Changing Google account settings on an HTC Hero

When I created DrHotdog.net I wanted to switch my HTC Hero from auto-syncing my mail, contacts and calendar data with my GMail.com account to my new DrHotdog.net account.  It isn't obvious how to do this, and if you search forums for a solution the most common suggestion is to do a full wipe/factory reset and set up the phone again from scratch.  Fortunately there is a less drastic way to do this, which I'll describe here.

First go to Settings > Applications > Manage applications, and tap the Google Apps entry.  Then tap 'Clear data', and tap 'OK' to confirm.  This will delete your existing Google account details.  To enter your new account details go to Settings > Data synchronization > Google and you'll be prompted with the set up dialogue.  Enter your new account details and you're done.

What this won't do for you is move all your mail, contacts and calendar data from the old account to the new one, so in order for all your data to appear on your phone as it did before you'll first need to transfer it between the two accounts.  I'll describe how I did that in my next post.

If you do use a Google Apps account on your Hero (or other Android phone, presumably) you'll still need to use your GMail.com account to buy paid apps from the Android Marketplace as Google Checkout accounts can only be associated with GMail.com accounts.  This isn't a problem though, the first time you try to buy a paid app in the Marketplace you'll be prompted by the details of the GMail.com account to use for Google Checkout and it'll work as normal from then on.

Update 17 Feb 2010:

I glad that this method worked for most of the people who've left comments.  For those that had problems, I can't unfortunately offer much in the way of explanation as I didn't get any errors myself so can't investigate what went wrong.  The only possible issue that I can think of is that if you don't have IMAP enabled for your Google Apps Mail account then that would prevent the GMail app on the phone from syncing your email, so check your settings if mail sync is a problem.  

In any case the worst case scenario here is that you end up having to do the full wipe/factory reset that you would've had to do anyway if you didn't use my method.  You may as well try it as described above, if it works then fine, if not then make sure you've backed up any important user data then wipe.  There's no great risk to giving it a try, remember that clearing the Google Apps data on the phone as I describe doesn't permanently delete any of your Google emails, contacts or calendar data, it just deletes the local copies on the phone.  The master copies will still be safely stored in the Google 'cloud', ready to be retrieved at any time.
