EvenTrack Artifact

Code Review

This walkthrough highlights the Android logic, Firebase integration, and how permission handling and external testing methods were applied. It also demonstrates the use of SensorManager and activity lifecycle optimizations.

EvenTrack Code Review

Original Artifact

The original version of EvenTrack was a static prototype UI created for my CS-360 Mobile Architecture & Programming course. At that stage, the app included only basic layout concepts and placeholder screens, with limited login functionality and no real-time event tracking capabilities. It primarily served as a demonstration of layout design, screen navigation, and foundational mobile development practices using Android Studio.

While the prototype effectively introduced concepts like RelativeLayout, GridViews, and activity transitions, it lacked data persistence, user authentication, and interactive features—essential elements for a production-ready mobile application. The experience gave me a solid starting point and sparked the idea to transform EvenTrack into a fully functional event management tool with real-world usability and backend support.

Enhancement

EvenTrack originated as a project in my CS-360 Mobile Architecture & Programming course. While the original version met the academic requirements of the class, I saw the potential for something much greater. This enhancement phase was an exciting opportunity to reimagine the app with a modern look and feel while expanding its functionality into a more complete event management tool.

My goal was to dive deeper into the codebase and implement a polished, user-centered UI redesign that feels intuitive, responsive, and visually sophisticated. EvenTrack now empowers users to add, track, and manage their favorite events seamlessly.

The enhanced application includes secure Firebase Authentication, real-time Firestore integration, SMS permission handling, and a lifecycle-aware architecture. These updates not only elevate the performance and reliability of the app but also deliver a more meaningful and engaging user experience.

Checkpoint Summary

Technical Reflection

I used MongoDB Compass for local database management and intuitive data visualization, ensuring data integrity and query efficiency while adhering to the principles outlined in the OWASP Top Ten security standards. Concepts from CS-340: Client/Server Development and CS-465: Full Stack Development I informed my approach to designing secure, scalable APIs, emphasizing separation of concerns, modular architecture, and non-blocking asynchronous flows for improved performance and maintainability. Additionally, I strategically configured Firebase authentication and Firestore security rules to enforce role-based access controls, striking a careful balance between application functionality and robust user data protection.
