 * notifications on the handset and the watch:
 * <ul>
 * <li>The first button builds a simple local-only notification on the handset.</li>
 * <li>The second one creates a wearable-only notification by putting a data item in the shared data
 * store and having a {@link com.google.android.gms.wearable.WearableListenerService} listen for
 * that on the wearable</li>
 * <li>The third one creates a local notification and a wearable notification by combining the above
 * two. It, however, demonstrates how one can set things up so that the dismissal of one
 * notification results in the dismissal of the other one.</li>
