  private static final String TAG = "Chilkat";

  // Called when the activity is first created.

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  Start with an empty MIME object...
    CkMime mime = new CkMime();

    //  Initialize it as multipart/alternative.
    mime.NewMultipartAlternative();

    //  Create a text/plain part.
    CkMime ptMime = new CkMime();
    ptMime.SetBodyFromPlainText("This is the plain text body.");
    Log.i(TAG, ptMime.getMime());
    Log.i(TAG, "****");

    //  The text/plain part looks like this:

    //  	Content-Type: text/plain
    //  	Content-Transfer-Encoding: 7bit
    //  
    //  	This is the plain text body.

    //  Create a text/HTML part.
    CkMime htmlMime = new CkMime();
    htmlMime.SetBodyFromHtml("<html><body><p>This is the <b>HTML body</b></p></body></html>");
    Log.i(TAG, htmlMime.getMime());
    Log.i(TAG, "****");

    //  The text/html part looks like this:

    //  	Content-Type: text/html
    //  	Content-Transfer-Encoding: 7bit
    //  
    //  	<html><body><p>This is the <b>HTML body</b></p></body></html>

    //  Add both parts as children of the multipart/alternative
    mime.AppendPart(ptMime);
    mime.AppendPart(htmlMime);
    Log.i(TAG, mime.getMime());

    //  This the result.  The boundary string was automatically generaetd.
