Android Question Google Play APK update installation issue

[Taha]

I found that if new version of APK was updated through Google Play some (I am not sure) additional files (in Files folder) were not overwritten. That leads to application mistakes for example if new table added into database file.

Is it possible to force files replacement or clean installation (uninstall previous version and then install new)?

The assets files will be replaced. Other files will not be replaced.

 Sub Process_Globals
DimDBFileNameAsString : DBFileName = "MyDB.db"
DimDBFileDirAsString : DBFileDir = File.DirInternal
End Sub
...
If File.Exists(DBFileDir, DBFileName) = False  Then
            File.Copy(File.DirAssets, DBFileName, DBFileDir, DBFileName)
            SQL1.Initialize(DBFileDir, DBFileName, False)
        Else
            SQL1.Initialize(DBFileDir, DBFileName, False)
        End If
...

This is strange from the code - the file is supposed to be copied from Assets folder.

Your code is copying the database ONLY if it doesn't exist on the device, if you update the app, the DB already exists and it won't be overwritten.

Ooooh, yes, you are right! Many thanks, NJDude!
