JAVA ERROR: React native basic project not working in android studio

Question

I'm followed all the steps from this document to install and run react native project in android studio.

https://reactnative.dev/docs/environment-setup

When I run the command npx react-native run-android to run the project in emulator, I got below error in terminal.
