Trippey App not working

Good Morning,

I’m working on :
Saving Data on Android, Episode 2: Set Up The Project | Kodeco

I’m trying to run the app but I’m having some issues. I’m getting this
error message when I run it.(See screenshot 1)

And when I implement the overridden functions, I get this error
message(See screenshot 2)
