I want to get file in rest service from android. In my code i send filestream from android via url. If i use like this My entire app is not working by saying...

Logcat

Operation Fileacces in contract 'IREST' has a query variable named
stream of type System.IO.FileStream, but type
System.IO.FileStream is not convertible by QueryStringConverter.
 Variables for UriTemplate query values must have types that can
be converted by QueryStringConverter

Here I have post my coding FYR

 public void onActivityResult(int requestCode, int resultCode, Intent data) 
 super.onActivityResult(requestCode, resultCode, data);
 if (requestCode == FILE_PICKER_REQUEST_CODE && resultCode == Activity.RESULT_OK) 
 Uri content_describer = data.getData();

 String src = null;
 try 
 src = getFilePath(UploadActivity.this, content_describer);
 catch (URISyntaxException e) 
 e.printStackTrace();
 
 Log.d("src is: ", src);
 source = new File(src);
 fname = source.getName();

 Button text = (Button) findViewById(R.id.txt);
 text.setText(fname);


 text.setOnClickListener(new View.OnClickListener() 
 @Override
 public void onClick(View view) 
 try 
 FileOpen.openFile(UploadActivity.this, source);
 catch (IOException e) 
 e.printStackTrace();
 
 
 );


 
 

Onclick event in action bar icon:

 @Override
 public boolean onOptionsItemSelected(MenuItem item) 
int id = item.getItemId();

 //noinspection SimplifiableIfStatement
 if (id == R.id.mybutton) 
 new Save().execute();
 return true;
 

 return super.onOptionsItemSelected(item);
 

SAVE function asynctask

private class Save extends AsyncTask<String,Void,String> 

 protected void onPreExecute() 
 super.onPreExecute();
 

 @Override
 protected String doInBackground(String... params) 
 try 
 fis=new FileInputStream(source);
 catch (FileNotFoundException e) 
 e.printStackTrace();
 

 ServiceHandler jsonParser = new ServiceHandler();
 String fileaccess = ip+"Mobile/rest.svc/Fileacces?stream="+fis+"&filename="+fname;
 Log.d("Fileaccess","fileaccess"+fileaccess);
 String result = jsonParser.makeServiceCall(fileaccess, ServiceHandler.GET);
 Log.i("fileaccess", "result: > " + result);
 return null;
 


 @Override
 protected void onPostExecute(String s) 
 super.onPostExecute(s);
 System.out.println(s);

 

 

My rest function in vb.net

 Public Function fileacces(ByVal stream As FileStream, ByVal filename As String) As String Implements IREST.fileacces
 Dim result = ""

 Try

 Dim path = "D:XXXYYYECM SourceArchiveEZECMSettingsMonitor" + filename
 Dim fileStream = New FileStream(path, FileMode.Create, FileAccess.Write)
 stream.CopyTo(fileStream)
 fileStream.Dispose()
 result = "file uploaded"


 Catch ex As Exception

 End Try
 Return result
 End Function

kindly use base 64

like this

public void uploadFile(final String selectedFilePath) 
 try 


 FileInputStream inputStream = new FileInputStream(selectedFilePath);
 byte byteArray = IOUtils.toByteArray(inputStream);

 final String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
 getActivity().runOnUiThread(new Runnable() 
 @Override
 public void run() 
 // tvFileName.setText(encoded);
 Log.e("File Base 64",encoded);
 filebas64=encoded;
 
 );


 catch (FileNotFoundException e) 
 e.printStackTrace();
 Log.e("Error",e.toString());

 catch (IOException e) 
 e.printStackTrace();
 Log.e("Error",e.toString());
