// Important: Don't forget to include the call to System.loadLibrary

import android.widget.TextView;

public class SimpleActivity extends Activity {
// Called when the activity is first created.

boolean success;
// An MDN can be used to notify the
// sender of a message of any of several conditions that may occur after
// successful delivery, such as display of the message contents,
// printing of the message, deletion (without display) of the message,
// or the recipient's refusal to provide MDNs.
// (for more information, see RFC 3798)
// IMPORTANT:
// Note: Please be careful in sending automated MDN's.
// It is important to be aware of an issue called "backscatter".
// See the Wikipedia article here: http://en.wikipedia.org/wiki/Backscatter_%28e-mail%29
// The CreateMdn method is called to create a new
// MDN email based upon the email object calling CreateMdn.
// The email object instance used to call CreateMdn would
// typically be an email received from a POP3 or IMAP server.
// In this case, to simplify the example, we'll load the email
// from a .eml file.
// This example will be creating a MDN for "someEmail.eml"
success = email.LoadEml("someEmail.eml");
if (success != true) {
outStr += email.lastErrorText() + "\n";
tv.setText(outStr);
setContentView(tv);
return;
}
// The MDN created by CreateMdn will contain a
// "message/disposition-notification" MIME sub-part that will
// be composed of a number of name-value pairs.
// See RFC 3798 ( http://tools.ietf.org/html/rfc3798 )
// The name-value content for this part is passed
// as XML to CreateMdn. This part of the example
// prepares the XML:
CkXml xml = new CkXml();
// For this example, we're just adding a few name-value pairs.
// These should not be considered to be correct, required or
// even sensible -- they are simply for the example.
xml.put_Tag("DispositionFields");
xml.NewChild2("Disposition","manual-action/MDN-sent-manually; displayed");
xml.NewChild2("Original-Message-ID",email.getHeaderField("Message-ID"));
xml.NewChild2("Final-Recipient",email.getToAddr(0));
String xmlStr;
xmlStr = xml.getXml();
// The last argument to be passed to CreateMdn will be a boolean
// indicating whether to include the entire MIME of the calling
// email object in the MDN, or only the header.
// It may make sense to include the entire email for small emails,
// but for large emails (with large attachments) it's probably
// best to make the MDN header-only.
boolean bHeaderOnly;
bHeaderOnly = true;
// The first argument to be passed to CreateMdn will
// be a human-readable explanation that will be placed
// into the 1st MIME part of the MDN (see RFC 3798).
String humanReadableExplanation;
humanReadableExplanation = "Blah blah blah. Your message has been received and displayed. Blah blah blah";
// OK, we're ready to create MDN...
CkEmail mdnEmail;
mdnEmail = email.CreateMdn(humanReadableExplanation,xmlStr,bHeaderOnly);
if (!(mdnEmail == null )) {
// Show the MIME of the source (original) email:
outStr += email.getMime() + "\n";
outStr += "**************************************" + "\n";
// Show the MIME of the MDN email:
outStr += mdnEmail.getMime() + "\n";
}
else {
outStr += email.lastErrorText() + "\n";
}
// Sample output showing the MIME of the original email,
// and the MDN email created based upon it:
