Task :app:transformNativeLibsWithMergeJniLibsForDebug FAILED

Question

I am working with react native and every time I build a new project it seems to work on my device , but whenever I try to restart it It is giving me 1 or more errors

I have tried looking for solutions on github but none of them are clear I will post the entire error message here.

Running the cleaning task solved the problem for me. In your project's android dir, run gradle wrapper with 'clean'

cd android && ./gradlew clean

Then you can go back to project dir and try running again.

cd .. && react-native run-android

Thanks, working for me. Except I had to run `gradlew clean` without the dot slash. – ViktorMS Mar 01 '20 at 10:05
This will work but you need to clean every time you run or else it will fail again – ßiansor Å. Ålmerol Jun 30 '20 at 01:20

go to android/app/build.gradle add the following under android

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

Running the cleaning task solved the problem for me. In your project's android dir, run gradle wrapper with 'clean'

cd android && ./gradlew clean

Then you can go back to project dir and try running again.

cd .. && react-native run-android

This should be the accepted answer because after adding these code I can run the app without cleaning the gradlew. — Eaten Taik, Sep 24 '20 at 01:04

Clean project working for me

A react-native Project is about one XCode Project and one Android Project. (pure js code no need to do clean)

So what are you need would be

Clean XCode Project with

$ cd ios
$ xcodebuild clean
$ cd .. && react-native run-ios

And then clean Android Project with

$ cd android
$ ./gradlew clean
$ cd .. && react-native run-android

You can simply write a batch file for it.

Go to android/app/build.gradle and add the following thing under android:

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

  }
}

Then run it again. If your using react native i suggest you to close npm console and run it again.

AAR libraries were not linking to the Main application from Bridge Project.

Solution:

implementation files(‘libs/sdk-5.0.0.aar’)

Instead of

implementation(name:'sdk-5.0.0', ext:'aar')

I faced another issue related to AAR file import into the android project. https://stackoverflow.com/a/58602329/3197778
