I would love to have help on this as well. I store all of my medical journal articles in evernote as pdfs and am constantly opening these up on the Adroid platform. I would love to be able to highlight and then save directly back into evernote. I have tried a number of pdf readers and have not found one that offers this functionality. It works great on my desktop. I open a pdf in Adobe pro, make my highlights, save the file and the highlights are available in that note. Bring this to android, please!
