## Overview

This Android food-donation app connects donors listing surplus food with receivers seeking nearby donations. Its documented workflow moves from sign-in to a dashboard, then into donation, browsing, mapping, history, profile, and settings features. The sampled MainActivity verifies the signed-in user, checks a Firebase donation-pin mapping, and launches several feature activities. Other feature implementations are not present in the supplied tree, so their paths point only to the existing app directory and their links rely on README documentation.

Main entry points: [`MAIN ACTIVITY.java`](https://github.com/uzaam07/food-donation-application/blob/main/MAIN%20ACTIVITY.java) (Dashboard), [`app`](https://github.com/uzaam07/food-donation-application/tree/main/app) (Food map)
