Android Question detecting first launch of updated app?

    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):

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