iOS Question DocumentPickerViewController, can't select a .db file

[marcick]

The question has been already posted here but the solution does not work for me.
I checked with "public.database", "public.data" and "public.contents" but the .db files are grayed not selectable

    Dim DocumentPicker As DocumentPickerViewController
    DocumentPicker.InitializeImport("picker", Array("public.content"))
    DocumentPicker.Show(pg, Sender)

Running on Iphone 6 IOS 12.5.6
Any hint ?

try public.data thats working for my db backups

Dim DocumentPicker As DocumentPickerViewController
DocumentPicker.InitializeImport("picker", Array("public.data"))
DocumentPicker.Show(B4XPages.GetNativeParent(Me), xsbtn_restore.mBase)
Wait For Picker_Complete (Success As Boolean, URLs As List)

Thank you but as I wrote, "I checked with "public.database", "public.data" and "public.contents" but the .db files are grayed not selectable"

try it togehter with:

Make your app files accessible with Files app

#PlistExtra: LSSupportsOpeningDocumentsInPlaceUIFileSharingEnabled All files in File.DirDocuments / XUI.DefaultFolder will be accessible from the Files app (and iTunes as well).

nothing, doesn't work ....
(anyway I don't want file.dirdocument be accessible from file app)

I can see and select other files (as text or csv) but not the.db

The identifier for this type is public.database.

My solution works!
Look in the example project.
IOS 16.2

i see, you are using an very old version of ios...

It is a version with a current security update. But from version 12-16 has done a lot to IOS, I think that is the error.

Yes, that is the problem ... tested now on another Iphone12 and works fine as you say.
I'm using this Iphone6 for developing and it's a good device, I don't want to limit my app excluding IOS12.
The latest IOS version available for this device is 12.5.6

So, what to do ?
Maybe I can change the file extension creating a custom identifier ?
Thanks
