An on-screen remote must translate button presses into correctly timed infrared commands and handle phones without IR hardware.
THE APPROACH
How it comes together.
A Kotlin activity binds XML remote controls, checks ConsumerIrManager for an emitter, builds Samsung-style pulse timing from command codes, and transmits at 38 kHz.
