I am trying to run an app on an Android emulator. I followed the instructions in the React Native docs for installing Android Studio and setting the environment variables. I can create a default project with '''npx react-native init''' and run it without problems, so I guess my installation is fine. I cloned the repository, "npm installed" and got the following errors, trying to build fails as well. Since I am completely new to React Native and did not participate on this project so far I am clueless on how to approach this.

Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.Read more about autolinking: https://github.com/react-native-community/cli/blob/master/docs/autolinking.mdinfo Running jetifier to migrate libraries to AndroidX.
