Improve your Android App Performance by 10X with Compose Stability

Your Jetpack Compose app might be recomposing 10X more than it needs to. The culprit? Stability.

Compose's smart recomposition system only works when it can detect stable parameters. When classes are marked unstable, even unchanged data triggers unnecessary recompositions that tank your performance.

Key Takeaways

• Unstable classes force Compose to recompose even when data hasn't changed
• Use Compose Compiler reports to identify stability issues in your code
• Mark data classes with @Immutable or @Stable to enable skipping
• Collections and lambdas often break stability without you realizing it

The article reveals a surprising Kotlin feature that silently breaks stability in most codebases.
