而当缺少最后一行：08-02 16:20:13.836 D/WooGeen-PeerConnectionChannel( 2980): onIceConnectionChange:CONNECTED

时，publish会既没有成功、也没有失败、也没有异常。 

请问是什么问题，该如何解决？

什么情况下会缺少最后一行？

如果没有最后一行 那么ICE connection state会变为什么状态？

过程结束后再没打印新的onIceConnectionChange，ICE connection state应该还是CHECKING。

ps：我是用的MCU方式，Android端与web端进行音视频通信。web端发送信令，Android端收到相应信令后再发布视频。一般出现这种情况后，过一会再publish，或者刷新web页面后再尝试，可以恢复正常publish。
