I do this:

SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
boolean used = sp.getBoolean("notif_used", false);

if ( used )
 return;
else {
 /* show the notification */
 Editor editor = getSharedPreferences().edit();
 editor.putBoolean("notif_used", true);
 editor.commit();
}

If your question is about preventing the display of notifications once the user clears one of your previous notifications, you'll probably need to maintain your own data structure to monitor this.

The idea is:

  • Store a hashtable/hashset/other data structure indicating which notifications the user has already seen.
  • Before showing a notification, check the hashtable – if the notification is in there, don't show it. Otherwise, show it.
  • When showing a notification, add it to the hashtable.
  • Flush the hashtable every so often.

You might also want to look into Notification.deleteIntent.

Caution: Before doing this, consider if this is really necessary. It might be sufficient to simply collapse visible notifications by reusing notification IDs.
