I am trying to have both jitsi and opentok in my android application, and switch them accordingingly.

These are my build.gradle(app) dependencies

//opentok dependency used

implementation files('libs/opentok-android-sdk-2.15.2.aar')

//jitsi dependency used

implementation ('org.jitsi.react:jitsi-meet-sdk:2.5.0')

My build failed with an error like this

Good question. Did you find a solution? – Premolar 15/5, 2020 at 17:18

In my case I resolved the problem with remove some library :Make sure that you are used two library (one in the implementation in your gradle and other is a library so it produces a duplication error)

implementation group: 'org.webrtc', name: 'google-webrtc', version: '1.0.19742'
implementation files('libs/autobanh.jar')

In your case make sure to remove one of two library :((opentok-android-sdk-2.15.2.aar) and jetified-react-native-webrtc-1.75.2-jitsi-2994175-runtime.jar)

Solution: Remove the second and invalidate the cache and restart and enjoy :)

Both of these dependencies use WebRTC with them and imports org.webrtc with them, The best way I can suggest is to use Opentalk source code files (Instead of the aar dependency, if available) and use those files and use webrtc dependency that comes with the Jitsi itself. Considering you cant use Jitsi source code as its first compiled with react native dependencies.

WebRTC increases your app side drastically. You wouldn't want to import it twice anyways.

You are looking for managing the Transitive Dependencies, and the generic way to solve the clashing problem, is to exclude the transitive dependency from one of the dependencies, that brought it:

dependencies {
  compile('com.example.m:m:1.0') {
     exclude group: 'org.unwanted', module: 'x 
  }
  compile 'com.example.l:1.0'
}

You can read more at dependency management of Gradle.

This can be a solution but this will not work if both the dependencies are using different versions for WebRTC. – Elielia 31/3, 2021 at 15:14
