onIceCandidate() never gets called while trying to establish a connection

[suyash192]

I'm trying to use webrtc-java library to create a webrtc data channel between two peers.

1. Relevant code
2. Webrtc Logs

On execution and after calling connect() function of my class I'm observing the following happening:

1. The offer is generated successfully, set as local description, and sent over to the peer.
2. Peer answer is received successfully and set as remote description.
3. onIceCandidate() is never called by webrtc.
4. onRenegotiationNeeded() gets called instead.

I have set multiple STUN servers yet ICE candidates are never being generated.

Am I doing something wrong here?

Any help would be appreciated
