Execution failed for task ':app:mergeDebugNativeLibs'. in react native

Question

I installed react-native-pdf and now when I run "npx react-native run-android", it fails with the following:

* What went wrong:
Execution failed for task ':app:mergeDebugNativeLibs'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > More than one file was found with OS independent path 'lib/x86/libc++_shared.so'

Can anyone help me use the package react-native-pdf?

Answer 1

I had the same issue and i resolved it by adding the following to android/app/build.gradle

android {

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

/** rest of your code here **/

}

does anyone know why do we need to do this? i really dont like gradle tool, there is no explanation... – Jolt

Gives the impression that including the react native pdf reader library somehow introduces other versions of these files and you're telling the compiler which ones to look at or something? – Mra

This feels like a hack... – Cylinder

Answer 2

add this to your app/build.gradle

android {
   // yout existing code
   packagingOptions {
        pickFirst '**/libc++_shared.so'
        pickFirst '**/libfbjni.so'
    }
}

Thanks.. it was just a stale environment. Running flutter -clean worked. – Rhody

Answer 4

Add this code to "/android/app/build.gradle"

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

So run this on the terminal

$ cd android/
$ ./gradlew cleanBuildCache
$ cd ..
$ sudo npx react-native run-android

Answer 5

For us, it was caused by react-native-pdf.

So either, eject the project and update build.gradle same as other answers say or, get rid of it if not used or you may replace it with rn-pdf-reader-js

Which solution did you go with? Had you updated your Gradle file if yes? what changes were needed exactly? – Esthonia

We used rn-pdf-reader-js. It's much more better – Himself

rn-pdf-reader-js is only available for expo projects; if you're running a CRA build you can't use it it seems – Cylinder

Answer 6

For me its gradle cache issue, I fixed it by running running the following command in the project's root directory:

cd android

and after

./gradlew clean

Add this code to "/android/app/build.gradle"

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

Answer 8

I had the same issue in flutter and "pickFirst" worked fine but its important to have that in the main app build gradle not in the plugin one.

i changed minSdkVersion to 21 in "android/app/build.gradle".

defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.custom_epub_view"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

android build.gradle file under allprojects add following

   configurations.all {
   resolutionStrategy {
   force 'com.facebook.react:react-native:0.65.2' //select Version you used
   }
}
