呼び出しコード (Android アプリケーションから):
private final String NAMESPACE = "http://webservices.pcp/";
private final String URL = "http://127.0.0.1";
private final String SOAPACTION = "";
private final String METHOD = "ValidarUsuario";
String user = pars[0];
String password = pars[1];
SoapObject request = new SoapObject(NAMESPACE, METHOD);
SoapSerializationEnvelope sobre = new SoapSerializationEnvelope(SoapEnvelope.VER11);
sobre.dotNet = false;
request.addProperty("login", user);
request.addProperty("password", password);
sobre.setOutputSoapObject(request);
HttpTransportSE transporte = new HttpTransportSE(URL);
try {
transporte.call(SOAPACTION, sobre);
} catch (IOException e) {
// JOptionPane.e.printStackTrace();
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
SoapObject resultado = null;
try {
resultado = (SoapObject)sobre.getResponse();
} catch (SoapFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//comprobar si devuelve un usuario nulo o no
Usuario usu = new Usuario();
usu.IdUsuario= resultado.getProperty(0).toString();
usu.Nombre = resultado.getProperty(1).toString();
usu.Apellidos = resultado.getProperty(2).toString();
usu.Rol = resultado.getProperty(3).toString();
usu.Centro=resultado.getProperty(4).toString();
起動された例外はXmlPullParserExceptionであり、実際、例外をキャッチした後の変数resultadoはまだ null です。
Web サービスは正しく呼び出されているようですが、例外が発生します。
私は何か間違ったことをしていますか？

(MainActivity はアプリケーションの「ベース」アクティビティです。コードは AsynkThread 内で実行されます。これは、メイン スレッド AccesoCuentaActivity で実行された場合、それが起動するためですNetworkOnMainThreadException)
