This document describes an Android-based attendance system app that was developed for tracking student attendance in schools and colleges. Some key points: 1. The app allows teachers to record student attendance digitally rather than on paper, and automatically notifies parents via mobile phones if their child is absent. 2. It was created using Android SDK and Java programming languages, and stores attendance data in a MySQL database. 3. The app aims to reduce paperwork, save time, and improve communication between schools/colleges and parents regarding student attendance.
