问题
I have been looking for the ability to disable and enable the LED notification light through code. I saw this thread Disable/enable notification led, but it is quite old and I was wondering if the new API versions has some support for turning it off completely.

You cannot enable or disable the LED behavior through the Android SDK, except within your own app, where you control what any Notification does that you raise.
回答2:
You can only control the led if your app raies a notification when no other apps have raised a notifiction.
It is possible on some devices to bypass android and control it directly in unix shell, but this is obviously not recommended.
