For starters, PDF files are binary, not text. That means you can't use Readers to work with them, you need to use Streams.

So the actual problem is how to get an InputStream from a file on the SD card? The Android Dev Guide has a page called "Data Storage" that talks about using SD cards.

Not just FileReader - all Readers and Writers. It's crucial that you understand the difference between text files and binary files.

I have no idea whether PDFBox works on Android, but I pointed you to a resource that explains how to get an InputStream from a file on an SD card, and it seems that PDDocument.load can use an InputStream as well as a Reader. What else are you looking for?
