Check if notification LED exists on device and which colors are available

Question

I've implemented red LED light for my notifications for test purposes, but...

Do I have to check if the device has LED (in case that device doesn't have this feature) and if so how to do it? Also, are LED colors predetermined?

I tried to find some docs or thread that would give me an answer for these questions but had no luck...

Answer 1

There is no way of doing this.

According to Can I detect the presence/absence of 'LED notification' on an Android device?

Most hardware features are exposed via the package manager:

PackageManager pm = getActivity ().getPackageManager ();
boolean hasBluetooth =  pm.hasSystemFeature(PackageManager.FEATURE_BLUETOOTH);

But not this one.

There is a feature request on record as well: https://code.google.com/p/android/issues/detail?id=38481
