I Am Trying To call Asmx (.net Web Services) From Android Application. But When I am giving data It is Giving Error :
AndroidRuntime(591): FATAL EXCEPTION: Thread-75
AndroidRuntime(591): java.lang.NullPointerException: println needs a message
in logcat showing data is going:
D\Req value1(540): NetPositionReport{arg0=64396; b=Om$@!#@M^#R; }
What Could Be The Problem?

note: The console output is till problem6. That means the value is Null (What I think.).So please keep that in mind.

What Could Be The Problem?
Note: the log.d method is getting string values,so that isn't the problem as was in some related cases.
After read your code I found out many minor mistakes..
I can't write all mistake here so just compare your code with mine code and understood your mistakes.
This is your Asmx Web-Service.
Here you have to pass two input paramater
<ClientCode>string</ClientCode>
<key>string</key>
but you are passing everything wrong..
Your Wrong Code
PropertyInfo fromProp =new PropertyInfo();
fromProp.setName("arg0");
fromProp.setValue(aa);
fromProp.setType(String.class);
request.addProperty(fromProp);
PropertyInfo fromProp2 =new PropertyInfo();
fromProp2.setName("b");
fromProp2.setValue("Om$@!#@M^#R");
fromProp2.setType(String.class);
request.addProperty(fromProp2);
You have to pass like this
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
// simple object access protocol
request.addProperty("ClientCode", aa);
request.addProperty("key", "Om$@!#@M^#R");

request.addProperty("key", "Om$@!#@M^#R");
Log.d("Req value1", request.toString());
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
envelope.dotNet = true;
envelope.bodyOut = request;
// envelope.dotNet = true;
envelope.setOutputSoapObject(request);
Log.d("Req value2", envelope.toString());
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject resultData = (SoapObject) envelope.getResponse();
if (resultData != null)
webResponse = resultData.toString();
else
webResponse = "No Data found.";
System.out.println("webResponse : " + webResponse);
}
catch (Exception e) {
e.printStackTrace();
webResponse = "Connection/Internet problem";
}
handler.post(createUI);
}
};
thread.start();
}
final Runnable createUI = new Runnable() {
public void run() {
if (webResponse != null) {
textView1.setText(webResponse);
} else {
webResponse = "No data provided presently";
textView1.setText(webResponse);
}
}
};
}
This is code is working but I am not getting response may be I am passing wrong value of ClientCode and key
