// Android implementation of UserAuthorizer, using the single 'nouser' SbUser to
// represent the Android platform running our app.  Unlike game consoles which
// launch the app as a particular platform user, Android always launches the app
// as the same platform "user" no matter what accounts may be on the device.

// Signing-in is a higher-level concept that is implemented by the Android app
// using the Android AccountManager and/or Google Play Services to select an
// account and get auth tokens for the selected account to make "signed-in"
// requests.  Account selection is accomplished by prompting the user as needed
// when getting a token with AuthorizeUser(), and remembering the selected
// account to be used without prompting in RefreshAuthorization().
