title: Android wifi sniffer: find nearby devices
body: <p>There are a lot of public places where your mobile phone is used for tracking. Your mobile device is used as identifier, for example: <a href="http://www.bbc.co.uk/news/technology-23665490" rel="noreferrer">http://www.bbc.co.uk/news/technology-23665490</a></p>
  
  <p>Is it possible to use an Android device as scanner to find the MAC addresses of nearby mobile devices? </p>
  
  <p>I've found examples to scan Access points on an Android device but was not able to find more information about scanning for other devices.</p>
