Top-Master's answer only work if you can downgrade to a specific version. In my case, I have a React Native app and one of the libraries I was using had migrated to AndroidX. The previous version had issues with iOS, so I had to use the most recent version. What I had to do was:

1. Migrate the Android project to AndroidX (Refactor > Migrate to AndroidX).
2. Use jetify to convert node_module dependencies to AndroidX. For React Native 0.60 and above, jetify is run automatically, so you don't have to install this library.
