I have updated React Native to 0.60-RC2, migrated to AndroidX using the Android Studio refractor and used the jetifier mentioned here: https://github.com/react-native-community/discussions-and-proposals/issues/129

After doing this, I get the error library "libjsc.so" not found when running react-native run-android. i get the same error when running a release APK.

The stacktrace is:

What is the libjsc.so file and how do I solve this error?

Add below in your app/build.gradle

// On top of the file

def useIntlJsc = false

//inside dependencies

 if (useIntlJsc) {
        implementation 'org.webkit:android-jsc-intl:+'
    } else {
        implementation 'org.webkit:android-jsc:+'
    }

    I actually deleted the old project, created a new one from `react-native init` and copied my code onto the new project and it worked. So I can't test this fix. If you are 100% sure this works, then I'll mark this as accepted. – khateeb Jun 27 '19 at 06:59
  • had same problem yesterday, this is how I fixed. With new project you will get above setup as default. You can validate in your generated app/build.gradle – Bhaskar Gyan Vardhan Jun 27 '19 at 07:54

    This gets rid of `libjsc.so` error but now I'm getting `libgnustl_shared.so` not found on a fresh new RN 0.60 RC2 project. – Can Poyrazoğlu Jun 27 '19 at 11:06

    This solution does not work. I get /com.simplewebview E/SoLoader: couldn't find DSO to load: libjscexecutor.so caused by: dlopen failed: library "libgnustl_shared.so" not found /com.simplewebview E/AndroidRuntime: FATAL EXCEPTION: create_react_context Process: com.simplewebview, PID: 26654 java.lang.UnsatisfiedLinkError: couldn't find DSO to load: libjscexecutor.so caused by: dlopen failed: library "libgnustl_shared.so" not found – Krishnan Sriram Aug 07 '19 at 15:23
  • Can anyone sharing the working build.gradle and the package.json? – red-devil Oct 30 '19 at 16:31

    Getting the same issue with `libgnustl_shared.so`. Does anyone have a solution and a reasonable explanation as to why it's not in the react-native docs? – Chris Oct 08 '20 at 20:34
  • Perfect. Solved my issue. – Satish Jul 14 '21 at 13:52

I had this issue too. I needed to update the jscFlavor variable inside the build.gradle file from this:

def jscFlavor = 'org.webkit:android-jsc:+'

To this:

def jscFlavor = 'org.webkit:android-jsc-intl:+'

Cheers.

What solved for me was change build.gradle updating packagingOptions to:

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

    I don't see any of that in my build.gradle. Is this part of a fresh setup of react-native? https://react-native-community.github.io/upgrade-helper/?from=0.61.5&to=0.63.0 – Chris Oct 05 '20 at 16:24
  • @Chris I don't think so. But it's something that you are asked to add if you installed react-native-pdf: https://github.com/wonday/react-native-pdf/#android-installation - it might be that the paths are incorrect / doesn't include JSC for a given architecture, so when you run it on that particular phone/architecture, it's a valid app... just not for that phone, so it crashes because it's missing the JSC (javascript engine) – Seph Soliman Jun 07 '23 at 18:10

I encountered a slight variation of this bug, where I had added a third buildType to my gradle config, 'releaseStaging'

The fix in this instance was to add the following line to dependencies in app/build.gradle

releaseStagingImplementation files(hermesPath + "hermes-release.aar")

Okay ! In the recent versions of react native till today this issue is occurring and is being reported in the crashlytics that you integrate within the app or you can see it in the logs.

This issue only comes when you have Hermes engine enabled.

Here is my fix for this I was facing this issue, in my case Hermes was needed so, I managed to fix this "libjsc.so" not found by installing the jsc-android package from npm. Here is the link.

Please NOTE : Refer to the docs of this package for proper installation as per your react native version

clean gradle and re run the entire app this issue will be gone.

In my case, This error was related with react-native-screen and adding following following two lines to dependencies section in android/app/build.gradle fixed the issue for me

implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0-alpha02'
