Get null when calling getSystemService("CONSUMER_IR_SERVICE")

Question

I'm trying to build a very simple Remote App for my TV. After some research I found the ConsumerIrManagerClass, but when I call this.getSystemService("CONSUMER_IR_SERVICE"); I get null...

The mobile is a Samsung Galaxy S4 so it has an IR Sensor...

Here's the code of my method:

public void btnOnOff_Click(View view) {
 String command = "0000 0073 0000 000c 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0040 0020 0020 0040 0020 0020 0cbf";
 irManager = (ConsumerIrManager) this.getSystemService("CONSUMER_IR_SERVICE");
 irManager.transmit(36000, hexToDec(command));
}

Does anyone know how to solve this?

• Gabe Sechan: Use Context.CONSUMER_IR_SERVICE instead of a hard coded string. You may be using the wrong one.

Answer 1

You should use the Context.CONSUMER_IR_SERVICE constant as parameter.

It's value is "consumer_ir", not "CONSUMER_IR_SERVICE".

Answer 2

Also to be clear: it is an IR emitter, not a sensor. The sensor is on the equipment you are controlling.

Chances are if you are doing: Context.CONSUMER_IR_SERVICE and you get NULL your phone does not support this feature. Try a free IR app in the Play store first to see if that works.
