They include local settings for the IDE, project, and dependencies.ĪndroidApp/ folder: the root directory for the Android app project in our larger KMM project that has all of the Android side’s UI logic.īuild/ folder: contains output from your KMM builds. idea/ folders: local files that should not be committed to source control for most Android Studio projects. It uses Gradle with the Kotlin Multiplatform plugin applied and has targets for Android Kotlin Multiplatform Project Folder Structure This is a Kotlin Multiplatform module that compiles into an Android library and an iOS framework. Shared module contains the core application logic used in both target platforms: classes, functions, and so on. You can use it to store global configuration in its adle(.kts) or gradle.properties.

The root project does not hold source code. In this section, you will have to give your project a name, select your minimum SDK, Save location, Package name, and iOS, Android module name. Update Android Studio to the latest or at least version greater than 4.0.1 for installing Kotlin Multplatform plugin.Īfter installing KMM plugin, Android Studio should be restarted and then we can create a new KMM project. IOS application – an Xcode project that builds into the iOS application. Uses Gradle as a build system.Īndroid application – a Kotlin module that builds into the Android application.

Builds into an Android library and an iOS framework. Shared module – a Kotlin module that contains common logic for both Android and iOS applications. Components of Kotlin MultiplatformĪ basic KMM project has the following structure and components. For Android, Common Kotlin code is converted in Gradle library that can be used in any Android Project. It allows developers to share knowledge domains and reduce the duplication of native code.Ĭommon Kotlin code is converted into an iOS framework that can be used as any other existing iOS framework in Xcode. Kotlin allows a high level of reusability between developers. KMM enforces modularization, thus by forcing mobile app developers to write code in such a way that separates business logic from UI. With Kotlin Multiplatform Mobile, you can build mobile applications for multiple mobile platforms by sharing code, such as business logic, connectivity etc between Android and iOS. Sharing code between multiple mobile app development platforms is one of the major use cases of KMM. Kotlin Multiplatform Mobile is a feature that enables you to use one codebase to write the business logic of iOS and Android apps.
