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

问题

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

    }

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

    // call regular ndk-build(.cmd) script from app directory

        } else {
            commandLine 'ndk-build', '-C', file('src/main').absolutePath
        }
    }

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

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    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 ?

回答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
}

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

回答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

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:

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)

I just want to add to Nonos answer that I think I received this issue after running ndk-build within my app/jni directory, and then running ./gradlew installDebug from the top-level directory of my Android NDK project. So doing an ndk-build clean in app/jni before doing another Gradle build did indeed solve the problem.

回答6:

in my case adding these fixed the issue to build.gradle app level module

packagingOptions {
    pickFirst 'lib/armeabi-v7a/libblasV8.so'
    pickFirst 'lib/mips/librsjni.so'
    pickFirst 'lib/x86/libblasV8.so'
    pickFirst 'lib/mips/libRSSupport.so'
    pickFirst 'lib/mips/libblasV8.so'
}

but in your case library names could be different so replace them with your library names
