If you are using Android 6 or higher, you need to get permission to
access the file system. Take a look at the "AppOpenFileDialogDemo1"
example. Include in your program the procedures "procedure
TAndroidModule1.AndroidModule1JNIPrompt (Sender: TObject); procedure
TAndroidModule1.AndroidModule1RequestPermissionResult (...".

maybe you can try like this:

permission granted
copy your db.

1. make sure permission is granted (to make sure just read apps info,
does it granted or not)
2. re check your db file
3. copy your db on dextination folder

I have experience that jtextfilemanager can copy DBF files  to SD .
So you can try it.

Google not talking a lot about LAMW, samples provided are the best
friend.

For examples LAZARUS-LAMW>menu>tools>example project is best.
For easy to understand Laz4andoid 2.0.0 is better than advance
