40/**
41 * Entry point Actiivty for account setup. Works as follows
42 * 0) If it is a multi-user system with multiple users, it shows a warning dialog first.
43 *    If the user accepts this warning, it moves on to step 1.
44 * 1) When the other Activities launch this Activity, it launches {@link ChooseAccountActivity}
45 *    without showing anything.
46 * 2) After receiving an account type from ChooseAccountActivity, this Activity launches the
47 *    account setup specified by AccountManager.
48 * 3) After the account setup, this Activity finishes without showing anything.
49 *
50 * Note:
51 * Previously this Activity did what {@link ChooseAccountActivity} does right now, but we
52 * currently delegate the work to the other Activity. When we let this Activity do that work, users
53 * would see the list of account types when leaving this Activity, since the UI is already ready
54 * when returning from each account setup, which doesn't look good.
