      4 
      5 A basic sample showing how to add extensions to notifications on wearable using
      6 [NotificationCompat.WearableExtender][1] API by providing a chat experience.
      7 
      8 Introduction
      9 ------------
     10 
     11 [NotificationCompat.WearableExtender][1] API offers you a functionality to
     12  add wearable extensions to notifications like [Add the Voice Input as a Notification Action][2].
     13 
     14 This example also adds the wearable notifications as a voice input by the following code:
     15 
     16 ```java
     17 NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
     18         .setContentTitle(getString(R.string.eliza))
     19         .setContentText(mLastResponse)
     20         .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.bg_eliza))
     21         .setSmallIcon(R.drawable.bg_eliza)
     22         .setPriority(NotificationCompat.PRIORITY_MIN);
     23 
     24 Intent intent = new Intent(ACTION_RESPONSE);
     25 PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,
     26         PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
     27 Notification notification = builder
     28         .extend(new NotificationCompat.WearableExtender()
     29                 .addAction(new NotificationCompat.Action.Builder(
     30                         R.drawable.ic_full_reply, getString(R.string.reply), pendingIntent)
     31                         .addRemoteInput(new RemoteInput.Builder(EXTRA_REPLY)
     32                                 .setLabel(getString(R.string.reply))
     33                                 .build())
     34                         .build()))
     35         .build();
     36 NotificationManagerCompat.from(this).notify(0, notification);
     37 ```
     38 
     39 When you issue this notification, users can swipe to the left to see the "Reply" action button.
     40 
     41 When you receive the response, you can do it by the following code:
     42 
     43 ```java
     44 @Override
     45 public int onStartCommand(Intent intent, int flags, int startId) {
     46     if (null == intent || null == intent.getAction()) {
     47         return Service.START_STICKY;
     48     }
     49     String action = intent.getAction();
     50     if (action.equals(ACTION_RESPONSE)) {
     51         Bundle remoteInputResults = RemoteInput.getResultsFromIntent(intent);
     52         CharSequence replyMessage = "";
     53         if (remoteInputResults != null) {
     54             replyMessage = remoteInputResults.getCharSequence(EXTRA_REPLY);
     55         }
     56         processIncoming(replyMessage.toString());
     57     } else if (action.equals(MainActivity.ACTION_GET_CONVERSATION)) {
     58         broadcastMessage(mCompleteConversation.toString());
     59     }
     60     return Service.START_STICKY;
     61 }
     62 ```
