[Android] Error when loading lib: dlopen failed: library "libjsc.so"

[andresesfm]

After following implementation steps in README.md. The app compiles and attempts to launch but crashes with the following exception:

SoLoader: couldn't find DSO to load: libreactnativejni.so caused by: dlopen failed: library "libjsc.so" not found

According to https://stackoverflow.com/questions/43368926/android-reactnative-java-lang-unsatisfiedlinkerrorcould-find-dso-to-load-libre This could be related to a missing 64bit library.

Note that we cannot revert to 32bit since Google will soon enforce 64bit support

Any pointers would be appreciated.

What is your RN version?
Could you please also check your build.gradle if there are any url("$rootDir/../node_modules/react-native/android")?
Please make sure to exclude official RN maven repo and use the react-native-v8 repo instead.
Thanks.

Hello, we are using RN 0.59.9
Yes, there is a reference to that path:

maven {
            // Replace AAR from original RN with AAR from react-native-v8
            url("$rootDir/$NODE_MODULES_DIR/react-native-v8/dist")
        }
        maven {
            // prebuilt libv8.so
            url("$rootDir/$NODE_MODULES_DIR/v8-android/dist")
         }
         maven {
             // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
             url "$rootDir/$NODE_MODULES_DIR/react-native/android"
         }

Removing it causes the following compilation error:

Execution failed for task ':react-native-community_async-storage:compileDebugRenderscript'.
> Could not resolve all files for configuration ':react-native-community_async-storage:debugCompileClasspath'.
   > Could not find com.facebook.react:react-native:0.59.9.
     Required by:
         project :react-native-community_async-storage

At first, I thought it would be something related to that particular project but if I remove that reference then another module fails with a similar error.

By your question about the version, I assume you are thinking that the library was compiled with a lower version of RN. Correct?

[andresesfm]

Or actually, quite the opposite, I just looked at the package.json file and it provides "RN_VERSION": "v0.60.0"

[bhaskarGyan]

@andresesfm react-native version and react-native-v8 version should be same.

[Kudo]

Yes as @bhaskarGyan said, the version should be matched.
Currently, 0.59.x is not supported yet. are there any reasons not to try RN 0.60?

[andresesfm]

Yup, it makes sense. We have a task to update to .60 but since it requires a big overhaul due to the androidx change

[Kudo]

@andresesfm FYI. As there are many people getting frustration to upgrade 0.60 for AndroidX, I did backport RN V8 support to 0.59.10.
yarn add 'react-native-v8@>=0.59.10-patch.0 <0.59.11'
