R.java file is empty, I don't know wheather the above error is the reason or not. My R.java is located in src/main/gen/com/example/results

Answer 1

Try the following:

-Migrate project to androidx

-Raise the minSDK and targetSDK

-update all dependencies to the newest version

This issue usually comes from an issue with a dependency in your build gradle. Either one is not compatible or up to date with the rest of the dependencies or the version you are using is bugged.
