I'm working through the Android Studio tutorials, specifically Android Fundamentals, 1.4 Learning to help yourself, and just learned the following method for adding activities: right-click the Java folder and select from New > Activity > Gallery.
Is there a way to cleanly Undo this action? Or does each class and layout (and other items?) entered have to be individually deleted?
[To all prospective tutorial writers. For every significant action explained, please include how to verify and how to undo. It's really helpful!]
