Use AlarmManager refer this and tutorial with PendingIntent

Answer 2

I suggest the code will be like this.

// the scheduler
protected FunctionEveryHour scheduler;


// method to schedule your actions
private void scheduleEveryOneHour(){

        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, 
                                                                 new Intent(WAKE_UP_AFTER_ONE_HOUR), 
                                                                 PendingIntent.FLAG_UPDATE_CURRENT);

        // wake up time every 1 hour
        Calendar wakeUpTime = Calendar.getInstance();
        wakeUpTime.add(Calendar.SECOND, 60 * 60);

        AlarmManager aMgr = (AlarmManager) getSystemService(ALARM_SERVICE);        
        aMgr.set(AlarmManager.RTC_WAKEUP,  
                 wakeUpTime.getTimeInMillis(),                 
                 pendingIntent);
}

//put this in the creation of service or if service is running long operations put this in onStartCommand

scheduler = new FunctionEveryHour();
registerReceiver(scheduler , new IntentFilter(WAKE_UP_AFTER_ONE_HOUR));

// broadcastreceiver to handle your work
class FunctionEveryHour extends BroadcastReceiver{
        @Override
        public void onReceive(Context context, Intent intent) {
                // if phone is lock use PowerManager to acquire lock

                // your code to handle operations every one hour...

                // after that call again your method to schedule again
                // if you have boolean if the user doesnt want to continue
                // create a Preference or store it and retrieve it here like
                boolean mContinue = getUserPreference(USER_CONTINUE_OR_NOT);//

                if(mContinue){
                        scheduleEveryOneHour();
                } 
        }
}

hope that helps :)
