Kindle Fire and File Uploads

Question

I've tried everything I can think of to get the Kindle Fire Browser to accept uploads, no dice. The file picker shows up, but the upload errors. Every once in a blue moon it works, and I can't figure out why. I've tried both HTML5 and normal FORM POST uploads.

Anybody have ideas, or better luck?

Also, the file selector pretends to be HTML5, but then returns 0 for the file size, screwing up any file size display.

Haha. I write an upload component (krystalware.com/slickupload), so I like getting on the ball to make sure it works on as many browsers and devices as possible. Usually it's easy to suss out the issue and support a device (or determine that the device doesn't support uploads period), but in this case I'm stumped. – Feisty

Does it work if you turn off the silk cloud-acceleration feature? – Taxidermy

@Taxidermy - Yup, that seems to be exactly it -- uploads don't work with cloud acceleration on. As soon as I flip it off, uploads start working. Do you know of any way to detect cloud acceleration from the browser? – Feisty

Sorry, I don't. I haven't had a chance to do anything with a Fire, and it's been quite some time since I did web programming anyway. – Taxidermy

You could check whether the browser is on a kindle and display a warning along the lines of "uploads don't work with the silk feature on." Come to think of it, maybe the UA string says whether it's on? – Taxidermy

Answer 1

looks like in Silk 2.1 (current version in the FireHD) it now works as expected... i was able to upload test content with the accelerated page loading functions on and off

Answer 2

As long as Jquery Mobile Works Fine With Kindle fire Browser

Check uploadify plugin which can work on Jquery Mobile

http://www.uploadify.com/

Also Check this Tips and Tutorial

EDIT Checkout this

http://jquerymobile.com/demos/1.0a3/#docs/forms/index.html

And make sure

$.mobile.ajaxFormsEnabled = false;

And form attribute

<form id="form" action="/mobile/upload" method="post" enctype="multipart/form-data" data-ajax="false">

Uploadify uses flash. I need a raw browser based upload. Flash works for now on Android, but since Adobe has discontinued mobile development of Flash we can't rely on that. – Feisty

@Chris Hynes Could u check out valums.com/ajax-upload in your kindle fire browser – Orton

Still not working. Valums code breaks because the Kindle browser returns file size = 0 for all files, whether or not they have any data. – Feisty
