Android: SSLException I/O error during system call, Connection timed out

I have a function in my android code which send data to the web service using KSOAP. I am able to send data to the service, but sometimes I get an exception: "SSLException I/O error during system call, Connection timed out".

After performing a couple of test my observations are:

  • If wifi/mobile data is already ON and I send data to web service I don't get an exception.
  • I only get it when I just turn wifi/mobile data ON and once its connected when I try to send data.

I am clueless on how to get over this exception. If you can please suggest/guide me on how to overcome this exception would be a great help.

Following is the method used to send data to web service which is called in an ASYNC task.

public String incidentDataToServer(JSONObject incidentJSON) {
        // package the request
        SoapObject Request = new SoapObject(INCIDENT_NAMESPACE,
                INCIDENT_METHOD_NAME);
        String incidentData = incidentJSON.toString();
        PropertyInfo pi = new PropertyInfo();
        pi.setName("IncidentJSonString");
        pi.setValue(incidentData);
        pi.setType(String.class);
        Request.addProperty(pi);

        // set the soap serialization envelope, set it to .net and package
        // the entire request and pass to soap envelope.
        SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        soapEnvelope.dotNet = true;
        soapEnvelope.setOutputSoapObject(Request);

        HttpTransportSE aht = new HttpTransportSE(URL);
        try {

            aht.call(INCIDENT_SOAP_ACTION, soapEnvelope);
            SoapPrimitive resultString = (SoapPrimitive) soapEnvelope
                    .getResponse();

            resIncident = resultString.toString();

        } catch (Exception e) {
            e.printStackTrace();

        }
        return resIncident;

    }

This seems similar to a bug in Android which returns disconnected connections: https://code.google.com/p/android/issues/detail?id=65463.

The ksoap2-android library was affected by this, and your SOAP library may be as well. To quote from the issue:

If you use ksoap for android: 

ArrayList<HeaderProperty> headerPropertyArrayList = new ArrayList<HeaderProperty>();
headerPropertyArrayList.add(new HeaderProperty("Connection", "close"));

And updating your call with .call(SOAP_ACTION, envelope, headerPropertyArrayList).
