title: Can an Android device act as an iBeacon?
body: <p>Can an Android device act as an iBeacon and figure out when other Android devices come in its range? Do those other Android devices need to have Bluetooth turned on?</p>
  
  <p>If a customer comes into my shop and he doesn't have my app installed on his device, can iBeacon work, or must he install the app first? There are so many customers are visiting our shop daily, but if they don't have my app installed, does the iBeacon concept work?</p>
