     31             This sample is a phone application that provides a chat experience in which users can respond to
     32             messages with a quick voice response. New messages create a notification with a "Reply" action.
     33             The notification is bridged from phone to wearable, and selecting the "Reply" action on the
     34             wearable opens the voice transcription UI allowing the user to speak a response.

     68 [NotificationCompat.WearableExtender][1] API offers you a functionality to
     69  add wearable extensions to notifications like [Add the Voice Input as a Notification Action][2].
     70 
     71 This example also adds the wearable notifications as a voice input by the following code:
     72 
     73 ```java
     74 NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
     75         .setContentTitle(getString(R.string.eliza))
     76         .setContentText(mLastResponse)
     77         .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.bg_eliza))
     78         .setSmallIcon(R.drawable.bg_eliza)
     79         .setPriority(NotificationCompat.PRIORITY_MIN);
     80 
     81 Intent intent = new Intent(ACTION_RESPONSE);
     82 PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,
     83         PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
     84 Notification notification = builder
     85         .extend(new NotificationCompat.WearableExtender()
     86                 .addAction(new NotificationCompat.Action.Builder(
     87                         R.drawable.ic_full_reply, getString(R.string.reply), pendingIntent)
     88                         .addRemoteInput(new RemoteInput.Builder(EXTRA_REPLY)
     89                                 .setLabel(getString(R.string.reply))
     90                                 .build())
     91                         .build()))
     92         .build();
     93 NotificationManagerCompat.from(this).notify(0, notification);
     94 ```
     95 
     96 When you issue this notification, users can swipe to the left to see the "Reply" action button.
     97 
     98 When you receive the response, you can do it by the following code:
     99 
    100 ```java
    101 @Override
    102 public int onStartCommand(Intent intent, int flags, int startId) {
    103     if (null == intent || null == intent.getAction()) {
    104         return Service.START_STICKY;
    105     }
    106     String action = intent.getAction();
    107     if (action.equals(ACTION_RESPONSE)) {
    108         Bundle remoteInputResults = RemoteInput.getResultsFromIntent(intent);
    109         CharSequence replyMessage = "";
    110         if (remoteInputResults != null) {
    111             replyMessage = remoteInputResults.getCharSequence(EXTRA_REPLY);
    112         }
    113         processIncoming(replyMessage.toString());
    114     } else if (action.equals(MainActivity.ACTION_GET_CONVERSATION)) {
    115         broadcastMessage(mCompleteConversation.toString());
    116     }
    117     return Service.START_STICKY;
    118 }
    119 ```
