Android package tracking service

The Delivery & Tracking App is a mobile solution built with Java and Firebase, designed to connect customers and drivers in a logistics workflow. It supports secure user registration, login, and session management using Firebase Authentication.

The system uses Firebase’s real-time database and GeoFire to continuously track driver locations, storing coordinates in an efficient structure that enables responsive updates on both customer and driver maps.

Android’s Location Listener and Google Cloud API integration enable accurate geolocation, routing, and ETA calculations. Polylines dynamically render routes for drivers and customers, ensuring both sides see the same up-to-date delivery path.

Drivers are able to register deliveries, accept routes, and verify deliveries using one-time customer codes. Customers can view pending deliveries, track drivers in real time, and confirm delivery codes on completion.

The app applies image handling and storage with FirebaseStorage, including compression and bitmap transformations for efficient upload and retrieval of driver or package images.
