You can use TimerTask Class and Android's Alarm Class. In the TimerTask's Run method keep fetching gps data on particular interval ( suppose on every minute ). And use Alarm Class for closing LocationListener Class & Opening on every hour. This way your application will work very efficiently. I used same for my application. For Auto start on Switch on Mobile, you can use Android Services.

TimerTask's Example is here. AlarmManager's Example is here.

ya , I have developed Location Tracker Application for same purpose, for Auto Start, you can use Android Service. – Lucifer Feb 02 '12 at 06:45
if i use service class is it always run,ie when screen lock,when mobile backlight off? – Mercy Feb 02 '12 at 06:49
am trying the above example but the toast print one time only – Mercy Feb 02 '12 at 08:40
That is because you haven't called it again & again. – Lucifer Feb 02 '12 at 08:42

Usually the device powers down the screen after some time and than also the CPU. If this happens you will not get any more updates from the GPS. To prevent this behavior you need to aquire a WakeLock.

Wakelocks are described here: http://developer.android.com/reference/android/os/PowerManager.html

And here is another article on WakeLocks: How to get an Android WakeLock to work?
