What is this value for authtokentype suppose to be for Facebook using
AccountManager.getAuthToken? My code below will present the screen
prompting the user to allow my application access to the users
facebook account. If the user denies my application access then the
next time they launch the application, it will ask again. If the user
allows access to the account, the screen is not shown again (the way I
would it expect it to function). Once the user allows access, whenever
I try to get the token, I get an AuthenticationException with message
- 'No Response From Authenticator'. Any help would be most
appreciated!
