If you're building Android apps with Jetpack Compose, you know that performance often comes down to one key concept: stability. When your composables receive unstable parameters, Compose can't be sure if they've changed, forcing unnecessary UI redraws (recompositions) and slowing down your app.
A game-changing new tool, the Real-Time Stability Insights for Jetpack Compose plugin, is here to help you conquer this problem!
What Can This Plugin Do?
This essential Android Studio plugin gives you real-time visibility into your code's stability, making it easier than ever to write efficient Compose UI.
🚦 Code Inspection Markers: Say goodbye to guesswork! The plugin places visual markers right in your code:
Green: Parameters are stable and safe to skip during recomposition.
Yellow: Stability is determined at runtime (non-skippable), potentially missing out on compile-time optimizations.
Red: Parameters are unstable, guaranteeing frequent, unnecessary recompositions.
🔍 Stability Explorer Panel: Get a project-wide overview in a dedicated panel. You can quickly see which modules and composables have stability issues that require your attention.
🩺 Runtime Tracing: Use the powerful @TraceRecomposition annotation to track the exact number of recompositions for specific composables, inspect parameter changes, and debug performance bottlenecks right in your logs.
🛡️ Stability Validation: Prevent future problems! This feature can stop you from committing code to version control if it introduces new unstable types, enforcing performance from the start.
Why is Stability So Important?
A type (like a data class) is stable if its fields are immutable (val) and it has a proper equals implementation. Unstable types, especially those with mutable `var1 properties, force Compose to re-run your composable function every single time its parent recomposes, even if the data hasn't actually changed. By using this plugin, you can easily identify and fix these unstable types, leading to a much smoother and more performant user experience.
