Re: [android-developers] Handler.postDelayed not working when screen goes off
I started by using timer() but that done the same thing, basically when the times up it makes a noise then starts the next timer in a que (Intervals), but I would like this to happen when the screen goes blank.

Your problem is that the CPU is stopping as part of sleep mode. This is generally A Really Good Thing from a power management standpoint. What are you trying to accomplish via postDelayed() that is supposed to keep going after the device falls asleep? -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.2 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Handler.postDelayed not working when screen goes off
Either acquire a wake lock, or use alarm manager with a pending intent and a broadcast receiver. You might still need a wake lock in the second case so that the phone doesn't sleep immediately after the alarm is processed by your receiver. -- Kostya Vasilyev -- http://kmansoft.wordpress.com 20.11.2010 23:58 пользователь "Paul Townsend" написал: I made a simple countdown timer and it works as expected when plugged in via usb for debugging but when I take it off debugging and the screen goes off either time out or power button the handler fails to fire at the end time.
