Android Mobile Application Development in Kotlin I undertook the development of a mobile application for Android using Kotlin, making use of the Material UI component library and coroutines. The application, designed for mobile phones, aimed to display and modify information stored in RFID chip memory. To achieve this, the app connected via Bluetooth to an RFID reader. An SDK providing the RFID reader API was integrated into the APK. Coroutines were employed to manage the asynchronous calls to the SDK, which was developed in Java. Following user interviews, I compiled a backlog and proceeded to carry out developments using an agile methodology with one-week sprints. The technologies utilized include Android Kotlin, Coroutines, MVVM architecture, Material components, and version control with Git and GitLab.
