SAF1 - copy db.sqlite to ASD

Install the app, open it, "Access all files" → search "TestToASD" and grant permission.

Connect your device to the computer via USB and you will be able to see it.

So it works with this permission, which is of course a bug with your Samsung device. The ASD no longer requires storage permissions since API 19 (Android 4.4 / KitKat).

Which mistake? As I said...
