Google’s transition of Android UI development from the XML layout system to Jetpack Compose has been, by the standards of platform UI framework migrations, unusually smooth. Compose became stable in August 2021. By 2024, it was the recommended approach for new Android development. In 2026, the question for Android teams is no longer whether to adopt Compose but how to manage the migration of existing View-based codebases.

The comparison with SwiftUI is instructive. Both frameworks launched within two years of each other, both represent declarative replacements for older imperative UI systems, and both have faced criticism for gaps between their initial capabilities and the full feature set of what they replaced. Compose has navigated this transition with fewer of the minimum-API-level constraints that limit SwiftUI’s adoption curve, because Android’s broader device compatibility requirements have historically pushed Google toward more conservative backward compatibility policies.

Google’s decision to build Flutter on top of Dart — a language that had minimal developer mindshare and an uncertain future when Flutter launched — was a risk that the broader developer community viewed with skepticism. Dart was not JavaScript. It was not Kotlin. It was not a language that developers had strong feelings about because most developers had never used it. Building a cross-platform UI framework on an obscure language was, on its face, an unusual strategic choice.
