title: Detecting a near by AM/FM Radio
body: <p>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.</p>
  
  <p>Thanks in advance.</p>
