从Android客户端连接到我的web服务时遇到问题。在我的MainActivity类中，程序在以下行崩溃：
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
问题是定义上不是方法名称，而是关于命名空间的东西，但我不知道出了什么问题。
GameAndroidUtil：
private static final String NAMESPACE = "http://game.webcentral.pl/";
private static final String SOAP_ACTION = "";
private static final String WSDL_URL = "http://localhost:8080/ReversiGameWS/services/GameWS?wsdl";
MainActivity：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
GameAndroidUtil.testGameWS();
} catch (SoapFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

来自Web服务的我的GameWS.java：
package pl.webcentral.game;
import java.util.HashMap;
@WebService(targetNamespace = "http://game.webcentral.pl/", portName = "GameWS", serviceName = "GameWSService")
public class GameWS {
// Further code
}
我做错了什么？我真的尝试了一切。 Web服务本身工作正常。
更新了LogCat：

答案 0 :(得分：6)
您正在尝试通过将localhost:8080指定为托管服务的系统的地址来连接到Web服务。 Android模拟器在虚拟机（QEMU）内运行。因此，localhost:8080将是模拟器自己的环回地址，而不是系统的地址。
因此，您可以转到Windows中的CommandPrompt获取系统的IP地址，或者只使用http://10.0.2.2:8080/...而不是localhost。
private static final String WSDL_URL = "http://10.0.2.2:8080/ReversiGameWS/services/GameWS?wsdl";
答案 1 :(得分：1)
问题很可能是您尝试在UI线程上执行Web调用。
检查你的logcat，你可能会看到这个错误。
您不需要长时间运行调用（如Web服务调用）而不需要UI线程，并且需要使用AsyncTasks将它们移出线程。
如果不是这种情况，则需要包含logcat输出，以便我们了解更多信息。
答案 2 :(得分：0)
java.lang.VerifyError可能是您在运行时使用的结果。
例如，当我尝试运行针对Xerces 1编译的程序时发生了这种情况，但在类路径中找到了Xerces 2。在运行时找到了所需的类（在org.apache.*名称空间中），因此ClassNotFoundException 不 结果。对类和方法进行了更改，因此在运行时找到的方法签名与编译时的方法签名不匹配。
通常，编译器会标记方法签名不匹配的问题。当加载类时，DVM将再次验证字节码，并在字节码尝试执行不应允许的操作时抛出VerifyError - 比如调用返回String的方法然后存储该返回包含List的字段中的值。
请确保您在编译时使用任何jar或库的正确版本。
