Additionally, you can set notification information through public

member variable assignment, like this:

notify.icon = R.drawable.android_32;
notify.tickerText = "Hello!";
notify.when = System.currentTimeMillis();

You need to set a couple more pieces of information before the call

to the notify() method takes place. First,we need to make a call to

the setLastEventInfo() method, which configures a View that

displays in the expanded status bar. Here is an example:

Intent toLaunch = new Intent
(SimpleNotificationsActivity.this,
SimpleNotificationsActivity.class);
PendingIntent intentBack = PendingIntent.getActivity
(SimpleNotificationsActivity.this, 0, toLaunch, 0);
notify.setLatestEventInfo(SimpleNotificationsActivity.this,
"Hi there!", "This is even more text.", intentBack);

Next, use the notify() method to supply the notification’s title and

body text as well as the Intent triggered when the user clicks on

the notification. In this case, we’re using our own Activity so that

when the user clicks on the notification, our Activity launches

again.

Working with the Notification Queue

Now the application is ready to actually notify the user of the

event. All that is needed is a call to the notify() method of the

NotificationManager with an identifier and the Notification we

configured. This is demonstrated with the following code:

private static final int NOTIFY_1 = 0x1001;
// ...
notifier.notify(NOTIFY_1, notify);
