Try to access your URL
尝试访问您的网址
http://192.168.0.3:8080/MyWebService/services/WebService?wsdl
from your android browser. If you are getting an xml page, then it's not the network problem. If it's network problem, try restarting your local server and changing firewall and router configurations.
从你的安卓浏览器。如果你得到一个 xml 页面，那么这不是网络问题。如果是网络问题，请尝试重新启动本地服务器并更改防火墙和路由器配置。
