I was able to add access to my Dropbox account to Reader on my desktop systems, but don't see a way of doing the same with the Android version. Is there a way of doing this for my tablet?
I am sorry this integration of Acrobat Reader & Dropbox is not available on mobile devices. For mobile device you can download the individual DropBox app.
Dropbox integration is available for Acrobat Reader for iOS (iPad/iPhone) version 15.2 or later.
Stay tuned for Dropbox integration for Acrobat Reader for Android!
