问题描述
我正在尝试从Android应用程序调用Asmx(.net Web服务).但是，当我提供数据时，它给出了错误:
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
logp中的
显示数据正在运行:
in logcat showing data is going:
D\Req value1(540): NetPositionReport{arg0=64396; b=Om$@!#@M^#R; }
可能是什么问题?

}
else {

textView1.setText(webResponse);
}
}
};
}
注意:控制台输出直到 problem6 .这意味着值是 为空(我的想法.).请记住这一点.
note: The console output is till problem6. That means the value is Null (What I think.).So please keep that in mind.

可能是什么问题?
注意: log.d方法正在获取字符串值，因此这并不是某些相关情况下的问题.
Note: the log.d method is getting string values,so that isn't the problem as was in some related cases.
推荐答案
在阅读您的代码后，我发现了许多小错误.
After read your code I found out many minor mistakes..
我不能在这里写下所有错误，所以只需将您的代码与我的代码进行比较，并理解您的错误.
I can't write all mistake here so just compare your code with mine code and understood your mistakes.
在这里您必须传递两个输入参数
Here you have to pass two input paramater
<ClientCode>string</ClientCode>
<key>string</key>
但是你把所有的错误都传递给了我.
but you are passing everything wrong..
您的错误代码
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$@!#@M^#R");
fromProp2.setType(String.class);
request.addProperty(fromProp2);
您必须像这样通过
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
// simple object access protocol
request.addProperty("ClientCode", aa);
request.addProperty("key", "Om$@!#@M^#R");
GetReport.Class的工作代码
package com.example.clientnetpositionreport;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;
import android.widget.TextView;
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.fragment_item_detail);
textView1 = (TextView) findViewById(R.id.item_detail);
String title= getIntent().getExtras().getString("ClientCode");
System.out.println("Data is " + title);
startWebAccess(title);
}
public void startWebAccess(String a) {
final String aa = a;
thread = new Thread() {
public void run() {
try {
Log.d("Req value0R", "Starting...");
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
// simple object access protocol
request.addProperty("ClientCode", aa);
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);
}
}
};
}
这是正常的代码，但是我传递的 ClientCode 和 key
This is code is working but I am not getting response may be I am passing wrong value of ClientCode and key
