what is android-expert fr?

This repository holds the source code for a free beginner Android development course taught in Spanish. The course teaches how to build Android apps using the Kotlin programming language, starting from scratch with no programming experience assumed. The curriculum covers Kotlin basics first: variables, functions, conditional statements, arrays, and lists. From there it moves into building actual Android apps. The course builds four complete example apps from start to finish: a BMI (body mass index) calculator, a task organizer, a superhero search app that fetches data from an external web API, and a settings screen that saves preferences and supports a night mode. Screenshots of each app are included in the README. The course runs live on Twitch, where the instructor explains the material and answers questions in real time. Edited recordings are later uploaded to YouTube. At the end of each session, exercises are assigned and reviewed at the start of the next one. Students can ask questions in a dedicated Discord channel. This repository is a learning resource, not a finished app for end users. All the material is free. The repository exists so students can follow along with the code, compare their work, or catch up on earlier lessons.
