Answer 1

For me the only thing that worked was to provide 2 oauth client ids. a web application client id AND an android client id

In my android app i use the client id and client secret of the web application. Even though i don't use the android client id anywhere in my app it is still required. ie if i delete the oauth android client in the google api console my app stops working EVEN THOUGH i dont use that client id ANYWHERE in my app.

this makes absolutely no sense to me! go figure . but so far this is the only thing that has worked.

un-freaking-believable.
