问题


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?

MainActivity.java

package com.example.clientnetpositionreport;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {
   EditText e1;
   Button b1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        b1=(Button) findViewById(R.id.btn);
        b1.setOnClickListener(new OnClickListener(){
            public void onClick(View v){

                e1=(EditText)findViewById(R.id.evofclientcode);

               Intent i=new Intent(MainActivity.this,GetReport.class);
               i.putExtra("ClientCode",e1.getText().toString());
               startActivity(i);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

              };

              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);
                  }
              }
              };

    }

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.


回答1:


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");

                    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

@xxeemez-ashu:

I get response, change your GetReport.java with below code

public class GetReport extends Activity {

private static final String NAMESPACE = "http://tempuri.org/"; // com.service.ServiceImpl
private static final String URL = "http://commodities.karvy.com/services/NetPositionReport.asmx";
private static final String METHOD_NAME = "NetPositionReport";
private static final String SOAP_ACTION = "http://tempuri.org/NetPositionReport";
private String webResponse = "";
private Handler handler = new Handler();
private Thread thread;

private TextView textView1;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(1);
    setContentView(R.layout.activity_tv);
    textView1 = (TextView) findViewById(R.id.textView1);

    String title = getIntent().getExtras().getString("ClientCode");

    startWebAccess(title);

}

public void startWebAccess(String a) {
    final String aa = a;
    thread = new Thread() {
        public void run() {
            try {
                Log.d("Req value0R", "Starting...");// log.d is used for
                                                    // debug
                SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

                request.addProperty("ClientCode", "64396");
                request.addProperty("key", "Om$@!#@M^#R");

                Log.d("Req value1", request.toString());

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

                HttpTransportSE androidHttpTransport = new HttpTransportSE(
                        URL);
                androidHttpTransport.debug = true;
                androidHttpTransport.call(SOAP_ACTION, envelope);
                SoapObject objectResult = (SoapObject) envelope.bodyIn;
                webResponse = objectResult.toString();
                System.out.println("response: " + webResponse);

            } catch (SoapFault sp) {

                sp.getMessage();
                System.out.println("error = " + sp.getMessage());

            } catch (Exception e) {
                System.out.println("problem8");
                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);
        }
    }
};

}

save changes and run the application and see the logcat, you will get the data there and enjoy...

let me know if any issue, and please select my answer if its working properly...

try to use my class

package com.example.xmlparser;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.SoapFault;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.util.Log;

import com.example.helpers.Helper;

public class SoapParser {
    private static final String TAG = "SaopParser";

    public String call(String name) {
        String returnString = "";
        SoapObject request = new SoapObject(Helper.TARGET_NAMESPACE,
                Helper.OPERATION_NAME);

        Log.i(TAG, "Getting Name :: " + name);

        // request.addProperty("Celsius", txtCel.getText().toString());

        request.addProperty("companyName", name);

        // PropertyInfo info = new PropertyInfo();
        //
        // info.setType(PropertyInfo.STRING_CLASS);
        // info.setName("companyName");
        // info.setValue(name);
        //
        // request.addProperty(info);

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

        try {
            HttpTransportSE transportSE = new HttpTransportSE(
                    Helper.SOAP_ADDRESS);
            transportSE.call(Helper.SOAP_ACTION, envelope);
            returnString = envelope.getResponse().toString();
            Log.i(TAG, envelope.getResponse().toString());
        } catch (SoapFault e) {
            e.printStackTrace();
            Log.i(TAG, "Getting Exception");
        } catch (Exception e) {
            e.printStackTrace();
        }

        return returnString;

    }
}

Helper.TARGET_NAMESPACE is namespace

Helper.OPERATION_NAME is mwthod name

you can take Refrece for here , here and [here].3




回答4:


I would of commented but I don't have enought rep.

I would try replacing

Object objectResult = (Object)envelope.getResponse();

with

SoapObject objectResult = (SoapObject)envelope.getResponse();

Also I noted that the webservice your pointing to is .aspx but you have envelope.dotNet = false; // Don't you want to change this to true?
