More Than One File Was Found With Os Independent Path 'lib/armeabi-v7a/libarcore_sdk_jni.so'

I know there is a few similar questions on SO, but it does not work for me... I created Android lib, that use ArCore. It was a question on SO how to don't include .so file if I use

Solution 1:

You've likely added the shared .so files and build from source (or reference them otherwise).

One cannot do both at the same time, so you'd either need to build from source and delete those .so files - or delete the arcore-android-sdk module and keep the .so files. Java dependencies might also pull in native assembly, while that part of the build.gradle is missing (just browse AR core in the "External Libraries" to see what it contains, in case it exists there). Using pre-built libraries generally builds quicker and saves time - which is suggested, unless needing to edit cpp sources.

Usually one can provide the dependencies alike in this build.gradle:

dependencies {
    implementation "com.google.ar:core:1.13.0"
    natives "com.google.ar:core:1.13.0"
}

// Extracts the shared libraries from aars in the natives configuration.// This is done so that NDK builds can access these libraries.task extractNativeLibraries() {
    // Always extract, this ensures the native libs are updated if the version changes.
    outputs.upToDateWhen { false }
    doFirst {
        configurations.natives.files.each { f ->
            copy {
                fromzipTree(f)
                into arcore_libpath
                include "jni/**/*"
            }
        }
    }
}

tasks.whenTaskAdded {
    task-> if (task.name.contains("external") && !task.name.contains("Clean")) {
        task.dependsOn(extractNativeLibraries)
    }
}

Such Gradle task could also be the reason for the duplicates, when it's not configured properly. packagingOptions are in every case the wrong approach, when the linker already doesn't know which one to link.
