Question

I am trying to consume a .net web service, and get the following error when I run it(debug) from my phone

java.lang.NoClassDefFoundError: javax.microedition.io.Connector

I get the error when I make the call to the transport object

ht.call(SOAP_ACTION, soapEnvelope);

while in the eclipse ide, the (context sensitive model) does not show this in the object model when i try to add it i only see javax.microedition.khronos.* , no javax.microedition.io, which confuses me more.

When I try to debug this in the emulator, I only get a VerifyError

        private static final String SOAP_ACTION = "http://ikonicsoft.com/CheckTrial";
private static final String METHOD_NAME = "CheckTrial";
private static final String NAMESPACE = "http://ikonicsoft.com";
private static final String URL = "http://ikonicsoft.com/WebService.asmx";

     SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);
    request.addProperty("deviceid", deviceid);

    SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    soapEnvelope.dotNet = true;
    soapEnvelope.setOutputSoapObject(request);

    HttpTransport ht = new HttpTransport(URL);
    Boolean bValid = false;
    try{
        ht.call(SOAP_ACTION, soapEnvelope);
        Boolean result = (Boolean) soapEnvelope.getResponse(); 

        if((Boolean)result){
            bValid = true;
        }else{
            bValid = false;
        }

    }catch(Exception e){
        e.printStackTrace();
        bValid = false;

    }

let me know if you need more info

thanks in advance

Solution

Ok, it helps to download and install the correct ksoap2 package. I found the correct package for android development at:

ksoap2-android-assembly-2.4-jar-with-dependencies.jar

OTHER TIPS

The Android SDK does not provide the javax.microedition.io package. Take a look of this for further reference: Package Index

I had a similar problem where Android Studio could not recognize all my org.ksoap2imports. It was solved by restarting Android Studio.
