5A basic sample showing how to add extensions to notifications on wearable using
6[NotificationCompat.WearableExtender][1] API by providing a chat experience.
7
8Introduction
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
14This example also adds the wearable notifications as a voice input by the following code:
15
16```java
17NotificationCompat.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
24Intent intent = new Intent(ACTION_RESPONSE);
25PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,
26        PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
27Notification 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();
36NotificationManagerCompat.from(this).notify(0, notification);
37```
38
39When you issue this notification, users can swipe to the left to see the "Reply" action button.
40
41When you receive the response, you can do it by the following code:
42
43```java
44@Override
45public 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```
