So I have a program that mails invoices via text. eg Click here to see your invoice: http://asdasdf.net/invoice?id=3
The link is a pdf file. On Iphone this works great...a user clicks this and it opens the pdf in a viewer so they see it. But on Android, they are prompted to just save/download it which to me is a far inferior user experience.
How can I be sure that a user will see (not just download) the pdf they click on?
