Sounds like you service returns nothing from your request. Maybe you should ensure that your SOAP request is correct.

The exception is generated here:

result= soapEnvelope.getResponse().toString();

Probably you did something wrong before that line. E.g. soapEnvelope is maybe not initialized correctly. Or the request must be executed first?

More exactly the error is in SoapSerializationEnvelope.java:552 (which is executed by this call above). But as you did not post this file, we cannot check that.

--- edit ---

I found a version of this file here: http://code.google.com/p/salesforceandroid/source/browse/trunk/SalesforceAndroid/src/org/ksoap2/serialization/SoapSerializationEnvelope.java?r=93 ; seems to be a different version of that file (as there is no line number 552); But there is a method 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);
}

The only reason why this should produce a null-pointer exception is that "bodyIn" (an internal variable) is null. This variable is initialized either in the parseBody() method or in parseXml() of that object. So this must be called first, before you can successfully execute getResponse();

OR: if this part is maintained by you... the variable "bodyIn" must be initialized elsewhere in your objects life cycle.

Maybe this helps, for me worked:

if (android.os.Build.VERSION.SDK_INT > 9) 
{
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

see Android http connection exception
