Monodroid - Multiple Mail Attachment

Question

I'm trying to send a mail along with multiple files attached to it, however I can't get them to be added to the mail. I proceed like this:

private void SendMail (List<Data> ToSend)
    {
        var Attachments = new List<Android.Net.Uri>();
        Intent i = new Intent (Android.Content.Intent.ActionSendMultiple);
        i.SetType ("message/rfc822");
        i.PutExtra (Android.Content.Intent.ExtraEmail, new String[]{"try@mail.com"});
        i.PutExtra (Android.Content.Intent.ExtraSubject, "Test");
        i.PutExtra (Android.Content.Intent.ExtraText, "Test Test...");
        foreach (var content in ToSend) {
            Java.IO.File myFile = new Java.IO.File(content.attachmentloc);
            // attachmentloc is a string containing the absolute path to the file to attach.
            var uri = Android.Net.Uri.FromFile(myFile);
            Attachments.Add (uri);
        }
        i.PutParcelableArrayListExtra(Android.Content.Intent.ExtraStream, Attachments.ToArray());
        StartActivityForResult(Intent.CreateChooser(i, "Send mail..."), 0);
    }

I checked and the path in the string is good.. however the method .Exists (When used on the Java.IO.File in the foreach) returns false. might be the reason why ?

Thanks for the help.

EDIT:

When trying to add a single attachment, it works just fine. However whenever I call a function that imply there will be more than one attachment, it fails.

Aka:

Intent i = new Intent (Android.Content.Intent.ActionSend);
var uri = Android.Net.Uri.Parse (ex._FileLocation);
i.PutExtra(Intent.ExtraStream, uri);

Works just fine however replacing

    Intent i = new Intent (Android.Content.Intent.ActionSend);

By

    Intent i = new Intent (Android.Content.Intent.ActionSendMultiple);

Leads to the same fail and so does replacing:

var uri = Android.Net.Uri.Parse (ex._FileLocation);
i.PutExtra(Intent.ExtraStream, uri);

By

var Attachments = new List<Android.Net.Uri> ();
                foreach (var ex in ToSend) {
                var uri = Android.Net.Uri.Parse (ex._FileLocation);
                Attachments.Add (uri);
                //o
            }
            i.PutParcelableArrayListExtra (Android.Content.Intent.ExtraStream, Attachments.ToArray ());

... I'm using the default mail application (not gmail) I also tried setting the intent type to " * / * " (without spaces) as suggested somewhere else. Also tried AddFlags (ActivityFlags.GrantReadUriPermission);

As it works with a single attachment, I know the URIs are valid for sure...

I'd really need help.

Unless I missed something, my code is most likely the same.. I obviously found that answer before... Yet it wouldn't work for me :/ I probably do something wrong but can't find what. — MagiKruiser, Feb 14 '13 at 11:05

I personally found no valid answer to this problem. Only answer I found is a workaround: compress all the file into a single .zip archive and send that archive as the single attachment.

might be, the mail activity has not enough rights to read your file. Try to add myFile.setReadable(true, false) either when creating file, or here before adding to Attachments array.
