I have PDFs with hyperlinks (linking to other pages in the document as well as external websites) and would like to be able to use the links provided. The Adobe Reader app and other apps I've tried (VuDroid, droidreader, android PDF reader) don't have this functionality. I did find ezPDF which should work, but it is not free (only 99 cents). I am looking for a way to do this for free because this is for an app I am writing that will need to display a PDF. It will be much more appealing to the client - though still not perfect - if their users only have to download a free PDF reader, for example, to use with my app rather than requiring them to purchase a PDF reading app (even if it is only 99 cents).
Adobe Reader can follow hyperlinks in PDF documents.
The problem (currently, 2014-09-17) is that the default application associated with PDF documents is Quickoffice, and Quickoffice doesn't have this implemented. Installing Adobe Reader allows you to choose (and optionally remember your choice) what app to use.
