title: Expo get unique device id without ejecting
body: <p><a href="https://github.com/rebeccahughes/react-native-device-info#example" rel="noreferrer">This library</a> allows you to get unique device id / Mac address of Android devices, which doesn't change after reinstallation.</p>
  
  <p><code>Expo.Constants.deviceId</code> changes after every reinstallation (even if the app version number is the same).</p>
  
  <p>Is there a way to get an unique id for Android that doesn't change after reinstallation (at least for if it's the same version), without ejecting?</p>
