How are you intending to view the pdf ?
The issue you have is that you have stripped the file path from the files to make your listview.
You will need to get the selection index of your selected file, and correspond that with the original list returned by TaifunFile (fileList), then use this to display your pdf.
My extension ViewPDF, seems to work with most file locations (testing on Android 10, companion), but not sure about external sd cards...)
