Why use in HttpTransportSE.java the property conection-closed? In android 4.0 this cause a issue over 3g that close the socket, but if use conection keep-alive this works fine.

Try using KeepAliveHttpsTransportSE .. the default class needs to close the connection since it does otherwise not work with older android versions..

I use with android 2.3 and android 2.2 and with connection open works fine.

Hi ,

I think that the KeepAliveHttpsTransportSE it is not well implemented. Currently is setting the connection header when you call to the method getServiceConnection

serviceConnection.setRequestProperty("Connection", "keep-alive");

But as this calls is extending from HttpsTransportSE, when you call the method call, it will override your header:

    ServiceConnection connection = getServiceConnection();

    connection.setRequestProperty("User-Agent", USER_AGENT);
    // SOAPAction is not a valid header for VER12 so do not add
    // it
    // @see "http://code.google.com/p/ksoap2-android/issues/detail?id=67
    if (envelope.version != SoapSerializationEnvelope.VER12) {
        connection.setRequestProperty("SOAPAction", soapAction);
    }

    if (envelope.version == SoapSerializationEnvelope.VER12) {
        connection.setRequestProperty("Content-Type", CONTENT_TYPE_SOAP_XML_CHARSET_UTF_8);
    } else {
        connection.setRequestProperty("Content-Type", CONTENT_TYPE_XML_CHARSET_UTF_8);
    }

    connection.setRequestProperty("Connection", "close");
    connection.setRequestProperty("Accept-Encoding", "gzip");

The way to achieve the change on the header is by actually calling the method call, passing as parameter the list of header including the one for Connection.

Actually i am working on a pull request with some changes to improve the performance and memory usage (specially during creation of dump info for debug)

Sounds great. I am looking forward to your enhancements.

Fixed in 3.0.0-RC.3
