2===================================
3
4A basic sample showing how to add extensions to notifications on wearable using
5[NotificationCompat.WearableExtender][1] API by providing a chat experience.
6
7Introduction
8------------
9
10[NotificationCompat.WearableExtender][1] API offers you a functionality to
11 add wearable extensions to notifications like [Add the Voice Input as a Notification Action][2].
12
13This example also adds the wearable notifications as a voice input by the following code:
14
15```java
16NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
17 .setContentTitle(getString(R.string.eliza))
18 .setContentText(mLastResponse)
19 .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.bg_eliza))
20 .setSmallIcon(R.drawable.bg_eliza)
21 .setPriority(NotificationCompat.PRIORITY_MIN);
22
23Intent intent = new Intent(ACTION_RESPONSE);
24PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,
25 PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
26Notification notification = builder
27 .extend(new NotificationCompat.WearableExtender()
28 .addAction(new NotificationCompat.Action.Builder(
29 R.drawable.ic_full_reply, getString(R.string.reply), pendingIntent)
30 .addRemoteInput(new RemoteInput.Builder(EXTRA_REPLY)
31 .setLabel(getString(R.string.reply))
32 .build())
33 .build()))
34 .build();
35NotificationManagerCompat.from(this).notify(0, notification);
36```
37
38When you issue this notification, users can swipe to the left to see the "Reply" action button.
39
40When you receive the response, you can do it by the following code:
41
42```java
43@Override
44public int onStartCommand(Intent intent, int flags, int startId) {
45 if (null == intent || null == intent.getAction()) {
46 return Service.START_STICKY;
47 }
48 String action = intent.getAction();
49 if (action.equals(ACTION_RESPONSE)) {
50 Bundle remoteInputResults = RemoteInput.getResultsFromIntent(intent);
51 CharSequence replyMessage = "";
52 if (remoteInputResults != null) {
53 replyMessage = remoteInputResults.getCharSequence(EXTRA_REPLY);
54 }
55 processIncoming(replyMessage.toString());
56 } else if (action.equals(MainActivity.ACTION_GET_CONVERSATION)) {
57 broadcastMessage(mCompleteConversation.toString());
58 }
59 return Service.START_STICKY;
60}
61```
