It describes hot reloading Jetpack Compose code changes on physical Android devices and emulators in one to three seconds while preserving app state as much as possible, and explains the engineering constraints and capabilities involved. ### Source excerpt Upsplash@lenaborge In Jetpack Compose development, you are probably rebuilding your app tens of times per day to adjust the subtle design specifications. Each rebuild takes anywhere from 1 min to several minutes (~30 mins depending on your project scale), followed by navigating back to the screen you were working on and reconstructing the state you just lost for fair self-testing. Let's be honest. That adds up to one to two hours of dead time per day, every day, spent waiting instead of iterating. Well, for some, it's the perfect coffee break. For others, it's a frustrating blocker that slows everything down. That's exactly the problem Compose HotSwan is built to solve. Compose HotSwan is a JetBrains IDE plugin for Android Studio/IntelliJ and a Gradle compiler plugin that performs Jetpack Compose hot reload on real physical Android devices/emulators, applying code changes to a running app in one to three seconds with full state preservation as possible. In this article, you will explore what you can do with Compose HotSwan, the engineering constraints that make hot reload on Android difficult, how Compose HotSwan works within those constraints, and its core capabilities. The build tax: What slow feedback actually costs you Every Android developer knows the routine. You tweak a modifier, hit run, and wait. The build compiles, dexes, installs, and restarts your app. It launches from the home screen. You tap through multiple screens, scroll to the right position, and recreate the state just to see a one-line change. This is not just an inconvenience. It changes how you make decisions, and the cost compounds throughout your day. Picture this. You are working on a screen buried several layers deep. Everything is set up exactly where you need it. You change fontSize = 16.sp to 18.sp. Gradle starts building. On a small project, it takes a minute. On a large codebase, it takes much longer. The app reinstalls and restarts from the "home screen". All your state is gone. Now y ## Using Compose Hot Reload to Build a Vaporwave-Inspired Compose Desktop Project DevFeed: [Using Compose Hot Reload to Build a Vaporwave-Inspired Compose Desktop Project]() Original publisher: [Read original article]() Published: 2025-06-09T10:52:55Z Content type: tutorial Language: en Sources: [maiatoday]() Topics: [compose-hot-reload](), [Compose](), [Kotlin](), [Gradle](), [multiplatform](), [repo]() Tags: [animate](), [code](), [compose](), [compose-hot-reload](), [gradle](), [kotlin](), [multiplatform](), [reload](), [repo](), [vaporwave]() ### AI overview An exploratory tutorial on using JetBrains Compose Hot Reload in a Compose Desktop project, with Vaporwave as the visual theme. It covers project setup, Kotlin 2.1.20 or later, plugin configuration, the foojay resolver, and running the application. ### Source excerpt Why I want to play with the recently released Compose Hot reload feature by JetBrains. To do this I setup a Desktop compose project and picked a topic to draw and explore: Vaporwave Why? because Vaporwave is a curious Internet thing. It has a strong visual aesthetic that I wanted to recreate. It is intriguing. It is seems to be a fleeting transient phenomena: it is in the name vapor and wave and yet... and yet we see it pop up in unexpected places. It is a form of hauntology: a cultural idea that returns from the past to haunt the present. There will be ramblings interspersed and remixed with code, I will put the code at the beginning of the sections, so that you can easily skim if remix-rambling is not your thing. Yes, there is a matching repo. Yes, it is a mix of organic hand coding and AI enhancements. I will explain my process. But first Setting up Hot Reload You need: A project that has a Compose desktop part. It can be stand alone or part of a multiplatform project Use a Kotlin version 2.1.20 or later Get the plugin and the latest version information and add it the place you keep your versions, like a toml file Setup the plugin in your build.gradle.kts Setup the foojay resolver Run the main application from the gutter icon or command line. something like ./gradlew runHot --mainClass MainKt --auto Optional extra make a run target for your particular main application if you have more than one See and example of each line in the sample repo Wow these instructions are vague! indeed things change quickly. Please follow the original repo. This post will date. Origins and Sound track Vaporwave appeared as a music genre with a strong aesthetic, some say in 2010. The iconic album Floral Shoppe by Macintosh Plus is still available and makes a perfect sound track for inspecting the code or reading this article. Go ahead click the link and start the music. I'll wait. We are on the cusp of widespread changes in how we interact with technology. Will we have nostalgia for the
