不在Android中使用KSOAP2加载数据

Question

我开发了一个使用KSOAP2 API下载数据的Android应用程序。它适用于Android 2.2，但它不适用于Android 4.0。这两个版本之间是否有任何配置或任何其他差异？

这是代码......`package nj.example;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class AandroidWebserviceActivity extends Activity {
/** Called when the activity is first created. */
private final String NAMESPACE=here`"http://www.naveenbalani.com/webservices/WassupAndroidService/";
private final String URL = "http://naveenbalani.com/WassupAndroid.asmx";       
private final String SOAP_ACTION = "http://www.naveenbalani.com/webservices/WassupAndroidService/todaysMessage";
private final String METHOD_NAME = "todaysMessage";
@Override
public void onCreate(Bundle savedInstanceState) {    
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
   //Create Soap Object
    SoapObject object=new SoapObject(NAMESPACE,METHOD_NAME);
 SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet=true;
    envelope.setOutputSoapObject(object);
   //  System.out.println("sset envelope"+envelope);
    HttpTransportSE androidtransportSE= new HttpTransportSE(URL);
    //System.out.println("after asign url");
     try
     {
         androidtransportSE.call(SOAP_ACTION,envelope);  //problem is here
         SoapPrimitive response=(SoapPrimitive)(envelope.getResponse());
         Log.i("Response", response.toString()); 
         TextView tv = new TextView(this);
         tv.setText(response.toString());         
         setContentView(tv);
     }
     catch(Exception e){}



}

}

Manifest.xml

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="nj.example"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
 <uses-permission android:name="android.permission.INTERNET"/>
<application 
  android:label="@string/app_name" >         
     <activity
        android:name=".AandroidWebserviceActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

提前致谢。
