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.

Answer 1

转到 android/app/build.gradle 在 android 下添加以下内容

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'  
+   }
}

运行清洁任务为我解决了问题。在您项目的 android 目录中，使用“clean”运行 gradle 包装器

cd android && ./gradlew clean

然后您可以返回项目目录并再次尝试运行。

cd .. && react-native run-android

Answer 2

运行清洁任务可以为我解决问题。在项目的android目录中，使用“ clean”运行gradle wrapper

cd android && ./gradlew clean 

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

cd .. && react-native run-android
