Android Question Update Android Studio app

from AS App you need to copy the db to a place where App B can read it.
App B can not access the path from App A and vice versa.

Thanks DonManfred
the two applications have the same path, it only varies in the folder "db" for AndroidStudio and "F" for b4A

the packagenames, yes. Like it wrote; you can not access the path from another app.
Copy the file to a place where both app can access them. Or share the file with FileProvider (the Tutorial is about B4A but it also work in Android Studio) with the other App.
