android org.ROS.internal.node.xmlrpc.XmlRpcTimeoutException中的ROS订户错误

我正在从事android上的ROS项目。我可以与主机连接，但当我订阅任何主题时，我会收到这个错误

E/UpdatePublisherRunnable:org.ros.internal.node.xmlrpc.XmlRpcTimeoutException:org.apache.xmlrpc.client.TimingOutCallback$TimeoutException:等待10000毫秒后无响应

我不知道如何解决这个错误。这是我在安卓工作室的日志。请帮帮我
