On the next page, leave the default settings and click Finish to create a new project. In our tutorial, the application name is KmmKtor. Specify a name for your application, and click Next. Select Kotlin Multiplatform App in the list of project templates, and click Next.
In Android Studio, select File | New | New Project. You will need a Mac with macOS to complete certain steps in this tutorial, which include writing iOS-specific code and running an iOS application. Learn how to do this from the Set up an environment section. Prerequisitesįirst, you need to set up an environment for cross-platform mobile development by installing the necessary tools on a suitable operating system. To learn how to create your first Kotlin Multiplatform Mobile application, see Create your first cross-platform mobile app. In this tutorial, we'll create a simple Kotlin Multiplatform Mobile application, which sends a request and receives a response body as plain HTML text. The Ktor HTTP client can be used in multiplatform projects.
In the following example, we’ve defined a Platform object which will need to be defined for each target platform.Creating a cross-platform mobile application Using expect, you add your class/property/etc declaration to your shared module. These platform specific implementations work using the expect and actual keywords. Sharing Code Between Different Build Targets These concrete implementations exist within the specific platform modules, and are then consumed by the native Android and iOS apps as if they were any other module. You might define a common declaration in common code, and then provide a platform specific implementation for both Android and iOS. Imagine you are building an Android and an iOS app. That module is included in your platform-specific projects, and consumed as if it was any other third-party library. Building For Multiple Targetsīusiness logic, data objects, interfaces, repositories, etc can all be defined within a common module. So what exactly is Kotlin Multiplatform? A Kotlin Multiplatform (KMP) project enables the sharing of common code across your various build targets. And while the technology is still rapidly evolving, it’s quickly reaching the point of viability beyond the early adopter audience. Kotlin Multiplatform makes this possible.
Have you tried Kotlin Multiplatform? Have you heard about Kotlin Multiplatform, but aren’t really sure what it’s about?ĭid you know you can use Kotlin to build applications for the web, iOS, Mac, Linux, Android, and more?
