Library Management Android App

This project is an Android App which aims to provide a solution to manage a Book Library. Designed for both Users/Students and Library Admins, various operations such as adding/removing/updating books, searching books, issuing/re-issuing/returning books, seeing issued books with due dates, collecting fines, etc. can be performed. The App uses Cloud Firestore as the back-end database for storing details of the Books and Users. Firebase Cloud Messaging is used to send realtime notifications to Users if a return deadline is approaching, his/her fine is increased, or when a new book is added to the Library. Cloud Functions are used to monitor the database in order to update fines and trigger notifications. The App has a user-friendly and interactive interface.

A detailed description of this project along with the screenshots can be found here.

Usage

This App is not live at the moment and won't work off the shelf.

  • Create a new Firebase Project (with Firestore Database) on Firebase Console and configure it with the App.
  • Setup a Node.js and Firebase CLI environment to deploy the Cloud Functions.
  • Setup a cron job to trigger the "updateFine" Function once every day through a HTTPS request.

I would recommend following YouTube Tutorials, Online Guides, and Official Documentation to get help in setting up the Project.
This is where I started: Cloud Firestore Android Tutorial

Tools Used

  • Android Studio : Primary IDE for Android App Development using Java.
  • Cloud Firestore : The Database used for storing data in the form of Collections and Documents.
  • Firebase Cloud Messaging : Used for sending Push Notifications to specified users using FCM Tokens.
  • Cloud Functions : Used for real-time monitoring on the database and listening to certain triggers for taking required actions.
  • Firebase Authentication : Used to maintain Accounts and perform Login and Signup Actions.
  • cron-job.org: Used for scheduling Cloud Functions through HTTPS Requests.

Future Work

  • UI Improvement and Optimization
  • New Features/Functionalities
  • Generalization for Flexible Usage. This App was implemented specifically for my College's Library System:
    • Books and Users are identified through unique Book IDs and Card No. respectively.
    • While issuing/re-issuing/returning a Book, 2 digits need to be added at end of its Book ID (to specify the unit number). For example, copies of a Book with ID 14532 having 25 units would have the IDs 1453201, 1453202, 1453203 ... 1453225. Book IDs are displayed in the same way in User Account's end.
    • Email ID for registration needs to be of the domain @iiitnr.edu.in.
    • Books are issued for a duration of 14 days, after which a fine of Rs.1 per day is incurred (if the book is not re-issued or returned).
    • A book can be re-issued only 1 time from the User's end.
