How to create a remote control program?

Question

Java

What code in Java can be used to send a signal from the IR port to a TV or something else?

Answer 1

Briefly and to the point, something like this:

ConsumerIrManager mCIR = (ConsumerIrManager) getSystemService(Context.CONSUMER_IR_SERVICE);
mCIR.transmit(carrierFrequency, pattern);

But in general, it will take about fifty more lines of code to properly access the IR sensor, check what it can transmit, smooth out the features of working with it in different versions of Android, and form the necessary values ​​in the variables carrierFrequencyand pattern.
