The Video Calling App is an Android application that combines User profiles and Authentication, built with Firebase. The project follows a clean app architecture where UI, logic, and data stay separated, making it easy to test, extend, and present. It showcases practical Android techniques while producing a working, demo-ready app.
Users struggle to do this task conveniently from their phone because existing solutions are complex, slow, or missing. Without an Android app built on Authentication and Firebase, there is no simple, mobile-friendly way to manage the workflow with clear results.
This project applies Android development techniques through User profiles, orchestrated with Firebase and Authentication. The app is designed for usability and performance, with smooth navigation, validation, and error handling. It produces consistent, reusable results and can be adapted to related tasks with minimal changes.
