title: Uniquely identify Android Wear device
body: <p>What would be the best way to uniquely identify a specific Wear-device? I'd like to store a preference <em>per device</em> on the phone and thus need an identifier that is static. I would expect that the <a href="https://developer.android.com/reference/com/google/android/gms/wearable/Node.html#getId()" rel="nofollow"><code>NodeId</code></a> is assigned dynamically (and changes after each reconnect, or after each reboot, for example).</p>
