We believe that an intention to make an interface applicable for SAM conversion should be explicit. If the behavior for a certain platform needs to be modified, you can use a format like compilerOpts.osx or compilerOpts.linux to provide platform-specific values to the options. Unlike Java, Kotlin will not allow a SAM conversion for every interface with one single abstract method. This command will produce a png.klib compiled library and png-build/kotlin directory containing Kotlin source code for the library. It turned out, however, that function types and typealiases don’t cover all the use-cases, and people often had to keep an interface in Java only to get a SAM-conversion for it. The initial idea behind this design was to use function types explicitly for such use-cases. They are the jars of rhe Kotlin/Native world. SAM conversions currently only work for Java interfaces and abstract classes. klib are Kotlin/Native libraries which you can plug and play in any Kotlin/Native project. Using this bindings you can develop cross-platform but native-looking GUI programs, written in Kotlin, and compiled to small native executable file. libui is a C lightweight multi-platform UI library using native widgets on Linux (Gtk3), macOS, and Windows. Then the compiler automatically converts the lambda to an instance of the class implementing the abstract member function. kotlin-libui Kotlin/Native bindings to the libui C library. SAM conversion applies if you pass a lambda as an argument when an interface or a class with only one single abstract method is expected as a parameter. The community has requested us to introduce support for SAM conversions for Kotlin classes ( KT-7770). Kotlin 1.4 that is going to arrive in spring 2020 will make another step forward for the Kotlin ecosystem. org/jetbrains/kotlin/kotlin-util-klib/1.4.10. Multiple case studies from companies well-known in the industry show that we are making good progress in this direction.

You need to use a multiplatform library ( rialization) or a native library such as libjson. To accomplish this, we’re going to make it shine on all platforms. Kotlin/Native has no support for Java libraries. Our vision is for Kotlin to be a reliable companion for all your endeavors, a default language choice for your tasks. Use the library base artifact name, such as kotlinx-coroutines-core.During the keynote at KotlinConf, Andrey highlighted our strategic view on the current areas of focus for the evolution of Kotlin, and our plans for Kotlin 1.4 which will be released some time next year. If you use a multiplatform library and need to depend on the shared code, set the dependency only once in the shared source set. To provide serialization I experimented with ktor-client-serialization. If you didn't use the Project Wizard to create your project, you can add the dependencies manually. Could not find ktor-client-serialization.klib Multiplatform thomas.g February 22, 2022, 10:56am 1 I’m trying to introduce KMM to my app project (Android & iOS). When you create a multiplatform project, the Project Wizard automatically adds test dependencies to common and platform-specific source sets. The kotlin.test API is available for multiplatform tests. Learn how to change the default behavior. The Kotlin Gradle plugin will select the appropriate JVM standard library depending on the compilerOptions.jvmTarget compiler option of your Gradle build script. The version of the standard library is the same as the version of the kotlin-multiplatform plugin.įor platform-specific source sets, the corresponding platform-specific variant of the library is used, while a common standard library is added to the rest. Dependency on a Kotlin library Standard libraryĪ dependency on a standard library ( stdlib) in each source set is added automatically. It eliminates the differences between the JVM and Native platforms to provide a consistent developer experience in multiplatform projects. Implementation 'com.example:my-library:1.0'Īlternatively, you can set dependencies at the top level. With Kotlin 1.6.20, you can try the Alpha version of the new Kotlin/Native memory manager.
