Load PDF from API in Xamarin.Android not working.

[Antonio Raynor]

Hi,

 I have successfully loaded PDFs from Assets in my Xamarin.Android project,  but I want to also load PDFs from an API source.

(To test the pdfViewer, I have built a working demo with Xamarin.Forms which loads my document from my API so I am satisfied that it will work.)

Below is a snippet of my Xamarin.Android code that currently does not show my PDF.

                    Stream pdfStream = _apiHelper.DownloadPdfStream(pdfHandbook);

                   

                    _pdfViewer.LoadDocument(pdfStream);

                   

                    _pdfViewer.Toolbar.Enabled = false;

                   

                    _pdfViewer.AnnotationSettings.HandwrittenSignature.Color = Android.Graphics.Color.Blue;

                    _pdfViewer.AnnotationSettings.HandwrittenSignature.Thickness = 2;

...

        

               public Stream DownloadPdfStream(string source)

              {          

                    var endpoint = $"https://documents.azure.net/{source}";

           

                    var uri = new Uri(endpoint);

                   return m_webClient.OpenRead(uri);

               }
