If you are asking about scheduling system, a good way is using AlarmManager, which can wake up your activity even if it is not running.

Here is some info: http://developer.android.com/reference/android/app/AlarmManager.html

And here a nice example with Notification: http://android.arnodenhond.com/tutorials/alarm-notification

Register your app with AlarmManager.
