So this is the behavior in preview but testing in thingworx view the popup windows is white and does not display the pdf
So that seem to be some issue ... need further checks...
I asked the development and received the following answer:
I should note that the web view on Android (i.e. Chrome for Android) has no built-in PDF viewing capbility. If you want to view a PDF there you either:
- Use SVG instead (converting as necessary) or
- Allow the PDF to go to an external viewer
Note that there is no guarantee that the device in question will have a PDF viewer, though most do as Google Drive is one such viewer.
I hope is this helpful!
I'm doing that in a different way for experience's performance reasons, you can store your PDF file in Thingworx by deploying an Extension like "File Repository Home Mashup" available in the market place on your Experience Server, once your file uploded you can execute a service to get the PDF file's URL, and use the 2D URL Widget in Studio to give an access to your document.
I hope this can help you.
