android: notify the user from service

I have to display notification to the user from service always running in background.

I read that we have to use status bar notification to achieve this. But in the status bar icon is very small and user mi开发者_JAVA百科ght miss it. I want to notify user similar to "new call notification" or "new message notification"

Please help me how can I construct such notifications.

Thanks in advance.

'new message notification' uses the same notification api you are talking about it just displays the message in the status bar. A new call is an Activity. You can start an activity from you service like this

startActivity(this, MyActivity.class);

When you create a notification, use

            final Notification notification = new Notification(
                    icon, 
                    "New Message Notification", // <-------
                    System.currentTimeMillis());

Consider using the buzzbox sdk for running background tasks and creating notifications. Have a look at http://hub.buzzbox.com - open source apps are available as examples.
