I've browsed a lot of article regarding consuming .net web service with android but it seems that I can't make it work.

  • I've donwloaded "ksoap2-android-assembly-2.6.2-jar-with-dependencies" and add it in as an external jar in my current project.

  • I've already put uses-permission android:name="android.permission.INTERNET" in the manifest file.

When I debug the program and call the function, the application say's "The application * (*) has stopped unexpectedly. Please try again."

What am I doing wrong? Here's my code:

private static final String NAMESPACE = "http://epson.com.ph/";
private static final String SOAP_ACTION = "http://epson.com.ph/TheMessage";
private static final String METHOD_NAME = "TheMessage";
private static final String URL = "http://10.0.2.2/DataAccess.asmx";

private void getData(){ 
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    //request.addProperty("selectStatement", "SELECT * FROM ALLDETAILS");

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

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
    TextView tv = (TextView)findViewById(R.id.txtPreview); 

    try { 
        androidHttpTransport.call(SOAP_ACTION, envelope); 
        Object result = (Object)envelope.getResponse();

        tv.setText(result.toString()); 
    } catch (Exception ex) { 
        messageBox(ex.getMessage()); 
        } 
}

The logcat errors are:

Please help me, I needed to make this work as soon as possible. Thanks!

Thank you for all your reply, I already got a solution. Just like what Frankenstein says, its slightly the same case on the link that he gave.

I've put a libs folder on the project and import the ksoap jar. I'm just wondering, why is libs folder not automatically included in every project, will the solution work if I had named it with a different folder name.
