Charts on Android

I cannot open Raster  charts  on qtVlm in my Android devices. I have tried different directories and also the/org/meltemus.qtvlm/files subdirectory but nothing worked, even re-starting the tablet (Galaxy Active3 running Android11) which is my main device.Please look at the image; maybe its because it seems to be impossible to check on the box of the directory adress, as I do in the windows version.
Help?

Hi
Yes the checkboxes should be checked, all is OK here concerning that I can check or uncheck any line. Especially you should be able to check the 2 first ones.
On Android 11 and up files should be stored in /Android/data/org.meltemus.qtvlm/files
you can place rasters for instance into the kaps subfolder and hit the rebuild button
But first thing is to get these lines checked.

Thanks, Philippe! According to yr instructions and after rebooting, it worked.

Now I see it does not switch to the closest scaled chart when I zoom in, maybe I must check some option to do it.
