I tried getting the light to flash on 3 different platforms with Android 4.4, 6.0.1 and 4.2.2. It didn't work on any of them. The other notify methods like AutoCancel, sound and vibrate all worked well.
I followed your link to the Notification Builder Library but was not able to install it. It uses the android-support-v4.jar file which is no longer available in the current version of the Android SDK. I was not able to locate the file elsewhere. I posted a reply to the author.
I already tried this as per the library installation instructions. I still get the error "Cannot find: C:\Program Files (x86)\Anywhere Software\Basic4android\libraries\android-support-v4.jar"
I found that this line needs to be added to the attributes section of the app and NOT to the manifest editor as per the installation instructions. But unfortunately this also does not turn on a light on any of the 3 phones I tested. I tried both DefaultLight and setCustomLight. Neither worked.
Yes I see/hear/feel the notifications when the screen is off and surprisingly the light also flashes. It's only when the screen is on that the light doesn't flash.

I guess I never thought about this but yes, it looks like the light flashes only when the screen is off. I assumed that it was something that could be controlled by the app. Thanks.
