アンドロイドとウェブサービスの接続に失敗する

Question

こんにちは、アンドロイドからウェブサービスへの接続を試しています。これを行うためには、私が行っている手順は、次のとおりです。

は

1. は、無料のWebサービスを見つける：http://services.aonaware.com/DictService/DictService.asmx

2. Androidのメーカーに

3. 変更権限を持っているためにマニフェストファイルを、基本的なアクティビティを作成次の行を追加することにより、インターネットを使用する：

   は、Androidの許可使用します。name = "android.permission.INTERNETあなた"

4. は、次のコードを使用してWebサービスを利用するためにksoap2ライブラリに

5. てみてくださいを追加します。

   @Override 
   protected void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
       setContentView(R.layout.activity_main); 
   
       tv = (TextView) findViewById(R.id.textView1); 
   
       SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
       PropertyInfo property = new PropertyInfo(); 
       property.setName("word"); 
       //property.setType(String.class); 
       property.setValue("computer"); 
       request.addProperty(property); 
   
   
       SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
       envelope.setOutputSoapObject(request); 
   
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
       Object response = null; 
       try { 
        androidHttpTransport.getServiceConnection(); 
   
        try { 
         androidHttpTransport.call(SOAP_ACTION, envelope); 
        } catch (IOException e) { 
         e.printStackTrace(); 
        } catch (XmlPullParserException e) { 
         e.printStackTrace(); 
        } 
        tv.setText("success"); 
        response = envelope.getResponse(); 
        response.toString(); 
        String resultData= response.toString(); 
        tv.setText(resultData); 
   
       } catch (Exception e) { 
        e.printStackTrace(); 
       } 
   } 
   

declarationsしかし、textView1が結果を取得されていません。私のコードに何か問題はありますか？

注：私はGradleのバージョンここでは2.10

Webサービスを実行するためにAsyncTaskを使用してみてください。ここにサンプルがあります - >android.os.NetworkOnMainThreadException for webservice (ksoap)

import org.ksoap2.SoapEnvelope; 
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.AsyncTask; 
import android.os.Bundle; 
import android.util.Log; 

public class MainActivity extends Activity { 
    private String TAG ="Vik"; 

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

     AsyncCallWS task = new AsyncCallWS(); 
     task.execute(); 
    } 

    private class AsyncCallWS extends AsyncTask<Void, Void, Void> { 
     @Override 
     protected Void doInBackground(Void... params) { 
      Log.i(TAG, "doInBackground"); 
      calculate(); 
      return null; 
     } 

     @Override 
     protected void onPostExecute(Void result) { 
      Log.i(TAG, "onPostExecute"); 
     } 

     @Override 
     protected void onPreExecute() { 
      Log.i(TAG, "onPreExecute"); 
     } 

     @Override 
     protected void onProgressUpdate(Void... values) { 
      Log.i(TAG, "onProgressUpdate"); 
     } 

    } 

    public void calculate() 
    { 
     String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit"; 
     String METHOD_NAME = "CelsiusToFahrenheit"; 
     String NAMESPACE = "http://tempuri.org/"; 
     String URL = "http://www.w3schools.com/webservices/tempconvert.asmx"; 

     try { 
      SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); 
      Request.addProperty("Celsius", "32"); 

      SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
      soapEnvelope.dotNet = true; 
      soapEnvelope.setOutputSoapObject(Request); 

      HttpTransportSE transport= new HttpTransportSE(URL); 

      transport.call(SOAP_ACTION, soapEnvelope); 
      SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse(); 

      Log.i(TAG, "Result Celsius: " + resultString); 
     } 
     catch(Exception ex) { 
      Log.e(TAG, "Error: " + ex.getMessage()); 
     } 

     SOAP_ACTION = "http://tempuri.org/FahrenheitToCelsius"; 
     METHOD_NAME = "FahrenheitToCelsius"; 
     try { 
      SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); 
      Request.addProperty("Fahrenheit", "100"); 

      SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
      soapEnvelope.dotNet = true; 
      soapEnvelope.setOutputSoapObject(Request); 

      HttpTransportSE transport= new HttpTransportSE(URL); 

      transport.call(SOAP_ACTION, soapEnvelope); 
      SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse(); 

      Log.i(TAG, "Result Fahrenheit: " + resultString); 
     } 
     catch(Exception ex) { 
      Log.e(TAG, "Error: " + ex.getMessage()); 
     } 
    } 

}

でのAndroid Studioを使用 は、ASP.Net Webサービスのためのルーチンです：

SOAPオブジェクトを読む

public static SoapPrimitive callProcServiceForObject(String serviceMethod, String storedProc, String params) throws Exception { 
    String NAMESPACE = "http://YourWebServiceURL.com"; 
    String METHOD_NAME = getMethodName(serviceMethod); 
    String SOAP_ACTION = NAMESPACE + METHOD_NAME; 
    String URL = "http://YourWebServiceURL.com"; 
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    request.addProperty("sPassword", YourPassword); 
    request.addProperty("sData", GlobalVars.serverDB); 
    request.addProperty("sSP_Name", storedProc); 
    request.addProperty("sParam", params); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

    // Enable the below property if consuming .Net service 
    envelope.dotNet = true; 
    envelope.setOutputSoapObject(request); 
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL, timeout); 

    SoapObject returnable = null; 
    try { 
     androidHttpTransport.call(SOAP_ACTION, envelope); 
     returnable = (SoapObject)envelope.getResponse(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
     throw new Exception("Msg:" + e.getMessage() + "; SP:" + storedProc + "; Params: " + params + "; Method:" + METHOD_NAME); 
    } 
    return returnable; 
} 

：

SoapPrimitive response = callProcServiceForObject(storedProcedureName, params); 
if (response != null) { 
    String sResponse = response.toString(); 
}
