Providing custom activity name instead of main activity in android studio while creating new project

Question

I have just started learning to use Android Studio and using examples of login and registration codes given in various blogs.

Problem: Whenever I launch a new project, the default empty activity that gets loaded is named as MainActivity. If I change the activity name later, it leads to various build errors. I am using AndroidStudio 3.3.2.

I tried creating a project with no activity and tried adding an empty activity after the project is created. The activity got created however, when I try to run the app, I get an error Default activity not found.

How do I create a project with custom name for activity?

Answer 1

actually it's very easy. you can refactor the file name and Android Studio handle the errors.
