title: Android Beacon Library - detect specific UUID only
body: <p>The Android Beacon Library documentation describes using <a href="https://altbeacon.github.io/android-beacon-library/samples.html" rel="nofollow noreferrer">setBeaconLayout</a>
  to match any beacon broadcasting a given BLE pattern of bytes. </p>
  
  <p>This is more flexible than iOS, where we are restricted to finding only beacons for which we pass the specific UUID in advance, However, since this iOS restriction exists, I was wondering if it makes sense to impose the same limitation on ourselves in Android.</p>
  
  <p>Is it possible to pass a specific UUID to setBeaconLayout or some other API so that didEnterRegion, etc. will only be called for a beacon with this specific UUID?</p>
  
  <p>Examples for any protocol (AltBeacon, iBeacon, etc.) would be welcome.</p>
