Open and Show a PDF on Airtap

ctsholo

I have seen in some apps when air tapped a button PDF window opens and user could scroll through it. Something like in this video @1.04 Inspection I tried to implement the same with this code

   var file = await StorageFile.GetFileFromApplicationUriAsync
    (
        new Uri("ms-appx:///3M.pdf")
    );


     Debug.Log("Opening file in path :" + file.Path);

        if (file != null)
        {
            Debug.Log("File found\nLaunching file...");

          //  var options = new Windows.System.LauncherOptions();
         //   options.DisplayApplicationPicker = true;
            // Launch the retrieved file
            var success = await Windows.System.Launcher.LaunchFileAsync(file);

            if (success)
            {
                Debug.Log("File launched successfully");
                // File launched
            }
            else
            {
                Debug.Log("File launch failed");
                // File launch failed
            }
        }
        else
        {
            Debug.Log("Could not find file");
            // Could not find file
        }

But am getting an ArgumentNullException
What do I need to do show a PDF within the app?

I don't believe the Hololens has any native app to open that file type. You might have to create a pdf source file reader / viewer yourself or a find an open source library compiled for UWP that can be integrated. Can you convert your pdf to jpg or png? You can open those as a texture, I don't think the user will know any different that its a pdf.
