i installed adobe reader app on my rooted NC. When i open the app i see the message No PDF files available. i have pdfs in the library / my files which i have loaded with Calibre but tapping on any of these just opens them using the built-in pdf reader. I have read several postings stating that Adobe reader and other pdf reader apps work on NC but no one mentions if they had to adjust a setting, load pdfs to a special location or use a file manager app to associate the pdfs with the reader. Can someone tell me what the trick is?
