Android Question detecting first launch of updated app?

[Dave O]

Hi all,

When I update my app with new features (e.g. change the versionCode), I'd like to auto-show a "what's new" dialog, so the user can see what's changed.

Does Android (or B4A) have any way of detecting the first launch of an updated app, or do I need to store my own flag somewhere and do the checking in Activity_Create?

Just wondering if I need to roll my own code or if there's a standard way of doing this?

Thanks!

You need to create your own flag.

Something like (pseudocode):

If Version_Written_To_File <> CurrentVersion
  DoVersionUpdateStuff()
  WriteCurrentVersionToFile()
End If
