Hey @ShadowsHunter, did you get any error codes?

Should look something like this:

E/KinesisVideoSdpObserver: onSetFailure(): Error=Failed to set remote offer sdp: Failed to set remote video description send parameters for m-section with mid='video1'.
E/KinesisVideoSdpObserver: onCreateFailure(): Error=Session error code: ERROR_CONTENT. Session error description: Failed to set remote video description send parameters for m-section with mid='video1'..

In this case of ERROR_CONTENT, it means your device (or emulator) does not support the any of the formats of the media that is being asking for:

 a=rtpmap:0 H264/90000
