Will the CountDownTimer work when the phone gone to sleep mode? If it doesn't, is there a broadcast receiver which I can detect whether the phone gone to sleep and awake again?

From everything I read, by default, a Service should stop running after the phone is in sleep mode. This is what I want, but for some reason, the Service is continuing to run when the phone is sleeping. I am starting it with the startService in my app's only activity. How can I make my service stop when my phone is sleeping and then start back up when the phone is turned back on?
I m new to android world n m trying to make an app that wakes up my device from standy mode at a particular time.
I tried a few places where they mentioned about wakelock but this thing just prevents the device from going into standy mode.
I basically want my device to wake up from standby mode.
Like take the example of alarm clock... once set i can leave it and at that time from standby mode I get to see that the phone is active.
I even tried developer site for android... but it wasn't much helpful!
Any help would be highly appreciated!
You have to use Alarm Manager to schedule a repeated alarm (use RTC_WAKEUP for type parameter).
Then your code will execute even if the device is sleep. but notice that the registered alarm will removed once the device is restarted so you have a re-schedule the alarm again (by listening to boot broadcast)
I am making an interval timer for a stopwatch APP, and I'm using chronometer to display notifications (Run, walk, stop) and play sound. But when the phone is in sleepmode it doesn't do anything.
Is there a way to wake up the phone, to show these notifications (and play the sound), or must I use AlarmManager?
I know how to make the phone stay awake with wakelock and FLAG_KEEP_SCREEN_ON, but I don't know how to awake it from sleep.
Use AlarmManager. There is nothing else timer-based that will wake up the device out of sleep mode.
I want a alarm System in my application, I want to open a dialog activity when alarm is fired,
it's working fine when phone is active, but the broadcast receiver is not working when phone is sleep or standby mode.
I also use wacklock logic in broadcast receiver but it can't work well.
you need to write service for that keep working in when phone is sleep or standby mode here is the link
Is there a way to detect when the android system has resumed from sleep mode, but has not turned on the screen? My service does not need to acquire any wake locks, but does need to know when the device has been woken up by another process.
