[Question] Connecting android with web client

[Tiffceet]

Hi, I am currently developing an android client(android native app) and a web client(js), which the android client will share its screen to the web client via webrtc and I am using this library.

In the web client I am using https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection I encountered issue where after the android client calls .addTrack(), the web client does not trigger ontrack event, I am not sure what I did wrong and I have no idea how to debug/troubleshoot.

Asking if anyone have a working project example where connection is done between android client and a web client. Recommendations on how to troubleshoot /debug is greatly appreciated
