I'm also a newbie so might be mistaken as to your scenario, but I had a similar experience... I was trying to mine scrypt based coins using a sha256 setup when i first started - it looked liked guiminer was doing the work, but nothing was showing on the pool dashboard.
Could that be the problem?
I'm not sure, since only I can only connect to the one server and one port because of getwork protocol. And it's a registered Kindle so I can't modify anything on the tablet.
It appears looking at multipools site, that the Http address I'm using does both sha256 and scrypt depending on the miner connected, does anyone use multipool that can shed some light on this?
Also should I possibly direct my tablet to my computer(which is "digging" with the qt client) instead of their server? I was looking at mining proxys but I'm way too new to understand all the programing required.
Multipool doesn't give the workers a password.
EDIT-
Going through the logs, I'm seing a "submit_upstream_work_ json_rpc_call failed" and then it goes back to threads and yays
This is my exact info:

1 thread
ARM(default)
I fill in the blanks for the url and workername/password. Threads was at 1 when i first started the app, and CPU architecture is a drop-down box offering default and NEON. Then I click start.
