Android Build an Interactive Story App Intents and Multiple Activities Investigating a NullPointerException

Could someone explain to me what he did

When he does the new stuff he doesn't explain anything. It's really hard to understand. It's only in this part of the course I haven't understood yet.

Hey Yusuf! I'm not sure I know which part you're referring to. What part do you find confusing?
