This constant context switching definitely has some impact or productivity, which we've come to accept. When you need to reference styles and dimensions, you store them in XML. You add business logic to your screens using Kotlin/Java and then reference the XML views using IDs/tags. The current workflow involves defining views in XML files. The average Android developer workflow involves a lot of context switching.This has also made it harder to introduce new patterns and changes. The infamous View.java file, which is one of the most critical parts of the Android views system, is now 30k lines long. However, the view system in Android has largely remained unchanged. There's been great progress with the introduction of Jetpack that started to break down core components into more maintainable libraries. The development experience and expectations in 2021 are significantly different than what they were when Android first launched in 2008. Some critical Android APIs were created over a decade ago.Unbundling the view system from the OS makes it easier to quickly fix bugs and bring improvements in a backward-compatible way. This means that if the Android team made some new improvements in the View system, we'd have to wait for an Android API release to get these improvements. The existing Android UI toolkit is tied to the operating system.

This is a huge undertaking, even for a company at the scale of Google, so it's important to understand why a framework such as Jetpack Compose is even needed. Jetpack Compose is a complete rewrite of the Android UI toolkit from the ground up.

The move to using declarative programming for describing UI is a welcome change and one that is prevalent across platforms with the introduction of frameworks like React for Web, SwiftUI for iOS, and Flutter for cross-platform development. It simplifies and accelerates UI development on Android and is a paradigm shift in Android development as we know it. This changes with Jetpack Compose, Android's modern toolkit for building native UI. What didn't change in all these years is the Android UI toolkit.

Over the last few years, Android development has made significant changes in how apps are structured, the language used for development, the tooling and libraries that speed up development, and the improvements in testing apps.
