I tested from my Android smartphone (HTC Inspire 4G) and was unable to upload as well. I would get so far as to select and image to upload but it wouldn't upload. Is this similar to what you were experiencing?
I've went ahead and reported the issue to our developers. Thank you for posting about the issue here on the forums.
No, actually, I started to try to upload through the web page but gave up when I had trouble logging in. The first problem is that the login page doesn’t display well on the mobile version of Google Chrome. The transparency doesn’t work properly. Next, I have a rather long email address associated with my Adobe account. The address includes a hyphen which means I have to switch to an alternate screen and then back. That’s a lot of typing. And, I have a secure password that is impossible to remember. On my PC I have ways of dealing with that. Not so, on my mobile devices. Finally, I’ve been clicking the “Remember me” checkbox when logging into Adobe websites for years. It has never worked. So, the first time I tried logging in via the website from my phone it became clear to me that this would never be an acceptable workflow from a mobile device.
Right now, as far as I can see, the best workaround would be to email a photo to myself and then download the photo on my tablet. Clearly, this is a hassle and the more photos I want to edit with Photoshop Touch the more of a hassle it becomes. For one thing it eats up my mobile bandwidth. But mainly, it’s just too cumbersome.
For the Creative Cloud to work in a mobile scenario the whole process has to be convenient & easy. I think there needs to be a CC app which can remember login info and automatically upload photos from a phone to the CC. See my comments above at how seamlessly it works in Google+.
