Android Question Can we use Mobile's camera as IR decoder ( receiver )

Do you mean proximity sensor?

Dear all

Greetings,
There is any way to make IR receiver using built-in camera of mobile instead of using external HW (IR receiver + AVR say)
I hope that app built with B4A + built-in camera
Thanks on advance.
Best regards

In xiomi mobiles, there is option to transmit IR but not receive IR .In many phones, the 'Volume up' button can be used to capture image. So if you can transmit volume up code to the mobile, you can take picture. However if you mean detect IR using camera, the easiest way is to check for red pixels in camera view finder - when ever any button on IR remote is pressed, a red glow appears which cannot be seen by naked eyes but can be seen by camera.
