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();
