So the general idea of this is that a group of people will publish PDF documents (Right now they just put them on a shared company network drive). Users on the floor using our Android devices will be able to scan a QR Code at a station which will bring up one of the PDF documents. 

The issues I am running into are:

• Best way to publish these PDF Documents to be accessed by Android Devices
• Best way to Scan and open these PDF documents on the Android Device

I already have this working but I feel like it can work better. Currently users just update PDF documents on their PC's that are stored in a shared network folder. That file server has FTP turned on so then I create a QR Code FTP link (ftp://username:password@server/test.pdf). On the Android device they open Chrome and scan the QR code into the address bar. The PDF downloads and they have to pull down the notification bar to open and view the PDF. 

Using a Windows 10 tablet, I like how I can just use Chrome and scan a link (file://servername/path/tofile/test.pdf) and it will preview the file without downloading it. If someone has done this or knows a way to do this kind of thing on Android I would love to hear how.

Thanks!
