debugging-recompositions

Debug Jetpack Compose recompositions by enabling Layout Inspector counts in debug builds to identify suspect composables, then inspect per-parameter Argument Change Reasons to pinpoint the exact cause. This maps each status like Changed or Uncertain to a targeted fix.

Argument Change Reasons in Layout Inspector indicate why a composable recomposes. Changed means the parameter value modified, Unchanged means it stayed stable, Uncertain means stability is unverified, Static means it never changes, and Unknown means the cause is unmapped.

Yes, you can trace Jetpack Compose recompositions in release builds by using the runtime @TraceRecomposition annotation. This confirms that your stability fixes eliminate recompositions on the hot path during end-to-end behavior validation on real devices.

The best way to verify Jetpack Compose stability fixes is to first diagnose recompositions using Layout Inspector counts and Argument Change Reasons in debug builds, then validate the end-to-end behavior on real devices using runtime @TraceRecomposition in release builds.

Jetpack Compose composables recompose when the state value has not changed if a parameter is marked as Uncertain or Unknown in the Layout Inspector, indicating the compiler cannot guarantee stability, which requires applying targeted stability improvements.

You need Android Studio Hedgehog or a compatible version to inspect Jetpack Compose recomposition counts. The Layout Inspector counts and per-parameter Argument Change Reasons features are integrated into the IDE to diagnose and map recomposition causes accurately.
