Need help with the mobile app- I'm a 14yr old coder

this img was from a youtube video which I was following.
I’ve downloaded it from the offical link that was on Google play store and my phone is a Galaxy with Android OS.

If there’s anyone who can help me or tell me what’s going on I’d be really glad.
Thank you
