2. Extend the onCreate method to create this Notifi cation object.
@Override
public void onCreate() {
updateTimer = new Timer(“earthquakeUpdates”);
}
int icon = R.drawable.icon;
String tickerText = “New Earthquake Detected”;
long when = System.currentTimeMillis();
newEarthquakeNotification= new Notification(icon, tickerText, when);
3. Now extend the announceNewQuake method to trigger the Notifi cation after each new earthquake
is added to the Content Provider. Before initiating the Notifi cation, update the extended
details using setLatestEventInfo.
private void announceNewQuake(Quake quake) {
String svcName = Context.NOTIFICATION_SERVICE;
NotificationManager notificationManager;
notificationManager = (NotificationManager)getSystemService(svcName);
}
Context context = getApplicationContext();
String expandedText = quake.getDate().toString();
String expandedTitle = “M:” + quake.getMagnitude() + “ “ +
quake.getDetails();
Intent startActivityIntent = new Intent(this, Earthquake.class);
PendingIntent launchIntent = PendingIntent.getActivity(context,
0,
startActivityIntent,
0);
newEarthquakeNotification.setLatestEventInfo(context,
expandedTitle,
expandedText,
launchIntent);
newEarthquakeNotification.when = java.lang.System.currentTimeMillis();
notificationManager.notify(NOTIFICATION_ID, newEarthquakeNotification);
Intent intent = new Intent(NEW_EARTHQUAKE_FOUND);
intent.putExtra(“date”, quake.getDate().getTime());
intent.putExtra(“details”, quake.getDetails());
intent.putExtra(“longitude”, quake.getLocation().getLongitude());
intent.putExtra(“latitude”, quake.getLocation().getLatitude());
intent.putExtra(“magnitude”, quake.getMagnitude());
sendBroadcast(intent);
4. The fi nal step is to clear and disable Notifi cations within the two Activity classes. This is done to
dismiss the status icon when the application is active.
