Doesn't write image

Hi all,

With the code below, no error is shown but no image is recorded on the selected file on application "barcode.png" .

Can anyone help me?

I'm using :

Samsung GT-I8530 OSX 10.9.4 Android SDK 20 Titanium 3.3.0 GA

    var win;
    function fireUpTheCamera() {
        var imageView; 
        Titanium.Media.showCamera({

            success:function(event)
            {
                var cropRect = event.cropRect;
    //          var image = event.media;
                event.media.nativePath = 'file:///mnt/sdcard/Pictures/CamKit/barcode.png';
                Ti.API.info('Our type was: '+event.mediaType);
                if(event.mediaType == Ti.Media.MEDIA_TYPE_PHOTO)
                {
                    imageView = Ti.UI.createImageView({
                        width:win.width,
                        height:win.height,
                        image:event.media
                    });
                    win.add(imageView);
                }
                else
                {
                    alert("got the wrong type back ="+event.mediaType);
                }
            },
            cancel:function()
            {
            },
            error:function(error)
            {
                // create alert
                var a = Ti.UI.createAlertDialog({
                    title:'Camera'
                });

                // set message
                if (error.code == Ti.Media.NO_CAMERA)
                {
                    a.setMessage('Please run this test on device');
                }
                else
                {
                    a.setMessage('Unexpected error: ' + error.code);
                }

                // show alert
                a.show();
            },
            saveToPhotoGallery:true,
            allowEditing:true,
            mediaTypes:[Ti.Media.MEDIA_TYPE_PHOTO]
        });
    }

    win = Ti.UI.createWindow({
    //  title:_args.title
    });
    if (Ti.Platform.osname === 'android') 
    {
        win.addEventListener('open', function(e) 
        {
            fireUpTheCamera();
        });
    } 
    else 
    {
        fireUpTheCamera();  
    }
    win.open();
