答案 0 :(得分：0)
听起来您的服务不会从您的请求中返回任何内容。也许你应该确保你的SOAP请求是正确的。
答案 1 :(得分：0)
此处生成异常：
result= soapEnvelope.getResponse().toString();
可能你在那条线之前做错了什么。例如。 soapEnvelope可能未正确初始化。或者必须先执行请求？
更确切地说，错误发生在 SoapSerializationEnvelope.java:552 （由上面的此调用执行）。但是，由于您没有发布此文件，我们无法检查。
---编辑---
我在这里找到了这个文件的一个版本：http://code.google.com/p/salesforceandroid/source/browse/trunk/SalesforceAndroid/src/org/ksoap2/serialization/SoapSerializationEnvelope.java?r=93;似乎是该文件的不同版本（因为没有行号552）;但是有一个方法getResonse（）：
public Object getResponse() throws SoapFault {
if (bodyIn instanceof SoapFault) {
throw (SoapFault) bodyIn;
}
KvmSerializable ks = (KvmSerializable) bodyIn;
return ks.getPropertyCount() == 0 ? null : ks.getProperty(0);
}
这应该产生空指针异常的唯一原因是“bodyIn”（内部变量）为null。该变量在parseBody（）方法或该对象的parseXml（）中初始化。因此，在成功执行getResponse（）;
之前，必须首先调用此方法OR：如果这部分由你维护......变量“bodyIn”必须在对象生命周期的其他地方初始化。
答案 2 :(得分：-1)
对我而言，也许这会有所帮助：
if (android.os.Build.VERSION.SDK_INT > 9)
{
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
