Can't open PDF in PDF viewer apps

Question

I've got a class to open a blank character sheet (for a LARP) stored in my raw resources and then add some values to the empty fields using iText. The PDF is getting stored in /data/data/package/files just fine, but when I try to use the OpenPDF method, I get an EACCES (permission denied) error. If I try to use adb to export it to my computer, I can open it in PDF viewers/editors with no problems.

Still fairly new to android development, so I have no idea why I'm getting Permission Denied.

Found my own solution. Changes marked with comments below. Correct me if I'm doing something I shouldn't. Discovered "External vs Internal" file storing was my issue.
