title: Android Wear : launching an activty in the handheld on clicking notification action button in wear
body: <p>I want to start an activity in the handheld app and send some data  when the user clicks on notification action button in the wear. I am using below code to build the notification in the wear.</p>
  
  <pre><code>public Notification buildNotification(Context context) {
          PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
                  new Intent(context, MainActivity.class), 0);
  
          return buildBasicNotification(context).extend(new Notification.WearableExtender()
                  .setContentIcon(R.drawable.content_icon_small)
                  .setContentIconGravity(Gravity.START))
                  .addAction(new Notification.Action(R.drawable.ic_launcher,
                          "Action A", pendingIntent))
  
  
                  .build();
      }
  </code></pre>
  
  <p>Is it possible to start the activity in handheld through pending intent only or should we start an service/activity in the wear on clicking action button and from that activity/service send message to the device through message api. Any help would be appreciated!</p>
