ConsumerIrManager object is null

Question

I defined ConsumerIrManager as following:

ConsumerIrManager irManager = (ConsumerIrManager) getSystemService(CONSUMER_IR_SERVICE);

But for some reason it is null and I can't use functions like .transmit().

Answer 1

You are not guaranteed to get the service. There are multiple cases which can lead to null you are facing, starting from most obvious one, which is lack of hardware support for IR on the device to missing android.permission.TRANSMIT_IR permission declared in your AndroidManifest.xml file. I'd also inspect logcat and look for any related warning or error.
