Have a look at the following classes:
ApplicationMessageFolder
ApplicationMessageFolderRegistry
And the following interfaces:
ApplicationMessage
ApplicationMessageFolderListener
Register a folder for your app, add a listener to the folder, and use the AppicationMessageFolder.fireElementAdded() method to add status messages to the folder. When the user clicks on the notification bar, the Messages app displays the available folders and their contents. When the user clicks on one of your status messages, the folder's listener will notify your app so it can react accordingly.
