Android AccountManager authToken and OAuth

Question

My task is to write IMAP e-mail client for Gmail. So far I know client should authenticate through OAuth (there's also a java library for IMAP auth by Google). But I'd like to set user free from any password typing.

Android provides a cool 'native' way to gain authToken for google account services via AccountManager. But I wonder how to use authToken and what is it for? Is it only for GAE authentication?

Is there any way to get oauthToken and oauthTokenSecret without browser (via AccountManager)?

Answer 1

Have you tried using "oauth2:https://mail.google.com/" as the "auth token type" (authTokenType parameter) when calling AccountManager.getAutToken() ?

According what is said at 46:50 in the talk you mentioned, it should work.

By the way, this page describes how to get an OAuth2 token for Google Tasks, and it has a link to a code sample. It also makes it sounds like it is just a matter of providing the right authTokenType parameter.
