Task Management Android Application Project 2024-2025

This application is an exercise for the Mobile Application Development course at Harokopio University of Athens – Dept. of Informatics and Telematics.

Overview

This Android application is designed to help users manage their tasks efficiently. It allows users to create, view, update, delete, and export tasks with a user-friendly interface. The app ensures that task statuses are updated automatically based on their start time and duration.

Features

• View Tasks: Display all incomplete tasks, with urgent tasks appearing at the top.

• Mark Tasks as Completed: Change the status of tasks to "completed" with a single button click.

• Location Integration: View task locations on Google Maps if a location is provided.

• Export Tasks: Export incomplete tasks as an HTML file to the Downloads directory, viewable in other applications.
