Duplicate class error when including both React Native and Spectrum

[vyphan]

React Native version: 0.59.8
Spectrum version: 1.1.0

Tried the following, but it didn't help:

    implementation('com.facebook.spectrum:spectrum-default:1.1.0') {
        exclude group: 'com.facebook.spectrum', module: 'fbjni'
    }

1 exception was raised by workers:

Hey @vyphan

Thanks for reporting this issue. We've looking into this. I don't have a timeframe to share just yet but will update you as things move forward.

fbjni has been open sourced here. It would likely make sense to make both spectrum and react native use this version to avoid conflicts.

@vyphan you can exclude spectrum-fbjni module

    implementation("com.facebook.spectrum:spectrum-default:$spectrum") {
        exclude group: 'com.facebook.spectrum', module: 'spectrum-fbjni'
    }

then include independent fbjni library, follow set_up

I've tried the above without success. At runtime, I hit the following SoLoaderError after following instructions above to exclude: Java.lang.NoClassDefFoundError: Failed resolution of: Lcom/facebook/jni/FbJniSoLoader$SoLoaderWrapper; at com.facebook.spectrum.SpectrumSoLoader.init(SpectrumSoLoader.java:52)

I copied the source to project. FbJniSoLoader
