long when = System.currentTimeMillis();         // notification time
Context context = getApplicationContext();      // application Context
CharSequence contentTitle = "My notification";  // expanded message title
CharSequence contentText = "Hello World!";      // expanded message text

Intent notificationIntent = new Intent(this, MyClass.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

// the next two lines initialize the Notification, using the configurations above
Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
