/**
 * Prompts the user for the email address and password. Also prompts for "Use this account as
 * default" if this is the 2nd+ account being set up.
 *
 * If the domain is well-known, the account is configured fully and checked immediately
 * using AccountCheckSettingsFragment.  If this succeeds we proceed directly to AccountSetupOptions.
 *
 * If the domain is not known, or the user selects Manual setup, we invoke the
 * AccountSetupAccountType activity where the user can begin to manually configure the account.
 *
 * === Support for automated testing ==
 * This activity can also be launched directly via ACTION_CREATE_ACCOUNT.  This is intended
 * only for use by continuous test systems, and is currently only available when
 * {@link ActivityManager#isRunningInTestHarness()} is set.  To use this mode, you must construct
 * an intent which contains all necessary information to create the account.  No connection
 * checking is done, so the account may or may not actually work.  Here is a sample command, for a
 * gmail account "test_account" with a password of "test_password".
 *
 *      $ adb shell am start -a com.android.email.CREATE_ACCOUNT \
 *          -e EMAIL test_account@gmail.com \
 *          -e USER "Test Account Name" \

 *          -e OUTGOING smtp+ssl+://test_account:test_password@smtp.gmail.com
 *
 * Note: For accounts that require the full email address in the login, encode the @ as %40.
 * Note: Exchange accounts that require device security policies cannot be created automatically.
