傳輸.apk文件我已經轉換我的apk文件成字節陣列,並使用web服務如下需要使用web服務

[WebMethod] 
    public byte[] GetApkFile(string deviceID) 
    { 
     try 
     { 
      string path = ServiceHelper.GetTempFilePath(); 
      string fileName = path + "\\VersionUpdate.apk"; 
      FileStream fileStream = File.OpenRead(fileName); 
      return ConvertStreamToByteBuffer(fileStream);   
     } 
     catch (Exception ex) 
     { 
      throw ex; 

     } 

    } 

     public byte[] ConvertStreamToByteBuffer(System.IO.Stream theStream) 
    { 
     int b1; 
     System.IO.MemoryStream tempStream = new System.IO.MemoryStream(); 
     while ((b1 = theStream.ReadByte()) != -1) 
     { 
      tempStream.WriteByte(((byte)b1)); 
     } 
     return tempStream.ToArray(); 
    } 

我在我的機器人應用消耗使用KSOAP協議網絡服務爲字節發送陣列如下給出

public void DownloadApkFile(String serverIPAddress, 
     String deviceId) { 

    String SOAP_ACTION = "http://VisionEPODWebService/GetApkFile"; 
    String OPERATION_NAME = "GetApkFile"; 
    String WSDL_TARGET_NAMESPACE = "http://VisionEPODWebService/"; 
    String SOAP_ADDRESS = ""; 
    SOAP_ADDRESS = "http://" + serverIPAddress 
      + "/VisionEPODWebService/SystemData.asmx"; 
    SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE, 
      OPERATION_NAME); 
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
      SoapEnvelope.VER10); 
    new MarshalBase64().register(envelope); 
    envelope.encodingStyle = SoapEnvelope.ENC; 
    request.addProperty("deviceID", deviceId); 
    envelope.dotNet = true; 
    envelope.setOutputSoapObject(request); 
    HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS); 
    try { 
     httpTransport.call(SOAP_ACTION, envelope); 
     Object response = envelope.getResponse(); 
     byte[] b=response.toString().getBytes(); 

     String fileName = "/sdcard/" + "VersionUpdate" + ".apk"; 

     FileOutputStream fileOuputStream = 
        new FileOutputStream(fileName); 
     fileOuputStream.write(b); 
     fileOuputStream.close();   

    } 

    catch (Exception exception) { 
     exception.toString();   
    } 

問題是,我沒有得到確切的apk文件後,將字節數組[]返回到文件。

請問任何人請查看代碼,請告訴我有沒有在這個錯誤。

我需要將轉換後的byte [] apk文件轉換回SD卡中的.apk文件進行安裝。

response.toString()很可能不是您的APK的字符串表示。

嘗試以下操作:

SoapObject result = (SoapObject)envelope.bodyIn; 
byte[] b=result.toString().getBytes(); 
+0

我已經嘗試過了......但問題是,我現在用點網webservice.So的時候纔來的Java部分不能解析到回APK轉換文件文件。如果它是Java到Java通信,它將是可能的。 –
