EMConnectionEventHandler class

服务器连接监听类。

对于不稳定网络条件下的onDisconnected情况，您不需要手动重新连接， SDK会自动处理。

添加 connection event handler:

  EMClient.getInstance.addConnectionEventHandler(UNIQUE_HANDLER_ID, EMConnectionEventHandler());

移除 connection event handler:

  EMClient.getInstance.removeConnectionEventHandler(UNIQUE_HANDLER_ID);
