I can't detect the bug

Question

This is a read/scan NFC code.

I'm trying it out and I need it to work so that I would write my own code for another read activity.

The app keeps on crashing and the error is always, "There's a bug, please fix it for the app to start."

The source video/code was this link https://www.youtube.com/watch?v=QzphwRdJ7r0
