Good day, we are currently building a Flutter project for Android and we are using DL4J but when we are trying to create the app bundle we are getting an error as follows: \* What went wrong:  
Execution failed for task ‘:app:packageReleaseBundle’.

> A failure occurred while executing com.android.build.gradle.internal.tasks.PackageBundleTask$BundleToolWorkAction  
> File ‘root/lib/arm64-v8a/include/cblas.h’ uses reserved file or directory name ‘lib’.

From a previous forum post: [ND4J is conflicting with Android dependencies](https://community.konduit.ai/t/nd4j-is-conflicting-with-android-dependencies/2870) someone recommended that we use nd4j-minimal but how can we change our current dependencies to accommodate this? Our current dependencies list is also as follows:  
dependencies {  
//api “org.bytedeco:javacv-platform:$javacvVersion”

```
    implementation (group: 'org.deeplearning4j', name: 'deeplearning4j-core', version: '1.0.0-beta6') {

        exclude group: 'com.google.guava', module: 'guava'
    }

}

```

The reason for a lot of the excludes is because of previous errors we have ran into but have fixed. Thank you for any help regarding this topic 😄

P.S I have also tried looking into potential solutions on the bytedco github repo and will try to incorporate those but if we can find the solution by using nd4j-minimal it would be awesome!

Also to expand on the previous solution given by the bytedco repo. The recommended we use the [Gradle JavaCPP](https://github.com/bytedeco/gradle-javacpp?tab=readme-ov-file#the-platform-plugin) and its platform plugins to natively compile the code from said needed dependencies.

But my issue with that aswell is that they gave an example of their dependencies as follows:

```auto
dependencies {
    implementation group: 'org.bytedeco', name: 'javacv', version: "$javacvVersion"
    javacpp group: 'org.bytedeco', name: 'openblas-platform', version: "$openblasVersion-$javacppVersion"
    javacpp group: 'org.bytedeco', name: 'opencv-platform', version: "$opencvVersion-$javacppVersion"
    javacpp group: 'org.bytedeco', name: 'ffmpeg-platform', version: "$ffmpegVersion-$javacppVersion"
    ...
}

```

But I’m unsure if we can use such dependencies on our project.

Hi, I’m the one who created the topic you mentioned. I was able to fix the issue with nd4j and android with these dependencies

```auto
implementation ('org.nd4j:nd4j-native:1.0.0-M2.1:android-arm64') {
        exclude group: 'org.nd4j', module: 'guava'
        exclude group: 'org.nd4j', module: 'protobuf'
        exclude group: 'org.bytedeco'
    }

    implementation ('org.nd4j:nd4j-native:1.0.0-M2.1:android-arm') {
        exclude group: 'org.nd4j', module: 'guava'
        exclude group: 'org.nd4j', module: 'protobuf'
        exclude group: 'org.bytedeco'
    }

    implementation ('org.nd4j:nd4j-native:1.0.0-M2.1:android-x86') {
        exclude group: 'org.nd4j', module: 'guava'
        exclude group: 'org.nd4j', module: 'protobuf'
        exclude group: 'org.bytedeco'
    }

    implementation ('org.nd4j:nd4j-native:1.0.0-M2.1:android-x86_64') {
        exclude group: 'org.nd4j', module: 'guava'
        exclude group: 'org.nd4j', module: 'protobuf'
        exclude group: 'org.bytedeco'
    }

    implementation ('org.nd4j:nd4j-native:1.0.0-M2.1') {
        exclude group: 'org.nd4j', module: 'guava'
        exclude group: 'org.nd4j', module: 'protobuf'
        exclude group: 'org.bytedeco'
    }

    implementation 'org.bytedeco:openblas:0.3.23-1.5.9'

```

Then I added openBLAS .so files to our jniLibs folder like in the picture. Hope this helps
