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());



    }



}
