• You must submit two separate copies (one Word file and one PDF file) using the Assignment Template on
Blackboard via the allocated folder. These files must not be in compressed format.

• It is your responsibility to check and make sure that you have uploaded both the correct files.
• Zero mark will be given if you try to bypass the SafeAssign (e.g., misspell words, remove spaces between
words, hide characters, use different character sets, convert text into image or languages other than English
or any kind of manipulation).

• Email submission will not be accepted.
• You are advised to make your work clear and well-presented. This includes filling your information on the cover
page.

Project Instructions
•

The work on this project must be performed by a group (minimum of 3 and a maximum of 4
students).

•

Each group leader must send an email with the team member’s details.

•

Note each group needs to be approved by your instructor.

•

The work should be your own; copying from students or other resources will result in ZERO
marks.

•

This project is worth 14 marks and will be distributed as the following:
1. Part 1 – Implementation Part (9.5 points).
2. Part 2 – Presentation part (4.5 points).

Overview:
This project focuses on developing a mobile application using the Android platform. Each
student will select a topic of their choice (such as education, health, e-commerce,
entertainment, productivity, or social media) and design an app that provides a practical
solution to a real-world need. The project will highlight the student’s ability to plan, design,
implement, and test a mobile application while applying key Android development skills. It
should also include basic data persistence and a user-friendly interface.

MyStudyHelper
I. Project Description:
MyStudyHelper is a lightweight and intuitive Android application designed to assist students in organizing their study
materials, managing reminders, and accessing educational resources conveniently from a single platform. The application
focuses on improving study productivity and maintaining a structured learning approach for students of various
educational levels.
The app comprises the following core features:
1. Study Notes Management
o

Users can browse curated study notes on topics like programming languages (Java), Android
development, and data structures.

Each note contains a title, a short description, and detailed content.

Users can click on a note to view its full content in a dedicated detail screen (NoteDetailActivity).

Notes are presented in a clean, scrollable, and user-friendly RecyclerView with card-based layouts for
easy navigation.

2. Reminders
o

Users can add custom study reminders using an input field.

Reminders are displayed in a ListView and stored persistently using SharedPreferences, ensuring that
reminders remain available even after closing the app.

Users can delete reminders individually or remove the last added reminder.

This functionality helps students keep track of deadlines, study schedules, and important tasks.

3. Resources
o

The ResourcesActivity provides a placeholder interface for adding links to external study materials,
online courses, textbooks, or useful websites.

This feature is designed to centralize educational resources, making it easier for students to access
relevant study content.

4. About Section
o

The AboutActivity displays information about the app, including its name, version, developer details,
and contact email.

A simple back button enables users to return to the main dashboard easily.

5. User-Friendly Design
o

The app follows Material Design guidelines for consistent UI/UX across activities.

Themes, color palettes, and typography are chosen to provide a visually appealing and accessible
experience.

The splash screen and adaptive icons enhance the professional look and feel of the app.

6. Technical Implementation
o

Built using Java and Android SDK with a minimum SDK of 24.

Utilizes RecyclerView for dynamic note listings, SharedPreferences for persistent storage, and standard
Android UI components for efficient navigation.

The app architecture is modular, separating concerns between Activities, Adapters, and model classes
(Note).

View binding and structured XML layouts ensure maintainable and readable code.

7. Future Enhancements
o

Integration of cloud backup for notes and reminders.

Addition of user authentication for personalized experiences.

Expansion of study resources with external APIs for online courses and ebooks.

Interactive notifications for reminders and study schedules.

Conclusion:
MyStudyHelper is designed as a comprehensive study companion that merges simplicity with functionality. Its modular
design, persistent storage, and clean user interface make it suitable for students who want to organize their study
materials, manage reminders, and access resources efficiently. The app serves as a foundation for a scalable educational
tool with potential future integrations.
