Answer 1

The Best way is to use AlarmManager see this link http://www.techrepublic.com/blog/android-app-builder/use-androids-alarmmanager-to-schedule-an-event/

Otherwise you will need to write service to keep track on time.

Good luck

Answer 2

You could use an AlarmManager.

http://developer.android.com/reference/android/app/AlarmManager.html

Set up the alarm to trigger at the time you want to handle your event.

When you complete your event code, set up a new Alarm before you exit.

Note that alarms do not survive a reboot so you would need to set them up again at device boot (if required)
