Convertir un flux binaire en octet?

Question

J'ai un flux binaire et je veux convertir en octets. après cela, je veux le télécharger sur la carte SD.

Mes services web:

POST /**********Mobile/**********.asmx HTTP/1.1 
    Host: ***.***.*.*

    <soap:Body>

    <GetDocumentResponse xmlns="http://tempuri.org/"> 
    <GetDocumentResult>string</GetDocumentResult> 
    </GetDocumentResponse> 
</soap:Body> 
</soap:Envelope> 

Ce que je suis en train est

SoapObject DocumentRequest = new SoapObject(NAMESPACE, GET_DOCUMENT_METHOD); 

     DocumentRequest.addProperty("DocumentID", ID); 
     Log.i("DocumentID", ID); 

     SoapSerializationEnvelope Envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
     Envelope.dotNet = true; 
     Envelope.setOutputSoapObject(DocumentRequest); 
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
     androidHttpTransport.debug = true; 

     androidHttpTransport.call(SOAP_ACTION_GETDOCUMENT, Envelope); 

     SoapPrimitive DocumentResponse = (SoapPrimitive)Envelope.getResponse(); 
     Log.i("DocumentResponse", DocumentResponse.toString()); 

     String DocAsString = DocumentResponse.toString(); 

     byte[] decodedString = DocAsString.getBytes(); 

     Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 
     ImageView DisplayDoc= (ImageView)findViewById(R.id.displayimage); 
     DisplayDoc.setImageBitmap(decodedByte); 
} 

Je reçois flux binaire sous forme de chaîne est-il juste ou je dois utiliser base64Binary. Si oui, veuillez me faire savoir quelle est la bonne approche pour télécharger l'image/.pdf/word doc. J'ai traversé avec des recherches de diff mais pas utile. grâce

EDIT:

SoapPrimitive DocumentResponse = (SoapPrimitive)Envelope.getResponse(); 
     Log.i("DocumentResponse", DocumentResponse.toString()); 

     String DocAsString = DocumentResponse.toString(); 

     byte[] decodedString = Base64.decode(DocAsString, Base64.DEFAULT); 

     /*Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 
     ImageView DisplayDoc= (ImageView)findViewById(R.id.displayimage); 
     DisplayDoc.setImageBitmap(decodedByte);*/ 

     File direct = new File(Environment.getExternalStorageDirectory() + "/Downloads"); 

     if(!direct.exists()) { 
      direct.mkdir(); } 
     File photo=new File(Environment.getExternalStorageDirectory() + "/Downloads", ID); 

     if (photo.exists()) { 
       photo.delete(); } 

    try { 
     FileOutputStream fos=new FileOutputStream(photo.getPath()); 

     fos.write(decodedString); 
     fos.close(); 

     ContentValues values= new ContentValues(); 

     System.out.println(values); 

    } 
    catch (java.io.IOException e) 
    { 
     Log.e("PictureDemo", "Exception in photoCallback", e); 
    } 
    } 
    catch(Exception e) { 
     e.printStackTrace(); 
     Toast.makeText(getApplicationContext(), " Network Exception : " + e 
       + "Please check network connectivity.", Toast.LENGTH_LONG).show(); 
    }

Answer 1

    try { 
        ht.call(SOAP_ACTION, envelope); 

        final SoapPrimitive response = (SoapPrimitive) envelope.getResponse(); 
        String str =DocumentResponse.toString(); 

         byte[] decodedString = Base64.decode(str, Base64.DEFAULT); 

        File direct = new File(Environment.getExternalStorageDirectory() + "/Foldername"); 

         if(!direct.exists()) 
         { 
          direct.mkdir(); 
         } 

        File photo=new File(Environment.getExternalStorageDirectory() + "/Foldername",Filename); 


        if (photo.exists()) 
        { 
         photo.delete(); 
        } 

        try { 
        FileOutputStream fos=new FileOutputStream(photo.getPath()); 

        fos.write(decodedString); 
        fos.close(); 

        ContentValues values= new ContentValues(); 

        } 
        catch (java.io.IOException e) 
        { 
        Log.e("PictureDemo", "Exception in photoCallback", e); 
        } 
       } 


       catch (Exception e) { 
       e.printStackTrace(); 
      } 

Convertir votre chaîne Decode base64.

Exemple: byte [] decodedString = Base64.decode (str, Base64.DEFAULT);

Utilisez cet octet pour enregistrer le fichier dans la carte SD.

Exemple: fos.write (décodedString);
