[android-developers] Re: Turn Screen Off/on

I need to save energy, i want to make the device sleep during the nigh, without user intervention....

But im having trouble when i try to wake up the device...

I tried something like that:

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

       Calendar calendar = Calendar.getInstance();
       calendar.setTimeInMillis(System.currentTimeMillis());
       calendar.add(Calendar.SECOND, 10);
       //one-shoot:
       //alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
       //repetitive alarm:
       alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 5*1000, pendingIntent);
           
       Toast.makeText(AndroidAlarmService.this, "Start Alarm", Toast.LENGTH_LONG).show();
