Answer 1

I would suggest you to use mu-pdf library.If you want to use MUPDF inside an existing android app project you can follow the guide you find at this link (all credits go to the author, I didn't write this).

Also, as we both (if I understood correctly your needs) need just the PDF rendering features, would be great if someone points out how to (if possible) disable some of the unnecessary features built in the MuPDF library when building it from source (as DjVu support, just as an example).
