That is impossible. You cannot embed other applications' UIs into your app.

Put that information into the PDF file itself.

As far as I know, I don't think it's possible. You can however fire intents which can be captured by an appropriate application on the phone. This is handled by the OS. I don't know if there is any intent for opening PDFs. Here is a useful library for intents though: http://www.openintents.org/en/intentstable. See if you can find something there.
