Sending email with downloaded file

[csampaio26]

Steps to reproduce

1. Setting the path for downloaded files

   CrossDownloadManager.Current.PathNameForDownloadedFile = new System.Func<IDownloadFile, string>(file => {
               string fileName = Android.Net.Uri.Parse(file.Url).Path.Split('/').Last();
               return System.IO.Path.Combine(ApplicationContext.GetExternalFilesDir(Environment.DirectoryDownloads).AbsolutePath, fileName);
           });

2. Accessing the file to send it as an attachment

   
   string fileName = Android.Net.Uri.Parse(url).Path.Split('/').Last();

string path = Path.Combine(Android.App.Application.Context.GetExternalFilesDir(Android.OS.Environment.DirectoryDownloads).AbsolutePath, fileName);

            email.PutExtra(Intent.ExtraStream, Android.Net.Uri.FromFile(new Java.IO.File(path)));

            email.SetType("application/pdf");
        }

        Forms.Context.StartActivity(Intent.CreateChooser(email, "Send Email"));

### Expected behavior
It should send the document as an email attachment

### Actual behavior
Instead, it tells that the document has 0 bytes and the receiver doesnt get the document.

Can you share a full example? I e.g. don't know when you're trying to send it via mail.

The best for me would be if you could fork this repo and adjust the sample so you get the behavior you're facing.

I was using the wrong way to download files. I should be doing:

`

                        bool isDownloading = true;
                        CrossDownloadManager.Current.Start(File);

                        File.PropertyChanged += async (sender, e2) =>
                        {
                            if (File.Status == DownloadFileStatus.COMPLETED)
                            {
                                await Task.Delay(100);
                                isDownloading = IsDownloading(File);
                            }
                        };

`

And to attach to the email:

                string fileName = Android.Net.Uri.Parse(url).Path.Split('/').Last();
                string path = Path.Combine(Android.App.Application.Context.GetExternalFilesDir(Android.OS.Environment.DirectoryDownloads).AbsolutePath, fileName);

                var file = new Java.IO.File(path);
                var uri = Android.Net.Uri.FromFile(file);

                email.PutExtra(Intent.ExtraStream, uri);
