Exception when saving pdf on Android

jvanhu1s · May 31, 2019, 7:38pm

Experiencing an exception when attempting to save a PDF document from Aspose.Words on Android. Looks like Aspose.Resources.TableSubstitutionAndroid.xml is missing for some reason.

Code snippet:

        var doc = new Document();
        string path = Path.Combine(Xamarin.Essentials.FileSystem.AppDataDirectory, "temp_report.pdf"); //Throws Exception
        doc.Save(path, SaveFormat.Pdf);

~ Outer Exception ~

System.TypeInitializationException
Message: The type initializer for ‘Aspose.Words.Fonts.FontSettings’ threw an exception.

@jvanhu1s,

Please check the ‘Xamarin Platform Notes’ and ‘Xamarin.Android Additional Requirements’ sections of the following article:

Xamarin and .NET Standard 2.0 API Differences and Limitations.

Hope, this helps.
