The Kotlin SDK for Jellyfin implements the Jellyfin API to easily access servers. It is currently available for the JVM and Android. Developer documentation is available at kotlin-sdk.jellyfin.org.

We welcome contributions to the SDK. Open an issue or ask in our official chats if you plan to make bigger changes.

To validate binary compatibility we use the Binary compatibility validator tool from the Kotlin team. When creating pull requests the api files need to be updated. Use the apiDump Gradle task to generate the api files. Add the changes from this command to a separate commit to make the review process easier.

The SDK includes two example projects, the kotlin-cli and java-cli, to test various larger functions like server discovery. Besides that we use unit tests to test smaller components, these can be executed with the allTests Gradle task. We recommend adding new tests for changes to the code.

It is also possible to test a new version of the SDK in your own app. Use the publishToMavenLocal Gradle task to publish the SDK to your local system, afterwards you can add mavenLocal() as repository and use the latest-SNAPSHOT version for the SDK. This process is simplified in our official apps by adding an option to the gradle.properties file.
