Jetpack Compose — two years in production

Compose hit stable 1.0 in 2021. By 2026 it's the default for new Android apps. What worked, what hurt.

Jetpack Compose — two years in production

Jetpack Compose is the modern Android UI framework. Declarative, Kotlin-first, similar mental model to SwiftUI.

Jetpack Compose — two years in production
Adoption of Jetpack Compose for new Android projects in 2026.

What worked:

  • 30-50% less code than View XML + custom views
  • Animation API is excellent (better than UIKit, similar to SwiftUI)
  • Material 3 components mature enough for production
  • Multiplatform via Compose Multiplatform (KMP)

What hurt:

  • Performance on low-end Android devices — heavy recomposition kills scroll
  • Debugging is harder — recomposition trees are mental gymnastics
  • Mixing Compose and Views in legacy projects causes subtle bugs

For new projects in 2026: Compose. For legacy: gradual migration screen by screen, not all-or-nothing.
