Re: [android-developers] Releasing Updates To My App - Is It Patching Or Replacing?

If I publish an update to my app on the Android Market, will the app only "patch" (or only update changes to current application) or will it just replace the old application with the updated one?

It's replaced, AFAIK. I don't see any reason to "patch" it.
 
The reason is because for my app I need the user to retain some information (such as a database) on their phone that is gathered from the user on the app's first setup and not have to ask the user to repopulate this data on every update.

User's local data is preserved with each update. Android would not be very poppular if every single app lost its user's data on each update.
