More than one file was found with OS independent path 'lib/x86/libusb.so'

Question

I am using libusb in my android application. When I am trying to build libusb native library then I get below error message, *.so files generated.

Error:Execution failed for task ':app:transformNativeLibsWithMergeJniLibsForDebug'. More than one file was found with OS independent path 'lib/x86/libusb.so'

build.gradle

import org.apache.tools.ant.taskdefs.condition.Os

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 26

    }
    externalNativeBuild {
        ndkBuild {
            path 'src/main/jni/Android.mk'
        }
    }

    sourceSets.main {
        jniLibs.srcDir 'src/main/libs'
        jni.srcDirs = [] //disable automatic ndk-build call
    }

    // call regular ndk-build(.cmd) script from app directory
    task ndkBuild(type: Exec) {
        if (Os.isFamily(Os.FAMILY_WINDOWS)) {
            commandLine 'ndk-build.cmd', '-C', file('src/main').absolutePath
        } else {
            commandLine 'ndk-build', '-C', file('src/main').absolutePath
        }
    }

    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn ndkBuild
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation ('com.android.support.test.espresso:espresso-core:2.2.2', {

    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    compile "org.jetbrains.anko:anko-appcompat-v7-commons:$anko_version"
}

I am on windows machine. Does anyone know what could be the issue ?

Solution 1

I removed jniLibs.srcDir 'src/main/libs' code inside sourceSets.main block. It was creating *.so files twice.

sourceSets.main {
    jniLibs.srcDir 'src/main/libs'
    jni.srcDirs = [] //disable automatic ndk-build call
}

Solution 2

I was having this issue in my React-Native Bridge project after I added AAR files of 3rd party SDK. And I was linking the Bridge into my Main React-native application.

Solution (May differ for you):

Add this in app/build.gradle the Main React-Native application:

android {
    // ...
    packagingOptions {
        pickFirst '**/*.so'
    }
}

• Test the Build on React-Native Bridge project after adding the AAR libraries.
• Clean the React-Native Bridge project
• Clean the React-Native application project
• Remove node_modules and re-install the bridge package into the project.
• Run the application.

I faced another issue related to this (If you include AAR into library project that's not being linked to main application)

Solution 3

you can use like this:

add the following code into build.gradle ,

packagingOptions {
    pickFirst 'lib/armeabi-v7a/your_name.so'
    pickFirst 'lib/arm64-v8a/your_name.so'
    pickFirst 'lib/x86/your_name.so'
    pickFirst 'lib/x86_64/your_name.so'
}

this pickFirst that means : if more than one path matches the first-pick, only the first found will be selected. please click Get more information

Solution 4

In case of react-native add android/app/build.gradle file into andorid : {.....} section this :

packagingOptions {
    pickFirst 'lib/x86/libc++_shared.so'
    pickFirst 'lib/x86_64/libjsc.so'
    pickFirst 'lib/arm64-v8a/libjsc.so'
    pickFirst 'lib/arm64-v8a/libc++_shared.so'
    pickFirst 'lib/x86_64/libc++_shared.so'
    pickFirst 'lib/armeabi-v7a/libc++_shared.so'
}

then use "gradlew clean"

Solution 5

I've seen a similar error running my app after migration to Android Studio 3.0. A build clean solved the issue.

Did not work for me: Error:(25, 1) A problem occurred evaluating project ':app'. > Cannot cast object 'src/main/jni/lib' with class 'java.lang.String' to class 'java.lang.Iterable'

[easy_breezy]

Thanks it worked for me with Android Studio 4.0.1 and NDK version 21.3.6528147

[Summer Sun]

it seems in old gradle version srcDirs is mandatory if you want to pack so into apk

[Amin Keshavarzian]

also worked for a non react problem, thanks

[hong developer]

Where do I execute this command?

[Muhammad Rafeh Atique]

after it I am unable to assemble Debug apk. Means When I assembles debug. its generate apk which is not a debug apk

[Michael N]

Thanks! This helped a lot with FFMPEG.

[Aviraj Patel]

worked for flutter-android studio too.

[Qinghua]

clean build folder fixed

[Naruto Uzumaki]

For react native 0.67 this solution worked, for 0.68 it didn't
