I am rendering a PDF file with PdfRenderer class. I am using a service to obtain a PDF file, sometimes this returns an invalid or corrupted PDF which is something I am not able to validate until rendering the file.

Once render fails (as expected):
W/System.err: java.io.IOException: file not in PDF format or corrupted
at android.graphics.pdf.PdfRenderer.nativeCreate(Native Method)
at android.graphics.pdf.PdfRenderer.<init>(PdfRenderer.java:166)

When obtaining a new PDF file which is a valid one, PdfRenderer will always fail for any other valid file with similar exception even creating new objects and closing them after first attempt. I saw that nativeCreate is a CPP class but in the PdfRenderer construction, it is out of the try-catch clause but inside the synchronized section so I assume that it could cause a deadlock issue.

I attach PDF examples, ATG KW WPS Report is the corrupted file, the other isn't.

Kind regards,
Alex
