Desent Solutions – Android Challenge
Mobile Code Quest
Fix broken Kotlin/Compose code, level by level. Each level has buggy or incomplete code — edit it in the editor, run the tests, and advance. No compilation needed — we validate your code structure.
Ready to Start?
Sie haben 6 Stufen von Kotlin/Jetpack Compose Herausforderungen. Jede Stufe enthält fehlerhaften oder unvollständigen Code, den Sie korrigieren müssen. Die Uhr beginnt, wenn Sie starten. Zielzeit: ca. 30 Minuten.
How It Works
Read the code
Each level has a Kotlin code snippet with bugs or missing pieces.
Fix it
Edit the code in the built-in editor. Use your Kotlin/Compose knowledge.
Run tests
Click 'Run Tests' to validate your fix. All tests must pass to unlock the next level.
