From Wikipedia, the free encyclopedia

Jetpack Compose is an open-source Kotlin-based declarative UI framework for Android developed by Google.[1] The first preview was announced in May 2019,[2] and the framework was made ready for production in July 2021.[1]

History[edit]

The first preview of Jetpack Compose was announced at the Google I/O conference in May 2019.[2] The developer preview was released in October 2019,[3] and the alpha release took place in August 2020.[4]

Compose entered its beta phase in February 2021, with its first production release taking place that July.[5]

Features[edit]

Jetpack Compose supports Android 5.0 and later.[6] It uses the Kotlin programming language, and provides a reactive programming model similar to other UI frameworks such as Vue.js and React Native.[2] Compose is designed to integrate seamlessly with existing Android apps and libraries, allowing developers to gradually convert their apps to Compose.[5]

In Compose, a user interface is defined using functions that have been annotated with the @Composable annotation, which are known as composable functions and define the screen's state.[1][7] The annotation is used by the Compose compiler to generate the UI boilerplate code.[7]

The 1.0 release introduced Compose Preview, which is built into Android Studio starting with Arctic Fox. It allows composables to be previewed using different configurations without deploying the app to a device.[8]

Usage[edit]

At the time of Jetpack Compose's 1.0 release, Google said, "There are already over 2,000 apps in the Play Store using Compose – in fact, the Play Store app itself uses Compose."[1] As of October 2022, 160 of the top 1000 apps on the Play Store included Compose. The apps included those from companies such as Airbnb, Lyft and Square.[9]

Google rewrote parts of Android's Settings app to use Compose in Android 14.[10]

Compose Multiplatform[edit]

Compose Multiplatform is a multi-platform UI framework developed by JetBrains and based on Jetpack Compose. It is a port of Jetpack Compose for Windows, macOS, Linux and the web. Version 1.0 alpha was released in August 2021.[1] iOS support was added in May 2023.[11]
