debugging-recompositions

What problem does it solve?

This skill helps developers identify which Jetpack Compose composables recompose and why, using Android Studio Layout Inspector recomposition counts, per-parameter Argument Change Reasons, and runtime @TraceRecomposition to enable release-mode validation and end-to-end verification of fixes.

Core Features & Use Cases

• Identify recomposition sources with Layout Inspector counts and skip counts to prioritize optimization work.
• Inspect per-parameter Argument Change Reasons (Changed / Unchanged / Uncertain / Static / Unknown) to name the exact cause and guide the fix.
• Use runtime @TraceRecomposition in release builds to confirm that a fix eliminates recompositions on the hot path.
• Map diagnostic findings to targeted stability or skipping improvements and validate end-to-end behavior.

Quick Start

Enable recomposition counts in Layout Inspector, reproduce the scenario, then review the suspect composable argument-change reasons to plan the next action.
