Cannot build app if using both voice and video

[gsanthosh91]

Hello guys,

When I trying to build a project with Twilio voice and video call in a single project I am getting an error like
Duplicate class org.webrtc.CalledByNative found in modules libwebrtc.jar (com.twilio:video-android:4.1.2) and libwebrtc.jar (com.twilio:voice-android:3.0.0)

both libraries having libwebrtc.jar, don't know how to exclude in one lib or merging them.

Gradle

implementation 'com.twilio:video-android:4.1.2'
implementation 'com.twilio:voice-android:3.0.0'

Hey @gsanthosh91, thanks for reaching out. Unfortunately at this time our SDK's are not side by side compatible. This means you can't use our video and voice SDK together in the same project. This is due to a WebRTC build time complexity that we haven't scheduled to fix on our roadmap yet. TLDR; this isn't supported.. yet!

If there's a specific use case that you're trying to accomplish we would love to help out and make sure you can get the functionality you need. Would be more than happy to answer any follow up questions :)

[miken01]

Is there any workaround? From my tests older versions of either library are not compatible with iOS when using current versions. Also, I'd imagine this is a very common scenario as I'd believe most people who want VoIP calling in their apps also want the ability to have a video chat. Like every other chat application in the world.

How in the world can a company such as Twilio not have a fix for this on the roadmap? Again, this is very common and insane to think your business team is ok with this approach.

Hey @miken01

I definitely empathize with your frustrations about side-by-side support. I would like to clarify that side-by-side support is on our roadmap. Please follow #340 for any updates or relevant information related to that effort.

I wanted to follow up on this comment.

From my tests older versions of either library are not compatible with iOS when using current versions.

Can you provide more details and file another issue related to this problem? I would like to know more about these compatibility issues.

Thanks!

I am getting around this limitation by using twilioVoice 2.1.0
