I installed the Stack Exchange Android app, but I cannot login with my Stack Overflow account (it is not recognized as a Stack Exchange account). How can I make/upgrade my Stack OVerflow login/account so I can use the Android app?
Note 1: I don't have a separate Stack Exchange account, but from the app description the app should grant access to any of the Stack Exchange sub-sites, only that it doesn't without opening a global account.
Note 2: Another option which I am not sure of, that I read in other posts here, is to go ahead and open the Stack Exchange account with the same OpenID I use for Stack Overflow and the system will recognize the similarity and merge the accounts into one. I need confirmation if this is indeed the way to go.
