• can you post your code?

  I believe you are trying to do a mime attachment. I haven't seen an example of that yet.

  var emailDialog = Titanium.UI.createEmailDialog();
  emailDialog.subject = "Hello from Titanium"; 
  emailDialog.toRecipients = ['nowhere@nowhere.com']; 
  emailDialog.messageBody = '<b>Appcelerator Titanium Rocks!</b>'; 
  var f = Ti.Filesystem.getFile('cricket.wav');         emailDialog.addAttachment(f); 
  emailDialog.open();
