在使用ksoap2包调用HttpTransportSE.call方法时遇到IllegalArgumentException异常，问题出现在输入流为null。具体调用代码中设置SoapObject和SoapSerializationEnvelope，并尝试通过HttpTransportSE进行服务调用。错误日志显示在com.ssqposition.position.MainActivity的线程执行时抛出异常。

具体代码
SoapObject soapObject = new SoapObject(namespace, methodName);
soapObject.addProperty(“phone:”, “1”);
soapObject.addProperty(“longitude”, 2);
soapObject.addProperty(“latitude”, 3);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);
envelope.bodyOut = soapObject;
envelope.dotNet = true;
//envelope.setOutputSoapObject(soapObject);
HttpTransportSE httpTransportSE = new HttpTransportSE(Wsdl_Url);
try {
httpTransportSE.call(methodName, envelope);
System.out.println(“调用WebService服务成功”);
} catch (Exception e) {
e.printStackTrace();
System.out.println(“调用WebService服务失败”);
}
