Pre-built native libraries and jar dependency

[Aldoukfm]

Is there a way to add local pre-built native libraries to /jniLibs and local jar dependencies for the Kotlin side? The swift side is implemented normally and Kotlin side use // SKIP extern handled by the pre-built library.

I've tried configuring them in the skip.yml, manually inserting my libs folder in the generated output folder of the module and re-run the project.

build:
  contents:
    - block: 'android'
      contents:
        - block: 'sourceSets'
          contents:
            - block: 'named("main")'
              contents:
                - 'jniLibs.srcDirs("libs")'
    - block: 'dependencies'
      contents:
        - 'implementation(fileTree(mapOf("dir" to "libs", "include" to listOf("*.jar"))))'

When I call

#if SKIP
System.loadLibrary("HelloWorldJNI")
#endif

inside the module, it fails with java.lang.UnsatisfiedLinkError: dlopen failed: library "libHelloWorldJNI.so" not found.

That looks to me like it should work. In fact, I've just been working on a project that does almost exactly the same thing, and I am able to load the libraries with System.loadLibrary.

What does your libs folder look like? Does it contain sub-folders for each of the supported architectures? And if you look at the .apk that is created, do you see the shared objects being included? E.g., something like:

% unzip -t ./.build/Android/app/outputs/apk/debug/app-debug.apk

Archive:  ./.build/Android/app/outputs/apk/debug/app-debug.apk
    testing: META-INF/com/android/build/gradle/app-metadata.properties   OK
    testing: lib/arm64-v8a/libHelloWorldJNI.so   OK
