sabikrahat/Attendance-App — reverse-engineered prompt

Build me a simple Android attendance app in Java for a college or school setting. I want it to feel like a basic student project that actually works, not something overly fancy.

The main flow should be easy. Let me create a class or subject, add a list of students, open a class on a given day, and mark each student as present or absent. I should be able to save that attendance, come back later, and view past records by class and date. A small summary view would be nice too, like total presents, absences, and attendance percentage for each student.

Keep the design clean and straightforward, with a few simple screens and buttons that make sense on a phone. Make sure the data is stored locally so it still works without internet. If something is unclear, choose the simplest practical option and make the app feel complete enough to run and demo. You can look up current Android docs if you need to.
