I'm trying to organize the files in my project, I searched for a way of organizing the files and I found this https://stackoverflow.com/a/35102010/6866139, I created a project with no activities and added the packages and tried to create an activity inside the package name 'activities' then I got the error 'Cannot resolve symbol 'R' Here is the Project structure and error
I did clean and rebuild but it does not work. Is there any proper way to do this? Please let me know.
