Kotlin-JNI is a powerful Kotlin Multiplatform library designed to simplify and unify JNI (Java Native Interface) development across Android, Desktop (Linux, macOS, Windows), and Kotlin/Native.

It provides a common JNI interface for all supported native targets and includes a KSP module to automatically generate JNI-compatible function stubs, eliminating boilerplate and bridging the gap between your native Kotlin code and the Java world.

I want to express great gratitude to the original creator @DatL4g for the idea and execution. This project indeed makes JNI on Kotlin painless and effortless.

However, since the original repository no longer has a permissive license, this repository had to be created, based on the older, Apache-licensed version.

• Unified JNI API: Write common JNI code for androidNative, linux, macos, and mingwX64 targets.
• Type Conversion Utilities: A rich set of extension functions to effortlessly convert between JNI types and standard Kotlin types (e.g., jstring.toKString(), IntArray.toJIntArray()).
• KSP Code Generation: Automatically generate JNI-compatible C-style function stubs from your idiomatic Kotlin functions using the @JNIConnect annotation.
• Seamless Java Integration: Call your native Kotlin functions directly from Java with standard Kotlin types, just as you would with any other external method.
