On Android 11+ you cannot list non-media files, that are not created by the app itself (without using SAF). And even with SAF you cannot list non-media files in the
root dir of the external storage and in the
/Download folder.
So the only way to list all files / duplicates (non-media & media files) is to request and grant MANAGE_EXTERNAL_STORAGE permission.
In this block, i want to take picture with camera and then convert that image to pdf using kio4_pdf after that copy pdf file to /download/gggg.pdf. but there is no pdf file created by kio4_pdf extension. Why that happen?
