Android download is not working

[ankhafizov]

how to solve this kind of errors?

Tried, but is not working (and is deprecated, btw):

 packagingOptions {
        exclude("**/*")
    }

Please try to follow the instructions here: https://github.com/bytedeco/gradle-javacpp?tab=readme-ov-file#the-platform-plugin

they are outdated and not sutable for graddle 8.10, kts..

[ankhafizov]

finally solved. I think it worth to add to the readme

[ankhafizov]

val javacpp by configurations.creating

tasks.register<Copy>("javacppExtract") {
    dependsOn(configurations.getByName("javacpp"))

    from(configurations.getByName("javacpp").map { zipTree(it) })
    include("lib/**")
    into("$buildDir/javacpp/")

    android.sourceSets["main"].jniLibs.srcDirs("$buildDir/javacpp/lib/")

    tasks.getByName("preBuild").dependsOn(this)
}

and

    implementation("org.bytedeco:javacv:1.5.10")
    javacpp("org.bytedeco:openblas-platform:0.3.26-1.5.10")
    javacpp("org.bytedeco:opencv-platform:4.9.0-1.5.10")

Now got

when tried: val mat = Mat(height, width)

[saudet]

So, where is libjniopenblas_nolapack.so?

[ankhafizov]

Probably, it should be installed with openblas-platform, shouldn't it?

[saudet]

I mean in your application. Where is it located?

[ankhafizov]

you mean this?

[saudet]

No, that's the source. Where does it end up in your application, after the build?

[ankhafizov]

I have no jniLibs folder at all, after moving to the kts gradle.

Before I had java gradle with code:

 task javacppExtract(type: Copy) {
    dependsOn configurations.javacpp

    from { configurations.javacpp.collect { zipTree(it) } }
    include "lib/**"
    into "$buildDir/javacpp/"
    android.sourceSets.main.jniLibs.srcDirs += ["$buildDir/javacpp/lib/"]

    tasks.getByName('preBuild').dependsOn javacppExtract
}

and it worked:

So you know what you need to do to make it work
