I am a newbie android developer, so pardon me if this question seems too obvious. I want to create an app that would detect any nearby radios (by nearby I mean 15-20 feet, not far), say a radio in the living room, or detecting the radio in my car from the garage etc. I wanted to know if this is possible at all, if so is there any inbuilt android function that I should learn about or is there any API available. I have come across RIL (Radio Interface Layer) but that doesn't seem to solve the prob. Suggestions appreciated.

Thanks in advance.

No, since "an AM/FM radio" does not transmit any signals, let alone any that an Android device could detect.

  • Amend to "AM/FM radio receiver" and it becomes unambiguous. – Howard Jun 03 '13 at 14:21
  • Thank you for the answer. But, as we know that a radio transmits and receives radio waves/signals, can't we detect the instrument by detecting the radio waves/signals around us? Just a thought. – user1652925 Jun 03 '13 at 14:25

    @user1652925: "But, as we know that a radio transmits" -- 99.99% of "AM/FM radio" devices do not transmit. – CommonsWare Jun 03 '13 at 14:47

    @user1652925 Every radio I've ever seen only receives signals, not transmits them. There are some android devices that that can receive AM/FM signals so you can listen to radio stations through your device, but these are the signals coming from the radio station towers, not a radio, so that doesn't seem to be what you are interested in. – FoamyGuy Jun 03 '13 at 14:59
