react native v0.66.3 with reanimated not supported

[arasrezaei]

Hi there,
thanks for this great package,
I tried to test reanimated with V8 but it crushes the app while opening:

FATAL EXCEPTION: create_react_context

java.lang.UnsatisfiedLinkError: dlopen failed: library "libjsc.so" not found

FATAL EXCEPTION: create_react_context

I also tried your fork of reanimared (with changing reanimated arr from v0.65 to 0.66 :)) and this time got this error this time:

FATAL EXCEPTION: create_react_context

is it possible to fix this?

Try removing exclude "**/libjsc.so" from your android/app/build.gradle

Thanks, but with this method Javascript thread runs with V8 and for example reanimated worklets run with JSC. (Am I right?)
And having two engines will result in a large app size!

I got the same exact error but with v0.65 of react-native-v8. Any help appreciated!

@Kudo Do you know how to solve this? Thanks

[lkinasiewicz]

@Kudo I have already made the necessary changes here: https://github.com/lkinasiewicz/react-native-reanimated/commits/v8/2.3.1 - the last two commits.
Please let me know if you can create v8/2.3.1 branch in your repo so that I can make a pull request, or you can just cherry-pick my changes. I have tested this with RN 0.66.3 and works on Android (v8), Android TV (v8) and iOS (jsc). 0.65.2 should also work, but I haven't checked.

If anybody needs it now, you can use it this way:

• clone my repo
• make sure that you have wget, gradle and other android tools installed
• run yarn
• run ./createNPMPackage.sh
• move the generated tar archive wherever you want and add it to your project, e.g. from your project's directory: yarn add ./react-native-reanimated-2.3.1.tgz; yarn

This is so painful to keep react-native, react-native-reanimated, and react-native-v8 all in sync.

I hope the reanimated team can officially support v8 soon. It's been months and haven't heard anything..

0.67 just got published - has anyone tried to see if it works with reanimated?
