Question

I have a Nexus-S which has no external notification LEDs to show a missed call, text message or email. What are some ways to implement a notifcation application? Write a service? write screen blanking application and draw on the app screen when blanked (what about locking?). I thought I would try turning on the hardware key back-lights as a notification but that proves to need root access so that’s out. Please don’t link to an app on the market unless it’s Open Source. Thanks

What are some ways to implement a notifcation application?

I do not know what a “notification application” is. To notify users (e.g., flash LED where available), use a Notification, with whatever mix of options you want on it (e.g., play a ringtone).

Write a service?

A service can raise a Notification.

write screen blanking application and draw on the app screen when blanked (what about locking?)

Users do not necessarily appreciate activities appearing out of nowhere. If you go this route, give them the option of a classic Notification or your activity.
