从android应用程序调用asmx Web服务会引发异常：无法序列化

Question

在“我的应用程序”中，我想将图像上传到具有asmx Web服务的Web服务器。在该Web服务中，有两个参数，一个是文件名，另一个是字节数组中的文件。但是当我使用soap api调用它时，它会抛出

异常

  

java.lang.RuntimeException：无法序列化：[B @ 8357037

这是我的android代码，在意图服务类中调用以下方法。

public void uploadFile(String sourceFileUri,String fileName)
{
    try
    {
        File file = new File(imgPath);
        byte[] bytesArray = new byte[(int) file.length()];

        try
        {
            FileInputStream fis = null;
            fis = new FileInputStream(file);
            fis.read(bytesArray); //read file into bytes[]
         //   fis.close();
        }
        catch (FileNotFoundException e)
        {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);

        request.addProperty("f",bytesArray);
        request.addProperty("fileName",fileName.toString());

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;

        envelope.setOutputSoapObject(request);

        HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
        try
        {
            httpTransport.call(SOAP_ACTION, envelope);
            Object response = envelope.getResponse();
            Toast.makeText(getBaseContext(), response.toString(),Toast.LENGTH_LONG).show();

        }
        catch (Exception exception)
        {
            Toast.makeText(getBaseContext(), exception.toString(),Toast.LENGTH_LONG).show();
        }

如何调用asmx服务或如何解决上述异常？
