Duplicate class error from conflicting WebRTC library in React Native app

I've been looking workaround for the past few days but no avail. I'm using Voximplant only for instant messaging (IM) and wanted to use Sinch for VOIP calls to the other app. As Sinch IM doesn't fit our use case so we used Voximplant for the messaging which I first implemented.

Now I couldn't build with react-native-sinch-voip due to Voximplant SDK also contains VOIP functions, causing both libraries to conflict in WebRTC classes during build.

I managed to solve the conflict in iOS by renaming the CallManager class name but unable to resolve for Android.

I've tried several solution suggested, adding below code to app/build.gradle but couldn't get it work. Not sure if I'm using the right syntax as well. I'm not familiar with native Android, hence seeking for help.

implementation(project(':react-native-voximplant')){
    exclude group: 'com.voximplant', module:'org.webrtc.*'
}

configurations {
    all*.exclude module: 'org.webrtc.AndroidVideoDecoder'
}
Solution

  • Unfortunately, it is not possible to use Voximplant React Native SDK with other SDKs based on WebRTC. Voximplant SDK is based on specific version of WebRTC library with extra patches and excluding WebRTC native library from Voximplant Android SDK will lead to undefined behavior.

    We are currently working on a major update for Voximplant SDK that will allow to use Voximplant messaging API without WebRTC dependency, however it takes several months to complete this version.
