Screenshot is not sending to email in titanium

Question

i've used the code below it was the accepted answer that was given at http://developer.appcelerator.com/question/135462/save-screenshot-temporarily-then-retrieve-when-ready

But when the email dialog box opens it shows a attached file which was screenshot but after sending email there is no attachment in received email.it means screenshot is not sending.

can anyone tell what's wrong in this code???

var win = Ti.UI.createWindow({
    // backgroundColor : '#666666'
    backgroundColor : 'red',
    // backgroundImage : 'img/1.jpg'
});

var btn = Ti.UI.createButton({
    width : 100,
    height : 30,
    title : 'Test'
});

btn.addEventListener('click', function(e) {
    Titanium.Media.takeScreenshot(function(e) {
        var f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'test.png');
        f.write(e.media);

        var emailDialog = Titanium.UI.createEmailDialog();
        emailDialog.setToRecipients(['test@gmail.com']);
        emailDialog.setSubject('test');
        emailDialog.setMessageBody('testing......');
        emailDialog.setHtml(true);
        emailDialog.setBarColor('black');
        emailDialog.addAttachment(f.read());

        emailDialog.addEventListener('complete', function(e) {
            if(e.result == emailDialog.SENT) {

                alert("message was sent");

            }
        });
        emailDialog.open();
    });
});

win.add(btn);

win.open();

The addAttachment function can take a blob, you don't have to save it to disk. Also, this may not be working because you may not have write access to the applicationDataDirectory .

Instead just pass the supplied blob from e.media like this:

Titanium.Media.takeScreenshot(function(e) {
    var emailDialog = Titanium.UI.createEmailDialog();
    // Get the supplied blob and attach
    emailDialog.addAttachment(e.media);
    // ...... add other email things here
});
