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?

You'll have 6 levels of Kotlin/Jetpack Compose challenges. Each level gives you broken or incomplete code to fix. The timer starts when you begin. Target time: ~30 minutes.

How It Works

1

Read the code

Each level has a Kotlin code snippet with bugs or missing pieces.

2

Fix it

Edit the code in the built-in editor. Use your Kotlin/Compose knowledge.

3

Run tests

Click 'Run Tests' to validate your fix. All tests must pass to unlock the next level.

4

Conquer all 6 levels

From Compose basics to ViewModel, coroutines, navigation, and a LazyColumn boss fight.
