What is the process behind the upgrade of the app in Android, is it just a replacement for APK or something else

Is this just the replacement of the new APK file (such as resetting it) or has it been updated?
What happens to the database tables associated with the older version?
What happens to the shared priorities associated with the older version?
Can anyone tell us a proper way to emulate this operation before launching it in the market?
1. Yes, the application has been replaced with the new one.
2. The database will be upgraded, so your SQLiteOpenHelper method of method will be called, so you have to process data with care, for example You do not want to delete the entire database and table, and just upgrade some special tables that have changed.
3. Shardya Reference will not be deleted, they will be kept. To simulate this, you can simply add an older version of your app to your device, and then install a new one. It will actually update your code as a Play Store , and as Eclipse does when you install an app again, which is your device / emulator But it is fully established.

App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,
