4. Previous Notifications NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_event) .setContentTitle(eventTitle) .setContentText(eventLocation) .addAction(R.drawable.ic_map, getString(R.string.map), mapPendingIntent);; NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this); manager. notificationManager.notify(notificationId, notificationBuilder.build());
5. Wear your Notifications Notification notification = new NotificationCompat.Builder(mContext) .setSmallIcon(R.drawable.ic_message) .setContentTitle(getString(R.string.title)) .setContentText(getString(R.string.content)) .extend(new WearableExtender().addAction(action)) .build();
6. Pages // Create second page notification Notification secondPageNotification = new NotificationCompat.Builder(this) .setStyle(secondPageStyle) .build(); // Extend the notification builder with the second page Notification notification = notificationBuilder .extend(new NotificationCompat.WearableExtender() .addPage(secondPageNotification)) .build();
7. Stack Notification notif2 = new NotificationCompat.Builder(mContext) .setContentTitle("New mail from " + sender2) .setContentText(subject2) .setSmallIcon(R.drawable.new_mail) .setGroup(GROUP_KEY_EMAILS) .build();
8. Stack Notification summaryNotification = new NotificationCompat.Builder(mContext) .setStyle(new NotificationCompat.InboxStyle() .addLine("Alex Faaborg Check this out") .addLine("Jeff Chang Launch Party") .setBigContentTitle("2 new messages") .setSummaryText("johndoe@gmail.com")) .setGroup(GROUP_KEY_EMAILS) .setGroupSummary(true) .build();

13. Let’s Talk
14. Ok Google, K.I.T.T I need you! FAIL!
15. Ok Google, Start K.I.T.T <activity android:name="com.karumi.kittwear.WearMainActivity" android:label="kitt"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name = "android.intent.category.LAUNCHER"/> </intent-filter> </activity> Spanish word for ‘start’ is Iniciar o abrir…
16. Ok Google, Call a car <activity android:name="com.karumi.kittwear.WearMainActivity" android:label="kitt"> <intent-filter> <action android:name = “com.google.android.gms.actions. RESERVE_TAXI_RESERVATION" /> <category android:name = "android.intent.category.DEFAULT" /> </intent-filter> </activity> Spanish word for ‘call a car’ is ???
17. Some voice command are not well documented Preset commands are define on the Android Wear documentation Documentation for spanish command does not exist. Trial and error.
18. Free blah blah blah private void displaySpeechRecognizer() { Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra (RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); startActivityForResult(intent, SPEECH_REQUEST_CODE); }
19. @Override protected void onActivityResult (int requestCode, int resultCode,Intent data) { if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) { List<String> results = data.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS); String spokenText = results.get(0); //TODO Do something with spokenText } super.onActivityResult(requestCode, resultCode, data); }
20. Working with K.I.T.T
21. Only Lolipop you need V4 compat
22. <meta-data android:name="com.google.android.gms.car.application" android:resource="@xml/automotive_app_desc"/> <automotiveApp> <uses name="media" /> <uses name="notification"/> </automotiveApp> automotive_app_desc.xml
23. @Override protected void onActivityResult (int requestCode, int resultCode,Intent data) { if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) { List<String> results = data.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS); String spokenText = results.get(0); //TODO Do something with spokenText } super.onActivityResult(requestCode, resultCode, data); }
24. only two possibilities Audio playback Messaging
25. <application> ... <receiver android:name=".MyMessageReadReceiver"> <intent-filter> <action android:name=“com.myapp.messagingservice. ACTION_MESSAGE_HEARD"/> </intent-filter> </receiver> <receiver android:name=".MyMessageReplyReceiver"> <intent-filter> <action android:name=“com.myapp.messagingservice. ACTION_MESSAGE_REPLY"/> </intent-filter> </receiver> ... </application> Messaging
26. // Build a RemoteInput for receiving voice input in a Car // Notification RemoteInput remoteInput = new RemoteInput.Builder(EXTRA_VOICE_REPLY) .setLabel(getApplicationContext().getString(R.string.not ification_reply)) .build(); // Create an unread conversation object to organize a group of messages from a particular sender. UnreadConversation.Builder unreadConvBuilder = new UnreadConversation.Builder(participantName) .setReadPendingIntent(msgHeardPendingIntent) .setReplyAction(replyPendingIntent, remoteInput);
27. Intent msgHeardIntent = new Intent() .addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES) .setAction(com.myapp.messagingservice.ACTION_MESSAGE_HEARD) .putExtra("conversation_id", conversationId); PendingIntent msgHeardPendingIntent = PendingIntent.getBroadcast(getApplicationContext(), conversationId, msgHeardIntent, PendingIntent.FLAG_UPDATE_CURRENT);
28. NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getApplicationContext()) .setSmallIcon(R.drawable.notification_icon) .setLargeIcon(icon_bitmap) .setContentText(messageString) .setWhen(currentTimestamp) .setContentTitle(participant_name) .setContentIntent(msgHeardPendingIntent); notificationBuilder.extend(new CarExtender() .setUnreadConversation(unreadConvBuilder.build()); NotificationManagerCompat msgNotificationManager = NotificationManagerCompat.from(context); msgNotificationManager.notify(notificationId, notificationBuilder.build());
29. Dark Google Service
