Android 警告：忽略匿名内部类（org.ksoap2.transport.KeepAliveHttpsTransportSE$1）的InnerClasses属性

当使用

ksoap2-Android-assembly-2.5.8-jar-with-dependencies.jar将Android项目编译为引用库（外部jar）时，我收到以下警告：

[2012-03-20 11:50:50 - AddressBook] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.ksoap2.transport.KeepAliveHttpsTransportSE$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

我正在尝试从android客户端访问EWS SOAP服务，我的代码是：

String NAMESPACE = "http://schemas.microsoft.com/exchange/services/2006/messages";

String SOAP_ACTION = "http://schemas.microsoft.com/exchange/services/2006/messages";
String METHOD_NAME = "GetUserAvailability";
String URL = "https://vpnqrd0302.outlook.com/EWS/Exchange.asmx";

        String result = null;
        Object resultRequestSOAP = null;

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);

        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.debug = true;


        List<HeaderProperty> headerList = new ArrayList<HeaderProperty>();
        headerList.add(new HeaderProperty("Authorization", "Basic "
                + org.kobjects.base64.Base64
                .encode("temp@tempsuer.onmicrosoft.com:Password1"
                                .getBytes())));

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope, headerList);

            String requestDumpString = androidHttpTransport.requestDump;
            System.out.println("requestDump : " + requestDumpString);


            resultRequestSOAP = envelope.getResponse(); // Output received

            System.out.println("resultRequestSOAP : " + resultRequestSOAP);

            result = resultRequestSOAP.toString(); // Result string

            System.out.println("OUTPUT : " + result);
        } catch (Exception e) {
            e.printStackTrace();
        }

我知道这是一个老生常谈的问题，但如果有人像我一样在这里犯了错误：您提到的警告是由一个匿名的内部类以及ksoap2是使用Java1.3兼容性编译的事实（我认为是为了与J2ME兼容）引起的。除非您在这些类上做一些反射工作（甚至在这种情况下：仅当您检查某个类是否是内部类时），否则可以安全地忽略此警告

更好的是，这个特别的警告是通过ksoap2 android的2.6.4版修复的（请参阅）

您的错误与此完全无关，更可能是由于您试图调用的Web服务使用不当造成的。
我看到了这一点，通常的答案是忽略内部类警告，因为这是包含jar文件的结果。尽管在您的情况下，您可能希望获取源代码并将其编译到代码中。
