Download problem on Blackberry and Android Browser

Nov 21, 2012 11:28 AM|LINK

Hi All,

I've trouble with my web apps, im using MVC3, here is my scratch code :

public FileResult ViewPRAttachAjax(Int64 Id)
        {
            //String StrCode = Request["q"].ToString();
            //Int64 Id = Int64.Parse(StrCode);
            //nulis ke file
            RequsitionAttachmentRepository reqAttach = new RequsitionAttachmentRepository();

            RequsitionAttachmentViewModel att = reqAttach.GetAttachment(Id).SingleOrDefault();
            var physicalPath = Path.Combine(Server.MapPath("~/Content/Files/"), att.FileName);
            byte[] MyData = new byte[att.AttachReq.Length];
            using (FileStream fs = new FileStream(physicalPath, FileMode.Create, FileAccess.Write))
            {
                MyData = att.AttachReq;
                fs.Write(MyData, 0, System.Convert.ToInt32(att.AttachReq.Length));
                fs.Close();
                fs.Dispose();
            }
            return File(physicalPath, "application/octet-stream", att.FileName);
         }

The method works fine on IPhone (safari), Android (Opera and Dolphin) and Windows Mobile (IE)...

However user encounter problem when accessing from Blackberry (default browser) and Andoid (default browser). They always cannot download the file requested. Somehow it always failed, or download unsuccessfull.

I've tried many ways, also i change the code

return File(physicalPath, "application/octet-stream", att.FileName);

into

return File(physicalPath, "application/pdf", att.FileName);
return File(MyData, "application/octet-stream", att.FileName);
return File(MyData, "application/pdf", att.FileName);

Is there anybody has suggestion how can i solve my problem ??
