Create an icon for a custom message
You can associate
icons with a custom message. You associate an icon with a custom message's type
and status. For example, you can associate one icon with an unopened message
and a different icon with an opened message. The icon appears on the left side
of a message in the Messages application.

Invoke
EncodedImage.getEncodedImageResource() to create an
icon based on an encoded image. Pass in the file name as an argument.
ApplicationIcon newIcon =
new ApplicationIcon( EncodedImage.getEncodedImageResource( "ml_sample_new.png" ) );
ApplicationIcon openedIcon =
new ApplicationIcon( EncodedImage.getEncodedImageResource( "ml_sample_opened.png" ) );

of the
ApplicationIcon class.
