Is it possible to capture/receive IR signals in an Android application?

Question

Is there any ways to receive IR signals in android?

While searching, I found ways to transmit data from Android devices.

Found this one very useful: https://github.com/rngtng/IrDude

So, is it also possible to receive IR signals generated by other IR transmitting devices like Remotes? If yes, i want to print those signals (hex values) in my app UI. Can anybody give some light on the issue, please... :)

I'm using Galaxy S4 for development.

Few Android devices have any IR support, let alone some sort of IR receiver. If you build your own device, you are welcome to do what you want.

Answer 2

My idea is>> Cameras detect IR LED flashing. Capture the the signal through android camera. if you know the encoding signal of IR transmitter you can decode it. its very interesting question you raised. I wish to work on it if i got time.:)

Answer 3

EVERY smartphone has an IR transmitter AND and IR receiver.

It is used to detect when your phone is on your ear to disable the touch-screen, so your ear doesn't tap "back" while you are talking.

This IR element is programmable. The IpBike guy uses this in his app; see here: http://www.iforpowell.com/cms/index.php?page=run-time

Some devices (eg: Samsung S6 Edge) have a second IR element as well, pointing a different way, specifically for controlling TVs etc.
