Android- Upload photo to the server

*The UploadProduct.class register a product in my database and upload the photo to my server. I am trying to upload a file to my server. When I execute my app this work perfectly, the product is registered in the database but in my server , the photo had not been loaded.

When I debug , I put a breakpoint in httppost.setEntity(mpEntity); , the value of file atribute is /storage/emulated/0/Needyt/20150529_104715.jpg

The path where I save my files is http://ift.tt/1KCisaP and the path of upload.php is http://aaaa.com/app

Here my code:

atributes:

private List<NameValuePair> params = new ArrayList<NameValuePair>(1);
private File file;
private String imageFileName = "";
private String urlImag ="http://ift.tt/1KCisaP";
private EditText  etNombreProducto,etDescripcion,etPrecioDia,etPrecioSemana;
private Bitmap bitmap=null;

methods:

public void takePhoto() {



        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        imageFileName = timeStamp  + ".jpg";


        //Creamos el Intent para llamar a la Camara
        Intent cameraIntent = new Intent(
                android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        //Creamos una carpeta en la memeria del terminal
        File imagesFolder = new File(
                Environment.getExternalStorageDirectory(), "Needyt");
        imagesFolder.mkdirs();
        //anadimos el nombre de la imagen
        file= new File(imagesFolder, imageFileName);
        Uri uriSavedImage = Uri.fromFile(file);
        //Le decimos al Intent que queremos grabar la imagen
        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
        //Lanzamos la aplicacion de la camara con retorno (forResult)
        startActivityForResult(cameraIntent, 1);


    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        //Comprovamos que la foto se a realizado
        if (requestCode == 1 && resultCode == RESULT_OK) {
            //Creamos un bitmap con la imagen recientemente
            //almacenada en la memoria
            bitmap= BitmapFactory.decodeFile(
                    Environment.getExternalStorageDirectory() +
                            "/aaaa/" + imageFileName);
//            //Anadimos el bitmap al imageView para
//            //mostrarlo por pantalla
//            img.setImageBitmap(bMap);
        }
    }
