Hi,

I have developed an Xamarin application that in Modal show a pdf in a PdfViewer.

PdfViewerPage pdfViewer = new PdfViewerPage(item.IdAllegato, item.Path, item.FlagScaricabile);
Navigation.PushModalAsync(pdfViewer);

 

When the Modal is open, I assign a url to the PdfViewer source.

pdfViewer.Source = new Uri(uri);

 

Everything is fine when I run the android app on debug mode, but when I run in release mode the PdfViewer show this message: "an error occurred while loading the document"

Hello Giuseppe, 

I am not sure what could be the issue as in debug mode the pdf is displayed in the viewer.

As you are getting an error -> In order to get the exception message you can use the SourceException event. For more details please check the PdfViewer Source Exception Handling topic -> https://docs.telerik.com/devtools/xamarin/controls/pdfviewer/pdfviewer-sourceexception 

private void PdfViewerSourceException(object sender, SourceExceptionEventArgs e)
{
    var error = e.Exception.Message;
}

Then based on the exception we can continue investigating the case. In addition, you can send us the pdf document. Open a support ticket and attach the document to it, because in the forum only image attachments are allowed. 

Regards,
Didi

Hi,

thank you for the support. I have used the SourceException event and I solved the problem. The pdf url had http instead of https.

Best regards,

Davide
