Recomposition is when Jetpack Compose re-executes the composables that may have changed in response to state changes, and then updates the Composition to reflect any changes. A Composition can only be produced by an initial composition and updated by recomposition.

Conclusion: The debate between Jetpack Compose and XML layout for Android application development reflects the evolution and innovation in the Android ecosystem. While XML layout remains a reliable and widely-used approach, Jetpack Compose offers a modern, flexible, and powerful alternative.

It adopts a declarative approach, enabling developers to build UI components using Kotlin code instead of XML. Compose leverages the power of Kotlin's language features and functional programming, making UI development faster, more intuitive, and less error-prone.

Compose allows you to do more with less code compared to XML. Compose is Intuitive. This means that you just need to tell Compose what you want to show the user. Compose is compatible with all your existing code: you can call Compose code from Views and Views from Compose.

Jetpack Compose is demonstrated to have faster app startup time and rendering time for navigation and animation, whereas XML delivers smoother and faster rendering time when scrolling through a layout. Notably, Jetpack Compose has also shown an improvement in UI performance since previous works were conducted.

Althought Jetpack Compose greatly simplifies some aspects, I feel like designing there UI is actually slower than using xml layout, cause that UI code is way less readable and editable than xml. I found myself creating UI dynamically in situation where it wasn't really necessary, just to reduce amount of compose code.

For compose-based layout, the slow frame rate came out to be 8.91% whereas it was 9.93% for XML-based layout. Like frozen frames, ~10 out of 100 frames would fall under the slow frame category for XML-based layout. Whereas it was ~9 out of 100 frames for compose-based activity.

Jetpack Compose is a modern declarative UI Toolkit for Android. Compose makes it easier to write and maintain your app UI by providing a declarative API that allows you to render your app UI without imperatively mutating frontend views.
