I'm trying to create a service that run in background in android.. That service should work only when the device is on sleep (Means that screen is off)..
I think that can be done using a service but I don't know how to detect if the phone is awake or not.. Any Idea ? Thanks..
For screen on-off state, you can try with ACTION_SCREEN_ON and ACTION_SCREEN_OFF intents, as shown in this blog post:

From here : How to detect whether screen is on or off if API level is 4?
