Request SOAP response comes empty

[AlyssonPHN]

Version: 3.6.4 On request on Android onRestart sometimes SOAP response comes empty.

Requests work well, but sometimes when app inative or device gets locked, when returning to app, the request comes with empty value.

I debugged the web service and at this time the request didn't even reach the web service

`SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

XMLOutputter xmOut = new XMLOutputter();

if (PARAMETRO != null) {
    Request.addProperty("sReq", xmOut.outputString(PARAMETRO));
}

SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11);

//soapEnvelope.dotNet = true;
soapEnvelope.dotNet = false;

soapEnvelope.setOutputSoapObject(Request);
Log.i("Requisicao", xmOut.outputString(PARAMETRO));
System.setProperty("http.keepAlive", "false");

HttpTransportSE aht = new HttpTransportSE(URL, 10000);
aht.call("\"\"", soapEnvelope);

// retorno = (SoapPrimitive)soapEnvelope.getResponse();
msg = soapEnvelope.getResponse();

msg = soapEnvelope.bodyIn;`

this is called within a thread.
