     * Direct access for forcing account creation
     * For use by continuous automated test system (e.g. in conjunction with monkey tests)
     *
     * === Support for automated testing ==
     * This activity can also be launched directly via INTENT_FORCE_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.FORCE_CREATE_ACCOUNT \
     *          -e EMAIL test_account@gmail.com \
     *          -e USER "Test Account Name" \
     *          -e INCOMING imap+ssl+://test_account:test_password@imap.gmail.com \
     *          -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.
     *
     * For accounts that correspond to services in providers.xml you can also use the following form
     *
     *      $adb shell am start -a com.android.email.FORCE_CREATE_ACCOUNT \
     *          -e EMAIL test_account@gmail.com \
     *          -e PASSWORD test_password
     *
     * and the appropriate incoming/outgoing information will be filled in automatically.
