Press the Send Email button to email an attached image.png file. At start of app, a directory is created on the sdcard at /mnt/sdcard/EmailAttachmentSend. The image.png file is copied from the app's resources drawable to the created directory. Upon send of the email, the To, CC, subject, message, and attached files are setup. Any number of To, CC emails can be applied as well as any number of attached files although only one file is attached. Android Intent ACTION_SEND_MULTIPLE is used to send the email. The intent pops-up a ContextMenu with options for GMail and SMS.
