Show android notification every five minutes

I want to know how to set time for notification. I want to set notification every five minutes, so help me do that.

public class FirstActivity extends Activity
{
    private static final int HELLO_ID = 1;
    //public static final int FLAG_AUTO_CANCEL = 0;`enter code here`
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.firstactivity);

        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.icon;
        CharSequence tickerText = "Hello";
        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);

        RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.statusbarnotification);
        contentView.setImageViewResource(R.id.image, R.drawable.icon);
        contentView.setTextViewText(R.id.text, "Hello, this message is in a custom expanded view");
        notification.contentView = contentView;
        notification.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL;
        Intent notificationIntent = new Intent(getApplicationContext(), SecondActivity.class);
        //PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        notification.contentIntent = contentIntent;
        mNotificationManager.notify(HELLO_ID, notification);
    }

I think that the best way will be to create a service that sets the notification and then activate the service using AlarmManager.
That's the code for the AlarmManager:

private void startAlarm() {
    AlarmManager alarmManager = (AlarmManager) this.getSystemService(this.ALARM_SERVICE);
    long when = System.currentTimeMillis();         // notification time
    Intent intent = new Intent(this, ReminderService.class);
    PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, 0);
    alarmManager.setRepeating(AlarmManager.RTC, when, (AlarmManager.INTERVAL_FIFTEEN_MINUTES / 3), pendingIntent);
}

To control the interval use the constant values or just insert your own value (in milliseconds).

Here is the Service:

public class ReminderService extends IntentService {
    private static final int NOTIF_ID = 1;

    public ReminderService(){
        super("ReminderService");
    }

    @Override
      protected void onHandleIntent(Intent intent) {
        NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        long when = System.currentTimeMillis();         // notification time
        Notification notification = new Notification(R.drawable.icon, "reminder", when);
        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.flags |= notification.FLAG_AUTO_CANCEL;
        Intent notificationIntent = new Intent(this, YourActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent , 0);
        notification.setLatestEventInfo(getApplicationContext(), "It's about time", "You should open the app now", contentIntent);
        nm.notify(NOTIF_ID, notification);
    }
