What version of WebRTC does this library use on Android?

I’m trying to build libwebrtc.jar from source so I can modify it, but it crashes when it’s built with arm and the x64 configurations. Is there a specific branch / release of webrtc I need to be using in order to have it successfully link to this library?

Nevermind, looks like it’s M94, based on the commit of the .placeholder item in the repo:
