Type R.drawable.stat_notify_calendar cannot be resolved

I'm trying to make a notification in Android. But i get the error in the title by using:

   Notification notif = new Notification(R.drawable.stat_notify_calendar, tickerText,
           System.currentTimeMillis(开发者_如何转开发));

Do i need to define something before i try to draw it?

For that to work, you need an image in res/drawable/ (or a related resource set) named stat_notify_calendar.* where the * could be png, jpg, etc.
