UIThreadException when saving doc for first time

[GoogleCodeExporter]

Not sure how to reproduce. Produced it twice trying to save a doc with the 
same name as an existing doc. Existing doc wasn't appearing in doc browser, 
but was appearing in Google Docs. Am using a Google Apps account (GAFYD). 
Am curious to know how it connected to my Google Apps account when I have a 
normal Google account with the same email address and password. Probably 
unrelated.

Thanks for finding and posting this bug!

This might be related to gdata-issue:
http://code.google.com/p/gdata-issues/issues/detail?id=1520

I'll add some error handling and probably force users to always create 
documents with
unique names that aren't already created.

Made some changes to try to address this problem also. You can get them by re-
downloading Nocs 2.1, and re-installing it.

The Apps account/Gmail account issue is weird indeed, and some people have been 
having 
sort of similar GData server issues lately. I wonder if it's something to do 
with which 
account you were last signed in.

Quick turnaround, nice work! Regarding Apps acc/Google acc, you can have active 
sessions for *both* services at the same time. Nocs has only ever connected to 
my Apps 
acc but I do use it more than my non-apps Google acc namesake. Perhaps worth 
another 
issue.

Found out that by default, the GData client libraries set the accountType 
parameter
to HOSTED_OR_GOOGLE. That means Google's ClientLogin will first try to 
authenticate
as a Google Apps hosted account and then as a Google Account. This becomes 
tricky if
user@example.com is both a Google Account and a Google Apps account, like in 
your case.

I'll look into this and add an option for the Login screen to explicitly set the
accountType to avoid this problem.
