Did you see https://www.b4x.com/android/forum/threads/b4x-cloudkvs-synchronized-key-value-store.63536/#content

It should work with CloudKVS

i am not sure this is what i need.

both app are installed on my device.

i have just created a new App (like mytools1 and now i have mytools2)
now i want the user to be able to export all data from mytools1 to mytools2

the only problem is that in the first app i used a different approach to save all data so i created a codemodule and i am now creating a key value store db in the first app and now i would like to import all data from that db to the new app. (the new app is already working with key value store)

Maybe this thread can be of help to find out the path for the db from App A
https://www.b4x.com/android/forum/threads/build-path-to-app-b-from-app-a.81104/

Once you know the correct path you can open the DB and import the Data to another DB (KVS of App B)

as you can see i have no "File.not.found..." error so the path is correct.
i dont know why it crashes

actually the error happens here:

result = ser.ConvertBytesToObject(rs.GetBlob2(0))

this is the whole code of the sub

Public Sub Get(Key As String) As Object
    Dim rs As ResultSet = sql1.ExecQuery2("SELECT value FROM main WHERE key = ?", Array As String(Key))
    Dim result As Object = Null
    If rs.NextRow Then
        result = ser.ConvertBytesToObject(rs.GetBlob2(0))
    End If
    rs.Close
    Return result
End Sub

ok i found the problem, i have to declare the types in the Main Module and not in another activity (or code module)
