to the grocery cart and punch in
the price on the app to keep track of their grocery budget and not go over it.
The app basically stores the output as a String
. And when it comes time to do any calculation, the Strings are changed
into Doubles and then changed back into Strings to be displayed.
I think the String converting to numbers and back again are part of the problem along with that If statement.
The app loads the splash screen and the switches to another Activity that is the Calculator. The calculator loads just fine,
but if any button is pressed, the App will crash. I tried to figure it out for hours, but here I am now. Please help. Any
input would be greatly appreciated.!
