How Android SDK interact with xmpp server

Hello,

I checked android sdk and (if I’m wrong please correct me)I found out, it uses react native library to implement webrtc. before using webrtc to have video/voice, there should be some handshakes that are done by xmpp. also for sending a text message, the text is sent by xmpp.

How android sdk do that?

Check lib-jitsi-meet project, this is what web and mobile uses.
