Discussion: auth redirect URI for android

I was considering adding the ability to watch skill learning to my android app.  To do that I'd need to be able to "log in" and I'd need a key or something.

I'm still fuzzy on the oauth, but when I was looking at the form for registering a key I noticed an "Auth Redirect URI:" field.  I guess that's where glitch sends the token once the user has authorized the android app to access the APIs.  However, on an android device, you can't know the URI until the app is running.  It could have any IP address the cell network assigns it.  (and I hope it isn't doomed by the cell company's NAT).

Am I misinterpreting things?  Is this a known problem with mobile apps -vs- the Glitch API?
You dont actually need to have a return url thats callable like you think. Look into the android sdk
Ahah, that's speeding things up drastically.  I managed to make a successful query earlier.  Now I've stubbed it out so i can get the app behavior right without pounding the servers needlessly.
