Compose Motion (Jetpack Compose Animation)

A Jetpack Compose animation playbook: which API to pick, opinionated spring specs, and the performance anti-patterns to avoid.

Dev & CodingIntermediate★ 286⑂ 25AI score 9/10Last updated: Jul 31, 2026

What it does

  • Gives a decision tree for choosing between animate*AsState, AnimatedVisibility, Crossfade, AnimatedContent, updateTransition, Animatable, and SharedTransitionLayout.
  • Supplies opinionated spring defaults (stiffness / dampingRatio) for UI snaps, tactile feedback, bouncy reveals and 1:1 drag tracking.
  • Corrects performance anti-patterns with BAD/GOOD snippets: animating layout width, LaunchedEffect(true), missing key in LazyColumn, nesting AnimatedContent per list row.
  • Includes a gesture modifier map (draggable, anchoredDraggable, transformable) and reduced-motion accessibility handling.

Who it's for

  • Android engineers building UI with Jetpack Compose or Compose Multiplatform.
  • Anyone chasing jank or dropped frames in animated lists.
  • Developers adding hero / shared-element transitions between screens.

Example uses

  1. "Slide-animate my tab switcher" → get an AnimatedContent + togetherWith transitionSpec.
  2. "Animate the thumbnail from list to detail screen" → get the SharedTransitionLayout + rememberSharedContentState(key) scope-plumbing pattern.
  3. "My expanding card animation drops frames" → get refactored from animated width to graphicsLayer scale.
