I'm trying to run on:

Mac OS: 10.13.6
Node Version: 12.16.1
npm: 6.13.4
watchman: 4.9.0
Android Studio: 3.6.2

com.facebook.react.PackageList is not recognized or could not resolved when I try to build Android app and giving me error as follow:

11:48 AM	Executing tasks: [:app:assembleDebug] in project /Users/YeYint/Documents/hamagen-react-native/android

I was trying to fix it and tried many ways but no luck. Please kindly advise how to solve the problem.

see:
facebook/react-native#25787
also you can try to remove node_modules directory, then run yarn install before building the app

Thanks a lot. At first, I tried installing node_modules using npm install command and I try with yarn install according to your answer and solved the problem.

Thanks heap.
