PDFView shows garbage or blank screen

I am creating a file object and pass it to PDFView using the following code:

 try {
                URL url = new URL(urls[0]);
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.connect();

                if(conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
                    return "Server returned HTTP " + conn.getResponseCode() + " "
                            + conn.getResponseMessage();
                }

                //Useful to display progress
                int fileLength = conn.getContentLength();


                //Download the file
                InputStream input = new BufferedInputStream(conn.getInputStream());
                File dir = new File(getFilesDir(), "/temp");
                dir.mkdir();
                file = new File(dir, "temp.pdf");
                OutputStream output = new FileOutputStream(file);

                byte[] data = new byte[1024];
                long total = 0;
                int count;
                while ((count = input.read(data)) != -1) {
                    if(isCancelled()) {
                        input.close();
                        return null;
                    }
                    total += count;

                  
                    output.write(data);

                }


                output.flush();
                output.close();
                input.close();
            } catch (IOException e) {
                Log.e(LOG_TAG, "IOException: " + e.getMessage());
            }
PDFView pdfView = findViewById(R.id.pdfView);
            pdfView.fromFile(file).load();

The resulting pdf view is blank or shows garbage characters for most pages (I am going to load mostly PDF files containing Persian and Arabic script). How can this be solved?

maybe,you didn’t put PDFView in a RelativeLayout

@djnotes I tried writing fos.write(buffer, 0, count); but still, it was showing invalid characters like İ, ş. Does anyone knows how to fix this issue?
