React-native-webrtc: Shared object loading issue on Android x64

[MicronXD]

I'm came across issues with react-native failing to load .so files on Android x64 when react-native-webrtc is added to a fresh project.

When the application starts up, it's looking for an x64 version of libgnustl_shared.so which I think is purposefully omitted by the default /app/build.gradle in a fresh react project:

    defaultConfig {
        ...
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }

I experimented with tweaks to build.gradle and gradle.properties, but couldn't get the app to live through loading all .so files.

After reverting and starting from scratch, I upgraded gradle to 2.14 and the build started failing.
gradle began complaining that libjingle_peerconnection_so.so was missing from the arm64 directory somewhere in /node_modules/react-native-webrtc/build/......

---

Starting from a fresh project:

> react-native init Demo
> cd Demo/
> react-native run-android

> npm install react-native-webrtc --save
> react-native link
-  rnpm-install info Linking react-native-webrtc android dependency
-  rnpm-install info Android module react-native-webrtc has been successfully linked 
-  rnpm-install info Linking react-native-webrtc ios dependency 
-  rnpm-install info iOS module react-native-webrtc has been successfully linked 
> react-native run-android

It launches and dies immediately:

You may want to look at https://github.com/jitsi/jitsi-meet-react/commit/30a9ca40750f6a01a5eae0f8fa5c428ce541b147 where I've fixed the above for the jitsi/jitsi-meet-react project.

Taking a look now! I appreciate the direct commit link!

That's exactly what I was looking for. I didn't realize the ndk abiFilters didn't automatically exclude the unassociated .sos. This was my first time using gradle and you probably just saved me hours more of experimenting with it.

I can't thank you enough!!
