Android PdfRenderer throws IOException

Question

My application lists PDF files, and when the user selects a PDF, the app opens it. If the user selects a corrupted PDF file, PdfRenderer throws IOException (which is fine, since I catch that exception and inform the user that the file is corrupted).

But the issue is, after this happens, IOException is thrown for all the PDF files the user is trying to open (Even for the non-corrupted ones)

Relevant code

File file = new File(filePath);
mFileDescriptor = ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY);
if (mFileDescriptor != null) {
     mPdfRenderer = new PdfRenderer(mFileDescriptor);
}

Stacktrace

Why is this happening? How can I fix this?

NB : I have already tried copying pdf file to cache directory. It doesn't make a difference.

Same issue in PdfRenderer google sample repo here.

Just commenting that I’m running into the exact same issue. It also appears we’re not the only ones running into this issue. I found this issue (but closed). I may attempt to add my own project and re-file this bug with my own project — codecaffeine, Oct 01 '19 at 15:07
@codecaffeine This [issue](https://issuetracker.google.com/issues/37052344) says it's been fixed in Android P. — Aswin P Ashok, Oct 01 '19 at 15:37
Did you find any solution ? If yes, please share the answer. — K Pradeep Kumar Reddy, Aug 12 '21 at 14:24
@KPradeepKumarReddy Unfortunately, no. The bug is still there. — Aswin P Ashok, Aug 13 '21 at 10:29
