Android - incremental status bar notification icon

You know what I'm talking about: for example when you get multiple new emails the notification icon in the status bar is augmented with a little red circle that contains number of unread mails. Twitroid has the same icon. Any idea how it's done? I don't think (or so I hope) there are 10000 similar icons. I开发者_开发技巧s this red circle generated and overlaid the notification icon? If so - any code snippets will be much appreciated.

This one is nice and easy, just change Notification.number to whatever number you want to appear on your Notification, e.g.:

Notification notification = new Notification(icon, tickerText, when);
notification.number = 4;

A good example of how to use the notification bar can be found in this tutorial:

Hope it helps, Adrian.
