java.lang.Error: Create session description failed: Expect line: v= []

[Raghav-Deo]

I am new to webrtc.The SDP is being sent to me via a browser through a different js webrtc library.I am trying to set the remote description with peer_connection.setRemoteDescription(description, set_session_description_observer);

I am getting the error --> java.lang.Error: Create session description failed: Expect line: v= []

My sdp is : v=0\r\no=mozilla...THIS_IS_SDPARTA

Any help would be greatly appreciated.
