来自安卓系统的网络服务呼叫称权限被拒绝

Question

我在.net中有一个web服务，我在localhost中从android调用它。这是为了在模拟器显示中显示一个字符串，但它不起作用。它在模拟器中显示拒绝访问。

SoapTestActivity.java

package com.sample;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import org.ksoap2.*;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.*;

public class SoapTestActivity extends Activity {
    TextView result;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        result = (TextView)findViewById(R.id.result);
        final String NAMESPACE = "http://sample.com/";
        final String METHOD_NAME = "SayHello";    
        final String SOAP_ACTION = "http://sample.com/SayHello";
        final String URL = "http://192.168.1.108/WebService1/Service1.asmx";
        try {
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);            
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.setOutputSoapObject(request);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
            String resultValue = response.toString();
            result.setText(resultValue);           
        }
        catch (Exception e) {
            result.setText(e.getMessage());
        }
    }
}

manifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    android:versionCode="1"
    android:versionName="1.0" >

请将url 192.168.1.108更改为10.0.22:80

更改后，您将在Emulator 上获取数据

请参考http://developer.android.com/tools/devices/emulator.html#networkaddresses以供更多参考。
